Sinn - 144 St Diapal - Metal bracelet

These are a few of the characteristics of the 144 St Sa:

First the DIAPAL Technology – the lubricant-free anchor escapement. We use special combinations of materials that create no friction, even without lubrication, thus ensuring the long-term accuracy of the movement.

A second technology in the chronograph is a major innovation for a mechanical watch: thanks to Ar-Dehumidifying Technology, the movement is kept in an environment that is almost completely dry. This reduces aging and prevents the crystal from fogging when exposed to sudden cold, ensuring reliable functionality and accuracy for a longer period of time.

• Mechanical Movement
• • The information on the mechanical movement corresponds to the current production situation in Frankfurt am Main. Due to technical changes, it may happen in individual cases that stock items of our sales partners deviate from this information. (further Information)
