THE WorLd'S FIrST,
TESTAF -CErTIFIEd TImEpIECE
In a research project lasting four years, the Faculty of Aerospace Technology
of the Aachen University of Applied Sciences (FH) and Sinn Spezialuhren
have developed a technical standard for pilots' watches (TESTAF). TESTAF
ensures that a pilot's watch meets all of the time measurement requirements
for flights operated under both visual flight rules (VFR) and instrumental flight
rules (IFR). The EZM 10 TESTAF, the 103 Ti TESTAF, 103 Ti UTC TESTAF and the
857 UTC TESTAF were the first SINN watches to undergo and pass the strict
test procedures.
For these watches to meet all the test criteria, we had to make various
adjustments to them. The watches then passed all of the tests with flying
colours. This means that they are suitable for professional use as a pilot's
watch – a fact that is documented by a certificate and the TESTAF seal of
quality on the face of the watch.
What are the distinguishing features of a professional pilot's watch? To provide
a universally valid answer to this question, it was necessary to formulate a
norm or standard, which did not exist for pilots' watches until today. And so in
2008, engineer Lothar Schmidt, managing director and owner of Sinn
Spezialuhren, took the initiative to close this research gap together with
engineering professor Frank janser of the Aachen University of Applied
Sciences.
