The Depthmaster is based on the 1964 classic from Nivada Grenchen called the "Depthomatic". The Depthomatic was one of the first true dive watches, as it was the first on the market that featured a depth gauge. One year later the Depthmaster came into productions as we know it today. The Depthmaster features a comfortable 38mm cushion style case, unique art deco numerals, a date window and an astronomical 1000m water resistance.
