For decades, Panerai's relationship with the cushion case has been a one-way street. The brand built its modern identity around the 1950s reference 6152/1, the 47mm Marina Militare military dive watch supplied to Italian Navy frogmen, and that 47mm geometry has stayed in the catalog mostly untouched ever since.
The problem is that 47mm is a hard sell on most modern wrists. The Luminor 8 Giorni and the historical reissues kept the 47mm proportion sacred, while the rest of the lineup pivoted toward 44mm and below. Heritage on one shelf, wearability on another.
The 2026 PAM01731 collapses that gap. For the first time, Panerai has translated the 6152/1 cushion architecture into a 44mm case. The crown protector bridge, the cushion middle case geometry, the domed crystal, and the sandwich dial all stay. The diameter drops 3mm and the watch becomes wearable for buyers who couldn't get there before.
This is a working dealer's read on what the PAM01731 actually is, why the 44mm 6152/1 reissue matters, and how to think about it against the rest of the Panerai catalog.

The Short Answer
The Panerai Luminor PAM01731 is a 44mm steel reissue of the 1960s reference 6152/1 cushion case, launched at Watches and Wonders 2026 alongside its left-handed Destro sibling PAM01732. Both watches share a 44mm polished steel cushion case, 300m water resistance, sandwich dial construction, domed sapphire crystal mimicking vintage Perspex, and the in-house P.6000 hand-wound caliber with a 3-day power reserve. Retail is EUR 8,900 (CHF 7,800). The PAM01731 carries a tobacco-gradient dial with small seconds at 9 o'clock; the PAM01732 Destro inverts the case (crown bridge on the left at 9 o'clock) and carries a matte blue gradient dial with hours and minutes only. Both are in regular production, available from April 2026.
Why the 6152/1 Matters: The Original Marina Militare Dive Watch
The reference 6152/1 was not a civilian product. Panerai built it in the 1950s and 1960s as professional dive equipment for the Italian Navy's combat frogmen, incursori. The specifications were dictated by the Navy: exceptional legibility in low light, durability, water resistance, and an extended power reserve. Civilian sales weren't part of the program until much later.
The 6152/1 architecture established what would become Panerai's permanent design vocabulary. According to Monochrome's coverage of the new release, the original carried:
- A 47mm cushion-shaped steel case with solid lugs machined from a single block
- A reinforced screw-down crown protected by the patented crown-protecting bridge
- An outsourced manual-winding movement (Rolex calibers in earlier examples, Angelus 8-day calibers in later production)
- A solid screw-down caseback (no display window, durability over visual access)
- Sandwich dial construction with cut-out luminous numerals over a continuous lume disc
- A domed Perspex crystal (acrylic, not sapphire) for legibility and impact resistance
The crown protector bridge is the detail that defines the line. It's a hinged metal lever that locks down on the crown, providing both water sealing and protection against accidental knocks during diving operations. Modern crown gaskets and screw-down crowns achieve the same water resistance without the bridge, but removing the bridge would erase the visual identity of the brand. Every modern Luminor and Submersible carries it.
The vintage 6152/1 in 47mm. Aged tritium luminous material, domed Perspex crystal, integral solid lugs. The reference that the modern PAM01731 directly translates.
The 6152/1 served the Italian Navy through the 1960s and was effectively discontinued by the 1980s. Original examples in honest military-issued condition trade well into six figures at auction. Civilian-issued pieces from the same era trade lower but are still scarce. The 6152/1 is the watch every Panerai release for the past 30 years has been measured against.
What the PAM01731 Actually Changes
The cushion case translation from 47mm to 44mm is the headline. Three millimeters does more for wearability than the spec change suggests. A 47mm cushion case sits roughly equivalent to a 49mm round case on most wrists; a 44mm cushion sits closer to a 42mm round case. For a buyer with a 7-inch wrist who finds the 47mm Luminor visually too aggressive, the 44mm 6152/1 reissue is the first time the original architecture has been on the table.
What stays from the 6152/1:
- Cushion middle case geometry. Polished bezel with brushed crown-protecting bridge for surface contrast.
- Domed sapphire crystal. Recreates the visual depth of the original Perspex without the impact-resistance compromises of acrylic.
- Sandwich dial construction. Two-plate dial with cut-out numerals revealing beige Super-LumiNova through the cut-outs.
- Vintage pencil hands. Thin, tapered, period-correct.
- Beige aged Super-LumiNova. Mimics the warm cream tone of aged tritium without the radiation.
- 300m water resistance. Significant achievement for a vintage-styled construction. The 6152/1 originals tested to similar depths.
What's new:
- 44mm case diameter (from 47mm).
- Sapphire display caseback. Original was solid steel, the modern reissue shows the P.6000 movement.
- In-house P.6000 caliber. Hand-wound, 3-day power reserve from a single barrel, 19 jewels, 21,600 vph. Not the outsourced Rolex or Angelus base of the 1960s original.
- Modern strap quick-release system. Comes with a brown calfskin leather strap and an additional rubber strap.
The technical execution sits at the strict heritage end of the 2026 Panerai catalog. No date window. No GMT complication. No automatic winding. The watch is a deliberate exercise in what the original 6152/1 was: hours, minutes, small seconds, hand-wound, and capable of going underwater.
The PAM01732 Destro: A Niche Variant Worth Understanding
The Destro is Italian for "right-hand side," and the variant has a specific origin. In the 1960s, Italian Navy frogmen wore diving instruments (depth gauge, compass) on their left wrist and the watch on their right wrist. With the watch on the right, the standard right-side crown would dig into the back of the hand. Panerai supplied a small number of Destro variants with the crown protector bridge moved to the left side of the case at 9 o'clock, allowing the watch to be worn on the right wrist without crown interference.
The PAM01732 Destro inverts the case. Crown protector bridge sits at 9 o'clock instead of 3, and the dial is a matte blue gradient with hours and minutes only.
The PAM01732 carries the Destro architecture in the new 44mm 6152/1 case. The dial drops the small seconds subdial (hours and minutes only) and switches to a matte blue gradient that reads cooler and more contemporary than the tobacco PAM01731. According to aBlogtoWatch's release coverage, some modern collectors prefer Destro variants on the left wrist (the conventional position), reasoning that a crown that won't be touched after the time is set might as well sit out of the way.
The Destro is a low-volume preference within the catalog. Most buyers will gravitate to the standard PAM01731. The PAM01732 exists for buyers who want the historical specificity and the slightly more unusual silhouette.
The P.6000 Movement: What You're Getting
Panerai's P.6000 is a hand-wound in-house caliber introduced in the 2010s and used across the brand's simpler tool-watch references. The technical specs are conservative by design.
| Spec | Detail |
|---|---|
| Type | Hand-wound mechanical |
| Caliber size | 15.5 lignes, 4.5mm thick |
| Components | 110 |
| Jewels | 19 |
| Beat rate | 21,600 vph (3 Hz) |
| Power reserve | 3 days (single barrel) |
| Anti-shock | Incabloc |
| Functions (PAM01731) | Hours, minutes, small seconds, stop-seconds (hacking) |
| Functions (PAM01732) | Hours, minutes, stop-seconds (hacking) |
The 3-day power reserve from a single mainspring barrel is the technical decision that pulls this caliber back to mid-tier. Panerai's P.5000 in the 8 Giorni references uses two barrels for an 8-day reserve. The new P.2031/S in the 2026 Luminor 31 Giorni uses four barrels for a 31-day reserve. The P.6000's single barrel is the budget-conscious choice that keeps retail at EUR 8,900 instead of climbing into Goldtech and complication territory.
For a 3-Hz hand-wound movement at this price point, the P.6000 is honest. The hacking feature is welcome (lets you sync the watch precisely when winding), the 3-day reserve covers a long weekend off the wrist, and the in-house designation matters for buyers who care about manufacturing depth. According to Revolution's W&W 2026 coverage, the P.6000 is positioned as Panerai's accessible hand-wound calibre and the entry point into the brand's manufacture lineup.

How the PAM01731 Compares to the Rest of the 2026 W&W Lineup
The PAM01731 doesn't exist in isolation. Panerai launched five new Luminor references at W&W 2026, and the PAM01731 sits at the entry point of the heritage tier.
| Reference | Case | Dial | Caliber | Power Reserve | Retail (EUR) |
|---|---|---|---|---|---|
| PAM01731 | 44mm steel | Tobacco gradient | P.6000 | 3 days | 8,900 |
| PAM01732 Destro | 44mm steel | Blue gradient | P.6000 | 3 days | 8,900 |
| PAM01733 Brunito 8 Giorni | 44mm Brunito steel | Anthracite circular brushed | P.5000 | 8 days | ~10,800 |
| PAM01735 | 47mm steel | Tropical ivory/brown gradient | P.5000 | 8 days | TBA |
| PAM01631 Luminor 31 Giorni | 44mm Goldtech | Skeletonized | P.2031/S | 31 days | ~85,000 |
The PAM01731 is the most accessible of the heritage releases at EUR 8,900. The PAM01735 (still 47mm, tropical aged dial, 8-day reserve) is for buyers who want the full-size original geometry. The Brunito PAM01733 with its hand-distressed black PVD finish and 8-day movement is the visual standout. The 31 Giorni in Goldtech is the technical halo at the top.
The 47mm PAM01735 keeps the original 6152/1 size with a tropical aged dial. For buyers who want full-size historical correctness, this is the W&W 2026 release.
For most buyers, the PAM01731 is the sensible heritage choice. It hits the cushion case translation, carries the in-house movement, and stops short of the price climb that comes with the 8-day calibers and precious metal cases above it.
What This Means for the Pre-Owned Panerai Market
The PAM01731 launched in April 2026, so secondary market data is thin and will stay that way for at least 12 months. Three predictions worth tracking:
- The PAM01731 will likely trade close to retail or at modest discounts in the first year. The combination of a fresh release, in-house movement, and 6152/1 design lineage typically supports value during the initial sell-through period. Heritage-aligned Panerai references have held up better than the brand's wider catalog historically.
- The PAM01732 Destro will trade at a small premium to the PAM01731 over time. The Destro variant is produced in lower volumes, the left-side crown bridge is a niche preference, and collectors who want the variant will pay slightly more for it on the secondary market.
- The PAM01731 will not change Panerai's broader pre-owned dynamic. The wider catalog still trades 25 to 40 percent below retail across non-limited references, and one new reissue won't reverse the structural softness we covered in our Panerai Luminor primer.
For broader Panerai pre-owned context, see our Luminor decoded primer. The PAM01731 sits at the strongest end of the new-release pricing band, but the broader market dynamics covered there still apply.
The PAM01731 on wrist. The 44mm cushion case sits closer to a 42mm round watch in actual wear. The 3mm diameter reduction from 47mm is the wearability story.
Who Should Actually Buy One
For a first Panerai with heritage lineage. The PAM01731 in tobacco at EUR 8,900 is the cleanest entry into the brand's military-roots story without crossing into 47mm or 8-day calibres. The in-house P.6000 covers the manufacture argument, the cushion case at 44mm is wearable, and the tobacco dial is the most distinctive new color in the modern Panerai palette.
For a collection completeness piece. The PAM01732 Destro at the same EUR 8,900 retail is the variant with the better long-term collector positioning. Lower production volume, niche left-crown architecture, and the historical specificity that matches what Italian Navy frogmen actually wore.
For full-size 6152/1 architecture. Skip the PAM01731 and look at the PAM01735 in 47mm. Same vintage spirit, full historical proportions, tropical aged dial, and the 8-day P.5000 caliber. Pricing not yet confirmed but expect a premium over the 44mm references.
For someone who already owns multiple Panerais. The PAM01731 may not add enough to an existing rotation. The cushion case translation is the defining feature, and if you already own a Luminor Marina at 44mm, the dial color and case shape distinction may not justify the spend.
The Honest Take
The PAM01731 is the most considered Panerai release in years. The 44mm 6152/1 translation answers a real wearability problem that the 47mm originals couldn't solve. The execution is restrained: tobacco dial, vintage pencil hands, sandwich construction, in-house hand-wound caliber, no unnecessary complications. Everything about the watch points back to what the 6152/1 was rather than what 2026 design language wants it to be.
The criticism worth flagging: the P.6000's 3-day single-barrel power reserve is the entry-level expression of the modern Panerai movement family. Buyers comparing the PAM01731 to the PAM01733 Brunito at slightly higher retail will find the 8-day P.5000 a meaningful technical step up. For buyers who want the most movement for the money in the new lineup, the PAM01733 is the better technical buy.
For buyers who want the cleanest 6152/1 expression at the most accessible price, the PAM01731 is the right watch. EUR 8,900 puts a 44mm Marina Militare reissue with sandwich dial, 300m water resistance, and an in-house hand-wound caliber on the table for the first time. The execution earns the price.
