Since 1996, under the name sdw® Swiss Diver Watches, we have been manufacturing the world’s first diving watches which are completely filled with a special liquid apart from a small air bubble. This technology (patented 1997*), the Hyperbar® Deep Diver System, passed the record-breaking 1,200 bar pressure test (SVTI No. 114’937) – the equivalent to a depth of 12,000 meters! – carried out by the Swiss Association for Technical Inspections SVTI (EMPA) in 1999.
