Sinn 403.050 description
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. Currently the most modern and precise chronometer quartz movement on the market, keeps the UX’s time, more than fulfilling the especially strict Swiss chronometer norms for quartz movements.
The temperature-stabilized 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.
