Chronograph ANN0631
Ref.: ANN0631
The Andersmann Chronograph ANN0631 is a tough, no-nonsense dive watch. Its 44mm Grade 2 titanium case has a bead-blasted finish with a DLC-coated middle layer for extra durability. The black sandwich dial, with yellow accents and luminous markers, keeps things legible. Powered by the Swiss ETA A07.211 automatic movement, it offers a 46-hour power reserve, 300m water resistance, and a comfortable FKM rubber strap.
