Zenith Unveils a Skeletonized Chronomaster Sport with the El Primero 3600 SK

A skeletonized El Primero 3600 lets you see the high-beat chronograph movement in action.

The latest Chronomaster Sport in Zenith’s catalogue invites closer inspection. The reference is 03.3130.3600/01.M3130 (Zenith’s product page): a 41mm steel case, a scratch-resistant black ceramic bezel, and a gradient sapphire dial revealing the movement beneath.

The signature tricolour 3-6-9 counters remain, but the dial beneath them is skeletonized. The movement is the El Primero 3600 SK, and the SK suffix points to skeletonization rather than a standard 3600 viewed through a windowed dial. Zenith describes the watch as revealing the “openworked architecture of the El Primero 3600 SK.” The brand does not spell out that distinction any further, so read it as Zenith’s own framing.

What makes the view interesting is the beat. A balance running at 36,000 vph, or 5 Hz, divides each second finely enough for the chronograph train to resolve tenths, which is why a 3600 can carry a tenth-of-a-second display at all rather than the fifths of a slower calibre. Zenith counts 311 components in the movement, with roughly 60 hours of running time when fully wound.

Water resistance is 10 ATM. The watch is delivered on a steel bracelet with a micro-adjustable folding clasp, with a black rubber strap in the box.

Two caveats for collectors: Zenith lists neither a price nor a launch date on the page, and no independent coverage of this reference has surfaced, so everything here traces to the manufacturer alone.

Zenith's ZENCLASP Folding Clasp Adds Tool-Free Micro-Adjustment to the Chronomaster Sport Skeleton

Three years of development went into this bracelet clasp, and the details live on Zenith's product pages.

Most brands treat clasps as hardware, not engineering. Zenith’s product pages take a different view, calling the ZENCLASP a new folding clasp and “the result of three years of development.”

The key feature is micro-adjustment, the fine-tuning built into the clasp, not the coarse fit of adding or removing links. The system offers 2.5 mm increments across a 10 mm range, all adjustable on the wrist without tools.

Anyone who has wrestled with a screwdriver and a half-link will recognise the problem it solves. Half-links exist because full links overshoot, yet even then, a bracelet might feel tight in the morning and loose by evening. Ten millimetres of stepped adjustment covers much of that daily drift, all without removing the watch.

A quick point of vocabulary, since it gets used loosely: a deployant clasp is the hinged folding buckle that keeps a bracelet closed as one continuous loop, and the micro-adjustment is what happens inside it.

What the page does not say is worth flagging. There is no stated actuation method, no clasp material or finishing, and no patent or patent-pending language. Nor is any other collection named as carrying the system.

Where the ZENCLASP is confirmed is the Chronomaster Sport Skeleton, reference 03.3130.3600.01, listed with the El Primero 3600 SK movement. That is the reference to seek out at a retailer if you want to feel the increments for yourself.

MING's 37.06 Royal Selangor Pairs a Hand-Hammered Pewter Dial With Malaysian Craftsmanship

A Malaysian watchmaker teams up with a local pewter artisan for a dial unlike any other under sapphire.

On 30 July, MING unveiled the 37.06 Royal Selangor, a limited edition with a hand-hammered pewter dial crafted by Royal Selangor, the Malaysian pewter house that lends the watch its name. The case is grade-2 titanium, 38mm wide, 11.05mm thick, with a 44.73mm lug-to-lug measurement, fully brushed and rated to 100 meters. Both brands’ wordmarks are engraved on the back, and the specifications are listed on MING’s product page. At 35.9 grams, it’s light enough to forget it’s on the wrist.

Pewter, a tin-based alloy, is more common in decorative objects than watch dials. As WatchTime noted at launch, the hammered pewter dial is a rarity, and possibly a first, for a watch brand. Each dial is hand-hammered, so no two reflect light identically.

MING’s usual layering does the rest of the work. The indexes are engraved into the domed front sapphire and filled with Super-LumiNova X1, so they sit above the hammered surface rather than on it. Both crystals get double-sided anti-reflective coating. Inside is a Sellita SW300.M1 in a MING-specific execution, hours and minutes only, roughly 50 hours of reserve, with skeletonized rhodium-plated bridges over an anthracite-coated baseplate.

Eighty-eight pieces at CHF 5,000 before taxes, as Revolution reported, which also notes the full run is assembled in Kuala Lumpur. Royal Selangor boutiques had them first; limited stock reaches ming.watch from 6 August.

The draw here is provenance rather than complication: a watch brand working with a craft house from the city it comes from.

Audemars Piguet and Swatch Launch Royal Pop, a Collection of Eight Bioceramic Pocket Watches

Audemars Piguet and Swatch have announced Royal Pop, a collection of eight pocket watches that runs Royal Oak design codes through a Pop Art filter. AP’s news release, dated 13 May 2026, outlines the collaboration.

The unusual part? The corporate geometry. AP is privately held by the Audemars, Piguet and Wiederrecht families, and sits outside Swatch Group. Swatch has a reputation for collaborations (MoonSwatch with Omega, Scuba Fifty Fathoms with Blancpain), but partnering with an independent haute horlogerie house, meaning the top tier of finely finished mechanical watchmaking, is new.

The Royal Oak translation is instant. The eight-sided bezel is there, screws and all, and the dial wears the Petite Tapisserie pattern, the small waffle texture the originals made famous, here rendered in Swatch’s bioceramic rather than steel. Glazing on both sides of the case puts the movement on display: a hand-wound version of Swatch’s SISTEM51 carrying a Nivachron balance spring for magnetic resistance, a power reserve past 90 hours, and 15 patents. In place of a strap, a stitched calfskin cord lets each piece hang from the neck, ride in a pocket, or clip onto a bag.

The format matters. Moving those signatures off the wrist lets AP play without touching the Royal Oak itself.

AP will direct proceeds toward preserving watchmaking savoir-faire and supporting emerging talent. CEO Ilaria Resta described the aim as inviting “a broader audience including the younger generations to experience mechanical watchmaking differently.”

Sales run through select Swatch stores only. No price appears on AP’s page, and case dimensions and water resistance are not stated. Vogue reports sales opened 16 May amid heavy queues, which neither brand’s own page confirms.

H. Moser & Cie. Endeavour Minute Repeater Cylindrical Tourbillon Skeleton “Cosmic Rain”

H. Moser & Cie. has introduced the Cosmic Rain (ref. 1909-0501), the latest expression of its Endeavour Minute Repeater Cylindrical Tourbillon, a platform that first brought a minute repeater and flying tourbillon together on open display back in 2019 and gained a fully skeletonized treatment earlier this year. This new version dresses the movement in a celestial theme, with an aventurine subdial dotted with mother-of-pearl inlays shaped like shooting stars.

At its core is the manual-wind calibre HMC 909, entirely skeletonized so the dial-side hammers and gongs sit exposed on a single plane, alongside a one-minute flying tourbillon fitted with a cylindrical hairspring. The case itself is hollowed titanium, engineered to act as a resonance chamber that amplifies the repeater’s chime. Moser has limited the piece, reportedly to 20 examples, and pricing is available on request.

It’s a dense concentration of horological ambition: a chiming complication and a tourbillon both laid bare, wrapped in a case that doubles as an acoustic instrument. The Cosmic Rain pushes that engineering into more decorative territory, without losing sight of the mechanics that made the platform notable in the first place.

Breitling Top Time B01 Chronograph 41 – Tribute to Aston Martin DB5

A trio of cushion-cased chronographs channels the vintage cool of Bond’s favorite car.

Breitling has introduced a new capsule of three Top Time B01 Chronographs built as a tribute to the Aston Martin DB5, the car whose association with James Bond has made it one of the most recognizable automobiles in film history. The release continues Breitling’s long-running partnership with Aston Martin, this time filtering the DB5’s vintage character through the Top Time’s retro cushion-case design.

The steel reference, RB0178131B1X1, measures 41mm with Art Deco corner grooves and pump pushers, details that nod to the model’s 1960s roots. Inside sits Breitling’s in-house Manufacture Caliber 01, a self-winding chronograph movement with roughly 70 hours of power reserve. The steel version is priced at USD 18,600, with the trio’s other two references, in different case materials, priced separately.

Rather than launching an entirely new model line, Breitling is using the DB5 tribute to add fresh personality to the existing Top Time family, giving fans of both the watch and the car a tangible link between two icons of vintage design.
