The M20 GMT Diver is up to virtually any task, with its double-dome AR sapphire crystal, applied indices containing SuperLuminova luminous and 200M depth rating. The case has a diameter just under 42mm but feels smaller on the wrist than one might expect, due to its rounded shape. The M20 GMT Diver boasts both serious diving capabilities and the ability to track multiple time zones at once.
