It’s obvious at a glance what the 103 model series was created for: uncompromising functionality. They are designed to resemble cockpit instruments, in keeping with Sinn’s company tradition. After all, the first watches Sinn produced were mechanical aviation clocks for professional use. The patented technologies they have developed over the years are now also part of these classic SINN watches. For example, the 103 Ti DIAPAL and 103 St DIAPAL models feature a lubricant-free escapement (DIAPAL Technology).
Sinn uses special combinations of materials that create no friction, even without lubrication, thus ensuring the long-term accuracy of the movement. To perfect the technical design, both models are equipped with Ar-Dehumidifying Technology. The movement is embedded in an environment that is almost completely dry. This reduces aging and prevents the crystal from fogging when exposed to sudden cold, and ensures reliable functionality and accuracy for a longer period of time. If you are looking for a traditional pilot’s chronograph equipped with a second time zone and the latest technology, you will appreciate these models.
