The SN0121TF is a Watchdives collaboration model developed with San Martin, combining Watchdives’ product direction with San Martin’s manufacturing and finishing.

Designed as a compact titanium GMT watch for travel and everyday wear, it is powered by the Hangzhou 6465 automatic GMT movement, running at 28,800 vph for a smooth, high-beat sweep.

The 39mm Grade 5 titanium case keeps the watch lightweight on the wrist, while the Grade 2 titanium bracelet brings the total weight to approximately 104g. A sapphire crystal with AR coating, 24-click bidirectional ceramic GMT bezel, BGW9 lume and 300m water resistance round out the specification.

With a 47mm lug-to-lug length and 13.1mm thickness, the SN0121TF offers a balanced fit without feeling oversized, making it a practical option for anyone looking for a lightweight automatic GMT watch with strong everyday usability.
