Sinn Watch 103 Ti UTC Testaf Leather. Pilot watches are fitted with special functions and features. In the 20th century, they were the main means of time measurement in aviation. And to this day, they serve as an additional safety system in many aircraft. It is your task to plan and carry out the necessary flight manoeuvres using a pilot watch. The 103 Ti UTC TESTAF can provide precisely this. 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. TESTAF guarantees that the 103 Ti UTC 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. This means, for example, that the 103 Ti UTC 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 UTC 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 +8 ?C. The pilots bezel with minute ratcheting has a captive connection to the case. The 103 Ti UTC TESTAF provides an additional time measurement element in the form of a second time zone on a 12 hour basis. This has proven to be very useful in aviation, as the flight times are documented in UTC. If the pilot adjusts the second time zone display accordingly, they can view the correct UTC on the dial at a glance without having to recalculate.
