HYPERTEC^® & SDW^® - SWISS WATCHES WITH DEPTH

ATHLETIC HYPERBAR^® DEEP DIVER MODELS AND CLASSIC WRIST WATCHES

Welcome to the Chronotime AG homepage!

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 - the equivalent to a depth of 12,000 meters! - carried out by the Swiss Association for Technical Inspections SATI (EMPA) in 1999. This greatly outperformed our previous test at 900 bar, conducted in 1996.

Launched in 2002, the Hypertec^® brand includes various high-quality classic ladies' and men's wrist watches, as well as a dedicated line of watches equipped with the Hyperbar^® Deep Diver System.

But don’t just take our word for it - take a look for yourself!
