M20 DSS Diver [42mm] - Black

M20 DSS - Deep Sea System

The M20 DSS is back, with thoughtful upgrades that make this proven adventure watch even more efficient and convenient to own.

A new, lighter handset reduces the power required to drive the hands, while a higher-capacity battery extends the expected interval between battery changes from approximately 3–4 years to 4–5 years. That means less frequent servicing, less hassle and a lower long-term cost of ownership.

Built to perform in demanding conditions, the M20 DSS combines 200M water resistance with a dependable Swiss-made Ronda 515 quartz movement. Its offset screw-down crown sits comfortably away from the wrist, helping prevent “wrist bite” during active use.

The double-dome sapphire crystal adds exceptional scratch resistance and a distinctive vintage-inspired bubble effect that complements the softly rounded case. When the light fades, generously applied Super-LumiNova® on the hands and dial markers provides excellent visibility.
