What is it that represents a professional pilot watch? Which in-flight needs of the pilot must it meet? Which features are essential? The 103 Ti TESTAF provides the answers to these questions. This is because it was tested and certified by Aachen University of Applied Sciences in accordance with the technical standard for pilot watches (Technischer Standard Fliegeruhren, TESTAF). This is documented by a certificate and the TESTAF quality seal on the dial.

TESAF guarantees that the 103 Ti TESTAF fulfil all requirements of time measurement during flight operations, both under visual flight rules (VFR) and instrument flight rules (IFR), and that it is suitable for professional use as a pilot watch. In this sense, the 103 Ti TESTAF serves as an additional safety system for planning and carrying out necessary flight manoeuvres using a pilot watch. This means, for example, that the 103 Ti TESTAF ensures the elapsed times (second stop and minute stop) are perfectly readable, even at night. It thus fulfils an essential condition for IFR certification. 

The 103 Ti TESTAF safety concept is rounded off with SINN technologies such as Ar-Dehumidifying Technology for increased reliability and freedom from fogging, as well as functional reliability in a temperature range of –45°C to +80°C. The pilot’s bezel with minute ratcheting has a captive connection to the case.
