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 our company tradition. After all, the first watches we produced were mechanical aviation clocks for professional use. The patented technologies we have developed over the years are now also part of this classic Sinn chronograph.
The 103 Ti DIAPAL with its bead-blasted titanium case features a lubricant-free escapement (DIAPAL Technology). We use 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, this model is 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, a captive pilot's bezel and the latest technology, you will appreciate this model.
