Chronoswiss has been steadily reshaping its visual language with the Pulse collection, and the latest GMT makes that shift feel more deliberate.
The Pulse GMT Frosted Guilloché Gold takes the brand’s familiar codes, including the onion crown, coin-edge detailing and layered dial architecture, and places them inside a warmer, more contemporary precious-metal format.
Limited to 50 pieces, it pairs an 18k red gold case with a black rubber strap, giving the watch a more casual edge than the bracelet-equipped Pulse GMT models that came before it.
At a glance
- Chronoswiss has introduced the Pulse GMT Frosted Guilloché Gold as a 50-piece limited edition.
- The watch combines a 41mm 18k 5N red gold case with a frosted hand-guilloché dial and dual-time display.
- It is priced at CHF 42,000 or EUR 46,500 and is fitted with a newly developed black rubber strap.
A warmer take on the Pulse case
The Pulse line marked a clear move into more contemporary territory for Chronoswiss, and this edition leans into that direction without abandoning the brand’s established identity.
The case keeps the collection’s 26-part construction, with a 41mm diameter, 13mm thickness and 46.27mm lug-to-lug measurement.
Its 18k 5N red gold casework mixes satin brushing, sandblasting and polished accents, giving the precious metal more texture than a conventional high-polish dress watch case.
The partially knurled bezel and recessed onion crown remain recognisably Chronoswiss, while subtle crown guards and the integrated-style strap architecture make the silhouette feel less traditional.
A double-coated anti-reflective sapphire crystal sits over the dial, while the screw-down case back has its own sapphire window for viewing the movement.
Water resistance is rated to 50 metres, which suits the watch’s sport-luxury positioning rather than suggesting any serious aquatic brief.
Frosted guilloché and a split GMT layout
The dial is where the Pulse GMT Frosted Guilloché Gold becomes most distinctly Chronoswiss.
Rather than flattening the display into a conventional travel-watch format, the brand uses a multi-level construction with a hand-guilloché centre, domed displays, frosted sandblasted surfaces and nickel galvanic coatings.
Blue is used as the key contrast against the silver-toned frosted dial, appearing on the polished PVD-coated applied indices, blued steel Pyramid hands and printed markings.
A pair of blued screws at the centre adds a slightly technical note, reinforcing the engineered feel of the layout.
The GMT system remains straightforward once understood.
Local time is shown through the 12-hour subdial at 3 o’clock, while home time is indicated by a 24-hour disc at 9 o’clock.
Central minutes and seconds link the two displays, giving the watch a balanced left-right composition that avoids crowding the dial.
The C.6002 automatic movement
Inside is the Chronoswiss calibre C.6002, an automatic movement developed with La Joux-Perret.
It runs at 28,800 vibrations per hour, uses 29 jewels and offers a 55-hour power reserve.
Through the sapphire case back, the movement shows a skeletonised tungsten rotor, Geneva-striped ruthenium-plated bridges and polished components.
It’s a modern presentation for a brand that still places visible mechanical architecture at the centre of the experience.
Rubber changes the character
Unlike earlier Pulse GMT references, this limited edition is not fitted to an integrated bracelet.
Instead, Chronoswiss uses a newly developed black rubber strap, secured with a black DLC-coated and 5N gold Chronoclasp folding clasp.
The change matters because it shifts the watch away from the full precious-metal bracelet language and makes the red gold case feel more relaxed.
It’s still a high-end GMT, but the rubber strap gives it a less formal rhythm and should appeal to collectors who prefer their gold watches with a sharper, contemporary attitude.
