M20

The M20 takes its distinctive rounded case shape from our original 1990s Aquamatic, crafted in durable 316L stainless steel for a balance of rugged capability and everyday comfort. 

Now updated with a lighter handset and higher-capacity battery for a 4–5 year battery-change interval, it also features 200M water resistance, sapphire crystal, and our signature offset screw-down crown. A Momentum classic, made even better.
