Inventive talent and patents
Take, for instance, the absolutely condensation-free and anti-reflective diver's
watch made of stainless steel — designed with HYDRO
technology. Other
®
examples include a chronometer chronograph fashioned from a 22-carat gold
alloy, which is as hard as stainless steel, and a chronometer whose resistance to
magnetic interference is 20 times greater than normal. Or those models filled with
inert gases and featuring an integrated dehumidifying capsule to counteract
moisture infiltration and the ageing of the watch movement. This list would not
be complete without mentioning the development of socalled Einsatzzeitmesser
(EZM
) watches for special police units and border guards, and the lubrication
®
and tolerance technology that allows mechanical watches to perform at
temperatures ranging from –45°C to +80°C. Model 303 KRISTALL
passed the fire
®
and ice test during the 1998 Yukon Quest sledgedog race that crosses the icy
wilderness of Canada and Alaska, where temperatures are known to plunge
to –40°C. The watch was strapped to the arm of some of the participants on top
of their protective clothing. This was followed in 1999 by the ARKTIS
model 203.

This diver's chronograph passed its field test in the North Polar Sea with flying
colours.
