156.1 SZ01 156.030

The innovative character of the 156.1 model, is manifested with the in-house SZ01 chronograph movement, which is designed so that the timepiece has a jumping 60-minute stopwatch hand from the centre. The plus point: stop times can therefore be recorded more easily, quickly and accurately - a clear gain in terms of clear readability. This movement is integrated into a newly designed case with a screw-in back, which is aesthetically modelled on its historical predecessors with a 43 mm-diameter case. The 156.1 now has a sapphire crystal, which is more scratch-resistant than the acrylic glass used in the original model.

The pilot's bezel is captively connected to the case and can be rotated smoothly without detent, another innovation that we have implemented in this form for the first time in a SINN chronograph in series production. The TEGIMENT Technology of the pilot's bezel is also an important prerequisite for the application of the Black Hard Coating, which proves to be extremely durable as a result. In contrast to the historical models, the pilot's bezel has a luminescent fixed point as a striking symbol in the marking at twelve o'clock, so that the position of the set reference time can be clearly identified in the dark. The numbers as the hour and minute hands are also luminescent and therefore perfectly legible. 
The design philosophy for the 156.1 model is to continue tried and tested elements while utilising the potential for change. The result is a fascinating timepiece that is as historic as it is contemporary.
