Equipped with a chronograph and second time zone display on 12-hour basis, the SINN 103 Ti UTC IFR is one of the world’s first pilot watches certified in accordance with DIN 8330. This automatic timepiece comes in a 41mm diameter case made of titanium in bead-blasted finish.

Uncompromisingly high standards must be met by aircraft and helicopter equipment in terms of functionality, reliability and safety. With DIN 8330, these uncompromisingly high standards are applied to wristwatches too. Various measures are taken to ensure that a DIN 8330-compliant pilot watch is not only a suitable all-round replacement for the on-board timekeeping instruments available to pilots, but is also capable of remaining unaffected by the physical stresses of flight, posing no risk potential for the crew or aircraft, and demonstrating compatibility with other on-board instruments. SINN has succeeded in meeting precisely these requirements for flight operation in accordance with instrument flight rules (IFR).

This is supported by the installation of SINN technologies: Ar-Dehumidifying Technology ensures greater functional reliability and freedom from fogging as well as functional reliability at a temperature range of –45 °C to +80 °C. Another special feature is the captive pilot’s bezel which is easy to operate even while wearing pilot gloves.
