Sinn 903 ST BE II 903.091

The 903 ST BE II navigation chronograph, available as a standard model with a deep‑blue dial, has been technically elevated to a unique level. The function‑rich dial gives this navigation chronograph in our range a tradition that has lasted for decades. Using the slide‑rule ring with a logarithmic scale, one can perform calculations for determining times, distances or fuel consumption. Notably, the hand‑set indices, the 12‑hour marker and the hour and minute hands use hybrid‑ceramic lume elements. By integrating the luminous pigments into the respective hybrid‑ceramic parts, a high concentration of luminescent material is achieved, resulting in extreme brightness and perfect legibility in darkness. Especially with the new case design of the 903 ST BE II, the high innovative power of our company is demonstrated once again. This case features a galvanically silver‑plated rotating ring that operates directly and smoothly on the outer diameter of the watch. This construction gives the watch an impressive water resistance of 20 bar.
