Sinn - 104 St Sa I A

This series has a clearly structured look which makes it easy to read the time, date and day of the week: these are classic pilot watches in the time-honoured SINN tradition. You can see why they are among the best-loved timepieces we produce.

With the 104 St Sa I B we offer a dark blue dial, finished off with an elegant sunburst decoration. This traditional ornamental grinding on the dial reflects different nuances of light.

Sapphire crystal is used for the crystal on the front and the transparent back. The pilot’s bezel can be rotated in both directions. With minute ratcheting. It is captive in the polished stainless steel case and has a luminous triangular key marker.

The watch is pressure-resistant up to 20 bar and resistant to low pressure.
