Sinn Diving Watch UX EZM 2B

$3,745.00 CAD

Perfect legibility even under the most adverse of conditions, the largest dial possible, and a bezel that won’t come off or pitch to one side: these are challenges that Sinn’s engineers have fulfilled with Model UX.
The case filled with a special oil makes the watch legible from every angle, even under water. This oil filling keeps the case water-resistant to any reachable diving depth.

The temperature-stabilised high-precision movement is powered by a lithium ion battery, which not only has an exceptionally long life, but can also supply electricity at minus temperatures of up to -25° Celsius.
