Sinn caliber SZ01

The SZ01 movement is based on the successful Valjoux 7750 and has been specially developed by SINN. The development work began back in 2003. The main priority in undertaking the redesign was to make the chronograph functions significantly easier to read off. Which is why Sinn attached so much importance to finding a first-class technical solution to mounting the jump 60-minute stopwatch hand in the centre of the dial. This allows users to take accurate stop times even more quickly and simply. The clarity and distinct readability of this chronograph stem from the design of the well-known Lemania 5100 movement. Sinn's redesign enhances the readability in two ways: firstly, 60 minutes are now counted in one sweep of the hand instead of the usual 30 minutes, and secondly, the minute stop scale covers the entire diameter of the dial.
