Ultra-Chron
The Ultra-Chron combines modern engineering with a nod to historical diving watches. Its robust design is complemented by a distinctive rotating bezel, offering both style and functionality.
Jump from the 37mm Classic to this 43mm Ultra-Chron and the water resistance leaps from 50m to 300m — the same high-frequency lineage now built into an actual dive-capable case rather than a dress-sport one. Black dial, steel bracelet, no date window to interrupt the symmetry, which is the right call on a tool watch this size. It's a useful reminder that 'Ultra-Chron' on the dial doesn't tell you much on its own — the two references I've catalogued from this line sit at opposite ends of my proportions and purpose axes, and treating them as interchangeable would be a mistake.
