Chronoswiss has extended its PULSE collection into travel-watch territory with the PULSE GMT Silver Guilloché (ref. CH-4223TM-GR), a 200-piece limited edition built in grade 5 titanium. Unveiled earlier in 2026 alongside a solid-gold sibling at Watches & Wonders, it represents the first dual-time execution of a case and bracelet architecture that debuted in 2025 as Chronoswiss’s original integrated-bracelet model.
Case Design and Proportions
The case measures 41mm in diameter, 13mm thick, and 46.27mm lug-to-lug, though “lugs” is something of a misnomer here. The end-links of the titanium bracelet mount directly into the middle case, creating a fully integrated structure rather than a conventional lug-and-strap arrangement. A curved sapphire crystal covers the dial, while a flat sapphire window sits in the screw-on caseback. Water resistance is rated to 100 meters, a notable step up from the 50-meter rating on the gold PULSE GMT models in the same family.
Finishing across the case and bracelet leans heavily toward brushed and sandblasted surfaces, with only limited high-polish accents breaking up the matte grey titanium. It’s a restrained approach to surface contrast that keeps the watch visually quiet despite its architectural complexity. Chronoswiss has also reworked some of its signature case details for this line: the onion-shaped crown, a long-standing brand hallmark, now sits inside flowing modern guards, and the coin-edge fluting typically found on Chronoswiss cases has been replaced with bolder, more geometric notches along the upper and lower case edges.
A Dial Layout Borrowed From the Tora
Rather than adopting the vertically-stacked regulator dial seen on the PULSE One models, the PULSE GMT looks back to the Chronoswiss Tora watches of the 1990s for its layout. Two independently adjustable hour hands sit on opposite sides of the dial: the hand at 3 o’clock runs on a conventional 12-hour display for local time, while the hand at 9 o’clock uses a 24-hour format to track home time and distinguish AM from PM. Both hour hands are set atop highly convex registers that rise into the dial’s curved surface, working alongside centrally mounted minute and seconds hands.
The dial itself is silver, with a guilloché-decorated central section framed by an outer ring finished in a dark sandblasted texture. The domed shape of the dial mirrors the convex registers built into it, and that curvature amplifies the visual depth of the guilloché pattern rather than flattening it under the crystal. All printed text on the dial is black, but metallic blue accents appear throughout: blued hands, a pair of blued screws at the dial’s center, and small blue indexes within the minute track. Each piece carries its individual limited-edition number, out of 200, printed at the bottom of the dial. Notably, there is no date display, which keeps the operating logic of the watch relatively simple despite its dual-time function.
Movement Architecture
Visible through the display caseback is the manufacture Caliber C.6002, an automatic movement running at 28,800vph (4 Hz) with a 55-hour power reserve. It carries 29 jewels and is decorated with Geneva stripes radiating outward from the center. The self-winding rotor is skeletonized and made from tungsten, and the movement’s components are given a ruthenium plating that ties visually into the watch’s grey color scheme. Standard conveniences include hacking seconds and manual winding via the crown, alongside the secondary time zone function that operates somewhat differently from typical GMT movement architecture, using the twin-hour-hand system rather than a single 24-hour GMT hand and rotating bezel.
Where It Sits in the PULSE GMT Family
The Silver Guilloché is one of three PULSE GMT variants currently offered, all limited editions. Its direct sibling, the Sky Gold, is cased in solid 18k gold with a blue sky-pattern enamel dial in a 50-piece run and retains the integrated bracelet. A third version pairs an 18k gold case with a silver frosted guilloché dial, also limited to 50 pieces, but departs from its siblings by mounting on a black rubber strap instead of an integrated bracelet.
Within that trio, the titanium Silver Guilloché stands out for its higher water resistance and its case material, which sets a more tool-oriented, travel-ready tone than the precious-metal versions. For a brand whose identity has long rested on traditional complications like the regulator dial, this dual-time execution of the PULSE line signals that Chronoswiss intends to keep pushing the collection’s engineering and dial-making vocabulary forward, rather than treating the 2025 integrated-bracelet debut as a one-off design exercise.
