A limited edition of just 500 special anniversary chronographs is presented in
March 2011 to commemorate 50 years of SINN. SINN develops its own SZ05 movement
for this watch. The anniversary chronograph sells out within three weeks.
The central stop minute hand – the SZ01. Development started in 2003. It was
based on the clearly readable and well-known Lemania 5100. The SZ01 chronograph
movement is designed so that any watch using it can also feature a
centre-mounted, jump 60-minute stopwatch. This allows stop times to be taken
even more simply, quickly and accurately.
The EZM 10, a Mission Timer made from high-strength titanium, is the result of
many years of development work on the SZ01.
2012 - TESTAF presentation
Aachen University of Applied Sciences and Sinn Spezialuhren present the first
technical standard for pilot watches (Technischer Standard Fliegeruhren – TESTAF)
on 19 July 2012 at the German headquarters of the leading helicopter and
aircraft component manufacturer Airbus Helicopters (formerly Eurocopter) in
Donauwörth. The development of this technical standard breaks new ground, as
there was previously no suitable standard for pilot watches. TESTAF, the result
of a research project at the initiative of Sinn Spezialuhren, ensures that a
pilot watch meets all time measurement requirements during flight operations in
accordance with visual and instrument flight regulations.
Sinn Spezialuhren presents the first watches certified according to TESTAF
standards in the world. In the first series of trials, three SINN models meet
the requirements. Various adjustments need to be made for these three watches to
meet all the testing criteria. Subsequently, the EZM 10 TESTAF, 103 Ti UTC
TESTAF and 103 Ti TESTAF passed all tests successfully. In addition to the
certificate, this is proven by the TESTAF quality seal on the dial.
2013 - SINN 857 UTC TESTAF: the basis for a new standard in pilot watches
At the request of Sinn Spezialuhren, the German Institute for Standardisation is
developing the first standard for pilot watches in line with German Industry
Standard DIN 8306 for diving watches. This new draft DIN 8330 is based on the
technical standard for pilot watches (Technischer Standard Fliegeruhren – TESTAF),
which will continue to be valid for testing and certifying pilot watches.
