Innovations in endurance testing
the world's largest classification society for maritime safety dnv gl (formerly germanischer lloyd, hamburg), has been
testing our diving watches for pressure and water resistance since 2005. As part of dnv gl's official certification process,
our diving watches have been treated as part of diving equipment since 2006 and tested and certified in accordance
with european diving equipment standards. this is unparalleled in the watch industry. We have had selected pilot's
watches tested and certified to the technical standard for pilot watches (technischer standard fliegeruhren – testAf)
by Aachen university of Applied sciences since 2012. the testAf, the result of a research project at the initiative of sinn
spezialuhren, ensures that a pilot's watch meets all timekeeping requirements during flight operations in accordance with
visual and/or instrumental flight regulations and is suitable for professional use.
the temperature resistance technology keep mechanical watches performing at temperatures ranging from
− 45 °C to + 80 °C. this technology has proven its worth in the eZM 10 testAf, for example, used as part of the official
approvals procedure for Airbus helicopters (formerly eurocopter) eC 145 t2 high-performance helicopter. the
303 CrystAl is impressive proof of the functional reliability of our watches under the toughest climatic conditions.
equipped with temperature resistance technology, the chronograph passed the acid test at the yukon Quest, the
world's most demanding dogsled race. the 203 ArCtiC passed its Arctic endurance test on the wrist of extreme
diver Mario M. Weidner, withstanding all dives in the freezing cold waters of the Arctic ocean above 81 degrees
latitude. both watches were worn on top of protective clothing. the real test was in the extreme temperature
fluctuations between water and land – a test that the 303 CrystAl and the 203 ArCtiC passed with flying colours.
Prüfaufbau „Sicherheit und Kompatibilität mit
anderen instrumenten" im Rahmen der
tEStaF-Zertifizierung. Eine Fliegeruhr wie der
EZm 10 darf die avionik, wie zum beispiel den
notkompass, nicht beeinflussen.
lab test "safety and compatibility with other
instruments" as part of the testAf. for
example, a pilot's watch such as the eZM 10
must have no magnetic influence on the
emergency compass.
