Founded in La Chaux-de-Fonds in 1895, Rotary carries a storied heritage of British and Swiss watchmaking. The Seamatic collection has gained a cult following for offering high-tier specifications without the inflated Swiss luxury markup. The Seamatic GMT elevates this ethos for globetrotters.

Tracking Dual Time Zones with Precision

The standout feature is the arrow-tipped GMT hand that completes one full revolution every 24 hours. Paired with the bidirectional 24-hour bezel, tracking home time and local time when landing across time zones is effortless and intuitive.

Dial Finishing and Cyclops Magnifier

Under the anti-reflective sapphire crystal, the matte dial features applied hour markers with polished chamfers that catch ambient light beautifully. A date window at 3 o'clock is enhanced with a magnifying Cyclops lens, offering instant legibility at a glance.

Solid-Link Stainless Steel Bracelet

Unlike budget alternatives that employ hollow folded metal links, the Seamatic GMT is outfitted with a reassuringly hefty solid stainless steel bracelet featuring brushed outer links and mirror-polished center accents, terminating in a secure deployant clasp.
