Advancements in endurance testing
take, for example, the absolutely condensation-free, anti-reflective, German submarine steel diving
watch – made possible by hYdro technology. other examples include a chronometer chronograph
fashioned from a 22-carat gold alloy that is as hard as stainless steel and a chronometer with a
magnetic resistance of up to 80,000 a/m. there are also watches with a clockwork mechanism optimally
protected from aging by an inert gas and integrated dehumidifying capsule. the list would not be
complete without mentioning the development of mission timers (einsatzzeitmesser or eZM in German)
for firefighters, for special police units and border patrol guards as well as temperature resistance
technology to keep mechanical watches performing at temperatures ranging from − 45 °C to + 80 °C.
this technology has proven its worth in the eZM 10 testaf model, for example, used as part of the
official approvals procedure for airbus helicopters (formerly eurocopter) eC 145 t2 high-performance
helicopter. hot and cold climate tests and high-altitude experiments were carried out in the deserts of
the usa, the rocky Mountains and the frozen wastes of Canada. the watch was worn unprotected,
outside the pilot's overall, during cold climate tests at temperatures reaching − 45 °C.
Die Schneewalze des hubschraubers birgt das risiko eines
Orientierungsverlustes für den Piloten.
the snow swirled up by the downwash can make the pilot
completely lose his orientation.
