Nereide GMT Ceratung™ is the first watch to use both Ceramic and Tungsten in the same bezel insert. Scoring 8 and 9 respectively on the Mohs scale, these materials are unbelievably resistant, twice as much as steel (Mohs 4), and are practically unscratchable.

Designed for frequent travelers or those who work across multiple time zones, this bezel allows you to effortlessly track the time in a second location. The 24 clicks represents the hours of the day, enabling precise and immediate alignment. Its bidirectional rotation makes the adjustment even quicker, eliminating unnecessary steps—just a few moments are all it takes to adapt to a new time zone, wherever you are in the world.

Produced in Soprod SA facilities in Switzerland, the V3290 is a GMT movement based on the caliber C125. The elaborated skeletonized shape of the new rhodium-plated rotor is designed to emphasize even more the details of the movement, and juxtaposes to the essential sandblasted decoration of the bridges. This peculiar combination makes the V3290 aesthetics modern and refined.
