Absolutely reliable functionality, perfect ergonomics, simple operation – these are a few of the characteristics of the 144 model series.
Watch lovers will also value these features of the 144 St DIAPAL. In terms of technology, this chronograph is the first in its series featuring DIAPAL Technology and a lubricant-free escapement. Sinn uses 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. And the display of a second time zone helps frequent flyers and world travelers keep track of the time at a glance.
