203 ARKTIS
The 203 ARKTIS chronograph is our first diving watch to feature Temperature Resistance Technology. This means that it is guaranteed to run and function reliably even at exceptionally low temperatures.
This watch passed its Arctic endurance test on the wrist of extreme diver Mario M. Weidner – with flying colours! The 203 ARKTIS survived not only all the dives in the icy water of the Arctic Ocean, also sessions in the sauna on-board of the research vessel. However, the true test of the watch's quality lay in coping with the extreme temperature fluctuations between those found in the water (freezing point) and those on land (up to –25 °C) which represents a real challenge for a watch worn outside a thermal diving suit.
Each individual piece the diving watch 203 ARKTIS undergoes function testing by Sinn at a temperature range between –45°C and +80°C, which is very unusual for mechanical watches.
