M20 GMT 42mm

M20 GMT — Built for Adventure Across Time Zones

The M20 GMT returns with thoughtful upgrades that make this versatile sports watch even more efficient and convenient to own.

The M20 GMT moves effortlessly between casual, active and more dressed-up settings. Its full dive-ready construction, including a screw-down crown and 200M water resistance makes it tough enough for demanding adventures, while its clean, elegant design looks equally at home at dinner or in the office.

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.

The dedicated GMT hand allows you to track a second time zone at a glance - ideal for frequent travellers, international calls or simply keeping track of time somewhere important to you.

A double-dome sapphire crystal provides exceptional scratch resistance while adding a distinctive vintage-inspired bubble effect that complements the softly rounded case. Super-LumiNova® on the hands and dial markers ensures excellent visibility when the light fades.
