The Cartier Santos is the watch that started it all. Designed in 1904 for Brazilian aviator Alberto Santos-Dumont, it was one of the first wristwatches ever made and is arguably the most influential. The modern Santos family now spans two distinct collections (the sport-leaning Santos de Cartier and the dressier Santos-Dumont) across roughly twelve active references from $7,750 in steel up to €49,000 in platinum.
This guide covers every modern Santos worth knowing, including the major 2026 W&W releases, what the secondary market actually charges, and which configuration suits which buyer.

The Short Answer
If you want one Santos and need the decision framework fast:
- For first-time Cartier ownership in steel: The Santos de Cartier Large WSSA0018 at $8,650 retail / ~$6,867 pre-owned. The volume reference, 39.8mm by 47.5mm, SmartLink bracelet, calibre 1847 MC.
- For a slightly smaller proportion: The Santos de Cartier Medium WSSA0029 at $7,750 retail / ~$6,551 pre-owned. 35.1mm by 41.9mm, identical movement, the most popular Santos in the entire secondary market.
- For the dressier, thinner alternative: The Santos-Dumont LM on leather strap starting around $8,000 retail, or the new 2026 mesh bracelet references at €37,000-€49,000.
- For the sport-leaning expression: The WSSA0039 ADLC at $9,300 retail / ~$7,425 pre-owned. All-black coating on bezel, crown, and bracelet center links.
Everything else exists for specific reasons.
The Two Santos Collections
The Cartier catalog uses "Santos" to refer to two distinct watch families that share design DNA but serve very different roles.
| Collection | Design intent | Current sizing | Movement style |
|---|---|---|---|
| Santos de Cartier | Sport-leaning, daily wear, integrated bracelet | Medium 35.1mm / Large 39.8mm / Chronograph 47.5mm | Automatic |
| Santos-Dumont | Dressier, thinner, closer to 1904 original | LM 43.5mm x 31.4mm (7.3mm thin) | Manual wind |
The Santos de Cartier is the watch most buyers mean when they say "Santos." It is the brand's contemporary sport-luxury entry, sized for daily wear, with the integrated SmartLink/QuickSwitch bracelet system that lets owners swap straps without tools.
The Santos-Dumont is the connoisseur's alternative. Slimmer at 7.3mm thick, dressier, manually wound, closer in spirit to the original 1904 commission. Historically a strap watch. The 2026 W&W release changed that.
The Santos in 90 Seconds
The original early-20th-century Cartier Santos-Dumont. Designed in 1904 for the aviator who could not pull a pocket watch from his coat at altitude. Every modern Santos still carries the visible bezel screws and beaded crown from this design.
In 1904, Louis Cartier designed a wristwatch for his friend Alberto Santos-Dumont, the Brazilian aviation pioneer based in Paris. The brief was practical: Santos-Dumont needed to read time without taking his hands off his aircraft controls. Pocket watches did not work. The wristwatch as we know it did not yet exist.
Cartier's solution gave us several enduring design conventions. A square case with softly rounded corners. Visible bezel screws (eight of them, two at each corner). A beaded crown topped with a sapphire or ruby cabochon. Roman numerals on a silver dial. Sword-shaped hands.
The watch was commercially released to the public in 1911 and has remained continuously in production in some form ever since. That makes the Santos the only continuously produced shaped wristwatch in fine watchmaking that traces directly to the first decade of the wristwatch's existence.
The modern Santos de Cartier collection was redesigned in 2018 with the SmartLink bracelet adjustment system (no tools required to remove links) and the QuickSwitch strap attachment (swap bracelet for leather in seconds). Both have become signatures of the line.

Santos de Cartier Large WSSA0018: The Volume Reference
The Santos de Cartier Large WSSA0018. 39.8mm by 47.5mm, integrated SmartLink steel bracelet, calibre 1847 MC. The reference most pre-owned buyers actually want.
The WSSA0018 in steel is the Santos de Cartier reference that anchors the entire modern line. It launched in 2018 alongside the SmartLink/QuickSwitch redesign and has been the brand's volume play in the sport-luxury category since.
What it delivers
The case is 39.8mm by 47.5mm, which sounds large in linear dimensions but wears smaller than the numbers suggest because of the integrated bracelet (no traditional lugs) and the rectangular geometry. On a 7-inch wrist it sits closer to a 40mm round watch than a 47mm round watch.
The dial is silvered opaline with painted Roman numerals, blued steel sword hands, and a date window at 6 o'clock. The integrated H-link steel bracelet alternates polished and brushed surfaces and has the SmartLink mechanism on the inside that lets owners remove a half-link in 30 seconds without tools.
Movement is the in-house calibre 1847 MC, automatic, with anti-magnetic protection. 42-hour power reserve. Reliable, well-serviced, and built for daily use.
Specs and pricing
| Spec | Value |
|---|---|
| Reference | WSSA0018 |
| Case | 39.8mm x 47.5mm, polished and brushed steel |
| Dial | Silvered opaline, Roman numerals |
| Movement | Calibre 1847 MC, automatic, 42h reserve |
| Functions | Hours, minutes, seconds, date |
| Bracelet | Integrated steel SmartLink |
| Retail | $8,650 |
| Pre-owned | ~$6,867 (20.6% below retail) |
WatchCharts data shows the WSSA0018 averaging 21.5 days to sell on the secondary market in March 2026, which puts it in the top 16% of watches by velocity. The reference moves quickly because buyers know what it costs and what they are getting.
Santos de Cartier Medium WSSA0029: The Smaller Sibling
The Santos de Cartier Medium WSSA0029. 35.1mm by 41.9mm, the same calibre 1847 MC as the Large, and the most popular Santos in the entire secondary market according to WatchCharts data.
The WSSA0029 is the Santos most pre-owned buyers actually want, even though many shoppers come in asking about the Large. The case is 35.1mm by 41.9mm, which fits a wider range of wrists and reads more like a classical Cartier than a sport-luxury statement.
The movement is the same calibre 1847 MC as the Large. Same dial layout, same SmartLink bracelet, same QuickSwitch system. The only meaningful differences are dimensions and the steel content of the case.
WatchCharts ranks the WSSA0029 as the most popular Santos reference in the entire collection, with an average secondary market value of approximately $6,551 against $7,750 retail (15.5% below retail). The watch averages 11.5 days to sell, which is faster than 96% of watches WatchCharts tracks.
Why the Medium outperforms the Large secondary market
Two reasons. The 35.1mm dimensions match the proportions Cartier originally intended for the design. The 39.8mm Large case is a more modern proportion that suits the sport-luxury repositioning, however the Medium retains a stronger connection to the watch's design heritage.
The second reason is purely practical. The Medium fits a broader range of wrists. Couples and households where two people share watch interest often gravitate toward the Medium because it works on both wrist sizes.
For first-time Cartier buyers, the Medium is the safer purchase decision in pre-owned. Resale demand is consistently stronger.
Santos de Cartier Large WSSA0039 ADLC: The Sport Statement
The Santos de Cartier Large WSSA0039 ADLC. Steel case with black Amorphous Diamond Like Carbon coating on the bezel, crown, and bracelet center links. The most sport-leaning expression in the steel Santos catalog.
The WSSA0039 is Cartier's response to buyers who want the Santos shape with a more aggressive visual identity. The bezel, crown, and bracelet center links are coated in ADLC (Amorphous Diamond Like Carbon), a hardened black surface treatment that resists scratching better than DLC and reads matte rather than glossy.
The contrast between the polished steel outer bracelet links and the matte black ADLC center links is the signature visual element. The dial is matte black with painted markers and luminous hands, making this the only standard Santos with serious nighttime legibility.
Specs and pricing
| Spec | Value |
|---|---|
| Reference | WSSA0039 |
| Case | 39.8mm x 47.5mm, steel with ADLC black bezel/crown |
| Dial | Matte black with gilt Roman numerals |
| Movement | Calibre 1847 MC, automatic, 42h reserve |
| Functions | Hours, minutes, seconds, date |
| Bracelet | Steel with ADLC black center links |
| Retail | $9,300 |
| Pre-owned | ~$7,425 (20.2% below retail) |
WatchCharts data shows the WSSA0039 in the top 13% of Cartier Santos references by popularity. Buyers who want it tend to want it specifically rather than as a fallback option, which keeps the pre-owned market healthy.
Santos-Dumont LM 2026: The W&W Bracelet Release
The Santos-Dumont LM 2026 in yellow gold with gilded obsidian dial. The mesh bracelet (15 rows, 394 individual links each 1.15mm thick) inspired by Cartier's 1920s made-to-measure pieces is the news, not the dial.
At Watches and Wonders 2026, Cartier introduced three Santos-Dumont LM references fitted with a new flexible yellow gold or platinum mesh bracelet. Until this release, the Santos-Dumont had been almost exclusively a strap watch.
The bracelet is the news. The mesh is composed of 15 rows totaling 394 individual links, each 1.15mm thick, machined and finished at Cartier's Manufacture before being attached to the case and clasp. The construction is inspired by Cartier's made-to-measure metal bracelets from the 1920s.
Watch Collecting Lifestyle called the new bracelet "one of the most quietly persuasive updates the maison has fielded in years." The obsidian dial gets the headline attention. The bracelet is the structural advance.
The three references
| Reference | Material | Dial | Retail |
|---|---|---|---|
| WGSA0122 | 18k yellow gold | Silvered satin sunray | €37,000 |
| WGSA0123 | 18k yellow gold | Gilded obsidian (volcanic stone) | €38,900 |
| WGSA0124 | 950 platinum | Silvered satin sunray | €49,000 |
All three measure 43.5mm by 31.4mm with a 7.3mm thickness. The case is identical across references. The crown carries a blue sapphire cabochon on the yellow gold versions and a ruby cabochon on the platinum.
Movement is the calibre 430 MC (Piaget 430P base), manual wind, 38-hour power reserve, 18 jewels. Hand-wound 21,600 vph (3 Hz) movement that has been the workhorse of slim Cartier dress watches for years.
The gilded obsidian dial
The WGSA0123 obsidian dial is the visual subject. The stone is volcanic glass sourced from Mexico, cut to just 0.3mm thick and hand-polished. Microscopic air bubbles trapped in the polished stone create natural iridescent reflections, which means no two dials are identical.
Fratello's hands-on coverage describes the dial as "somewhere between black and very dark gray" with fine texture that catches light unpredictably. The polished yellow gold Roman numerals sit proudly above the dark stone surface.
This is the Santos-Dumont positioned for the modern collector tier. The reference that pairs Patek Calatrava-level pricing with Cartier's strongest current design statement.
Santos de Cartier Chronograph 2026: The Returning Sport Reference
The Santos de Cartier Chronograph was reintroduced at Watches and Wonders 2026 as a refresh of the 2020 reference. The case measures 47.5mm by 39.8mm by 11.6mm thick.
What changed from the 2020 reference
The 2020 Santos Chronograph used an unusual 9 o'clock chronograph pusher placement. The 2026 reference returns the pushers to conventional crown-side positions at 2 and 4 o'clock.
The dial layout changed from the previous configuration to a cleaner tricompax setup: small seconds at 6, 30-minute counter at 3, and 12-hour counter at 9. The subdial rims are framed in polished rhodium or yellow gold depending on the variant.
The dial center is satin-finished with a sunray effect at the periphery, separated by a guilloche knurled edge. The hour and minute hands are sword-shaped with green Super-LumiNova coating.
Reference structure
| Variant | Case | Bracelet/strap |
|---|---|---|
| Full steel | Steel | Steel SmartLink |
| Two-tone | Steel + yellow gold | Steel + yellow gold SmartLink |
| Full yellow gold | 18k yellow gold | Yellow gold SmartLink |
| Steel ADLC | Steel + black ADLC | Steel with ADLC black bracelet |
Movement is the in-house calibre 1904-CH MC, automatic, two-pusher chronograph, 47-hour power reserve, 10 bar water resistance.
WatchGuys projects retail for the steel variant in the $11,000-$13,000 range based on current Santos pricing structure. Official US pricing was not released at launch.
Vintage Santos Territory
The vintage Santos market spans more than a century of continuous production. References worth knowing:
- Original Santos-Dumont (1911-1920s). Very small cases (25mm-33mm), yellow gold or platinum, painted Roman numerals, silver dials. Period examples in collectible condition trade $15,000-$40,000+ depending on case material, dial, and provenance.
- Santos Galbée (1987-2010). The two-tone steel-and-gold Santos that defined the 1990s. 24mm-29mm cases, automatic or quartz, gold bezel with steel case and bracelet. Pre-owned runs $2,500-$5,500 in good condition.
- Santos Galbée XL (2005-2015). The larger version of the Galbée at 32mm-45mm, addressing the 2000s shift to bigger watches. Pre-owned runs $3,500-$6,500.
- Santos 100 (2004-2018). The transitional reference between the Galbée era and the modern 2018 Santos. 38mm-51mm cases in steel, two-tone, or yellow gold. Pre-owned runs $3,500-$7,500.
- Santos Demoiselle (2005-2015). The smaller, daintier Santos positioned for women. Pre-owned runs $2,000-$4,000.
- Santos Octagon / Santos Carrée (1980s vintage). The unusual variants worth tracking for enthusiasts. Pre-owned runs $3,000-$7,000.
If you want the most economically accessible vintage Santos, a Santos Galbée mid-size in two-tone is the move. If you want the most collectible, an original early-20th-century Santos-Dumont in original condition with original dial is the answer (and the price reflects it).
Pre-Owned Market Reality
WatchCharts tracks 161 distinct Santos references in active secondary market data. The overall average price across the line is approximately $7,000. The range runs from about $2,000 (vintage Santos Galbée references in average condition) to $42,000+ (precious metal limited editions, the new 2026 Santos-Dumont bracelet references).
In-production Santos references typically trade 22.3% below retail on the secondary market according to WatchCharts data. This is a notably tighter spread than most Patek references and reflects Cartier's allocation discipline. Most Santos references reach buyers without aggressive waiting lists, which keeps grey market premiums minimal.
The Medium WSSA0029 holds value best in the modern line at only 15.5% below retail, reflecting its position as the most-wanted Santos in active secondary inventory.
For buyers who want a Santos without retail wait times, the pre-owned market is the realistic path. A 2022-2024 WSSA0018 in box and papers runs $6,500-$7,200 through specialist dealers, against $8,650 retail. A WSSA0029 in similar condition runs $5,800-$6,800.
Which Santos Should You Buy?
First-time luxury buyer with a budget around $5,000-$7,000
A pre-owned WSSA0029 Medium at $5,800-$6,800 is the move. You get the most popular Santos in the catalog, in-house movement, full SmartLink bracelet with QuickSwitch, and a watch that fits a wide range of wrists. Resale demand is strong if you ever move it on.
A vintage Santos Galbée mid-size in two-tone for $2,500-$4,500 is the budget-friendly alternative if you want the Santos design at a lower entry point. The Galbée has authentic 1980s-90s character that the modern line cannot match.
Our Cartier Tank Buying Guide covers the rectangular dress watch alternative across the Cartier catalog if you want the brand's other signature shape.
Growing collector wanting their definitive sport-luxury Cartier
The WSSA0018 Large at $8,650 retail (or $6,500-$7,200 pre-owned) is the move. The 39.8mm case fits the contemporary sport-luxury aesthetic, the bracelet system is the best on any sport-luxury watch under $10,000, and the calibre 1847 MC is reliable enough to wear daily for years without concern.
If you want the more aggressive expression, the WSSA0039 ADLC at $9,300 retail adds visual presence and nighttime legibility without changing the underlying watch.
Growing collector adding a dressier Cartier
The Santos-Dumont LM on leather strap is the move at $8,000-$13,000 depending on metal. 7.3mm thin, hand-wound, slimmer proportions, closer to the original 1904 design intent.
This pairs especially well alongside a sport-luxury anchor like a Submariner or a Royal Oak. Worth reading in parallel with our Patek Calatrava Buying Guide and our Jaeger-LeCoultre Reverso Or Deco coverage for the broader dress watch context across the current high-end market.
Experienced collector chasing the modern Cartier flagship
The 2026 Santos-Dumont LM WGSA0123 in yellow gold with obsidian dial is the answer. €38,900 retail. The dial alone justifies the price (volcanic stone, no two examples identical) and the new mesh bracelet is the structural advance the model has waited a decade for.
For the platinum tier, the WGSA0124 at €49,000 carries the ruby cabochon crown and the silvered sunray dial. Both will be allocation-tight through 2027.
The full W&W 2026 release context is covered in our Lange Cabaret Tourbillon Honeygold at Villa d'Este coverage for the parallel high-end market story.
The collector building a true vintage focus
An original 1911-1920s Santos-Dumont in collectible condition is one of the few horological purchases that connects directly to the birth of the wristwatch. Expect $20,000+ for an example with original dial, original case, and credible provenance. This is auction territory rather than dealer inventory for the best examples.
FAQs
What is the difference between Santos de Cartier and Santos-Dumont?
The Santos de Cartier is the sport-luxury contemporary line with integrated steel or two-tone bracelets, automatic movements, and 35.1mm or 39.8mm cases. The Santos-Dumont is the dressier line with a slimmer 7.3mm profile, manually wound movements, traditional strap (or 2026's new metal mesh bracelet), and proportions closer to the 1904 original.
How much does a new Santos de Cartier cost?
Retail prices range from $7,750 for the Medium WSSA0029 in steel up to $9,300 for the Large WSSA0039 ADLC. Two-tone and yellow gold variants extend up to approximately $25,000+. The new 2026 Santos-Dumont in precious metals runs €37,000-€49,000.
What movement is in the modern Santos?
The Santos de Cartier (Medium and Large, all dial variants) uses the in-house calibre 1847 MC, an automatic movement with 42-hour reserve and anti-magnetic protection. The Santos Chronograph uses the calibre 1904-CH MC with 47-hour reserve. The Santos-Dumont LM uses the manually wound calibre 430 MC (Piaget 430P base) with 38-hour reserve.
What is the SmartLink bracelet system?
SmartLink is Cartier's tool-free bracelet adjustment system introduced with the 2018 Santos redesign. Owners can remove or add bracelet links in roughly 30 seconds without a watchmaker or specialized tools. The companion QuickSwitch system allows the entire bracelet to be removed and swapped for a leather strap (sold separately) in seconds.
Is the 2026 Santos-Dumont on bracelet better than on strap?
The bracelet versions reposition the Santos-Dumont as a more serious competitor to the Santos de Cartier in the precious metal segment, however the strap versions remain in production and serve different aesthetic goals. The bracelet adds presence and elevates the watch toward sport-luxury proportions. The strap keeps the watch in pure dress territory.
Can I buy a Santos pre-owned with confidence?
Yes. Santos references are well documented, widely serviced, and have strong reference number traceability. Look for box and papers, complete service history, original integrated bracelet (not aftermarket), and a dealer who provides authentication. Browse authenticated pre-owned Cartier at 5dwatches.com.
Will a Santos hold its value?
Modern Santos references trade approximately 22% below retail on average in the secondary market, with the Medium WSSA0029 holding value best at 15.5% below retail. We do not make investment-return claims at 5D Watches. Buy the watch because you want to wear it. The Santos is one of the most enduring designs in fine watchmaking, which makes it a low-risk addition to a collection across most reference choices.
What is the most popular Santos right now?
According to current WatchCharts data, the Santos de Cartier Medium WSSA0029 is the single most popular reference in the Santos family by trading volume on the secondary market. It sells faster than 96% of all watches WatchCharts tracks.
The Santos is the watch that started modern watchmaking. The fact that the design still works in 2026, more than a century later, with only modest structural updates to the case and bracelet, says everything about Louis Cartier's original brief.
