Sealed under pressure, they are also resistant to water, oil and most corrosive materials. Combined with superb Swiss-manufactured watch craftsmanship, their robust merits have made Traser watches an absolute must in the emergency, safety and protection sectors as well as in the armed forces - while also ideal for fans of outdoor adventure and sport.

Traser is still the leading brand of self-luminous watch favoured by UK Special Forces and US Navy Seal divers. Each watch is built entirely in Switzerland by MB-Microtec, not (as with most other competing brands) in China or the USA. "Traser" and "Traser H3" are brand names for self-illuminated products by MB-Microtech, who are world leaders in the tritium (hydrogen³ or H3) technology needed to make permanent (25 year) light sources. In the 1970s they were the first ever to install them in watch faces and in 1990 they went on to become the first ever company to build robust military watches meeting US Pentagon specifications defined in MIL-W-46374 F.
