Land // Sea GMT — 38mm Miyota 9075 True GMT Watch Your Time. Anywhere. The Land // Sea GMT is Seals Watch Company's dual-time tool watch, built on the same 38mm 316L stainless steel platform as the Land // Sea Classic, extended with a true traveler GMT complication and a recessed 24-hour internal chapter ring. Designed for daily wear across time zones, assembled and regulated in Sacramento, California. The Miyota 9075 movement at its core is a true traveler GMT: the local hour hand adjusts independently in one-hour increments without stopping the movement or disturbing the GMT hand. Set your home time once. Cross time zones with a single crown pull. That's it. What Is a True GMT and Why Does It Matter? GMT movements fall into two categories. A caller GMT adjusts the 24-hour hand, useful for tracking a distant time zone from one location, but cumbersome when you're actually crossing time zones. A true traveler GMT adjusts the local hour hand independently, meaning you can flip between zones without resetting minutes, seconds, or your home reference time. The Miyota 9075 is a true traveler. The Land // Sea GMT is built around this distinction. Read the full movement breakdown in our Miyota 9075 guide . Fixed Bezel. Internal 24-Hour Chapter Ring. Rather than a rotating external bezel, the Land // Sea GMT uses a fixed radially brushed bezel paired with a recessed internal 24-hour chapter ring. The bezel profile stays clean and uninterrupted. The ring, available in Burnt Sun, Olive Drab, black with summer teel or Everest Blue, provides the day/night reference from within the dial. Less external mass. More dial depth. The same time zone functionality, expressed differently. Why we chose this approach. Key Features True Traveler GMT: Miyota 9075 with independent local hour hand adjustment. Change time zones without stopping the movement. Internal 24-Hour Chapter Ring: Fixed bezel design with recessed dial ring in four colorways, Burnt Sun, Olive Drab, Everest Blue, and Summer Teal. 38mm Case: 316L stainless steel, 46mm lug-to-lug, 12.5mm thick. Wears appropriately on 6 to 8 inch wrists. Domed Sapphire Crystal: Anti-reflective coated, consistent with the Land // Sea Classic platform. 150 Meters Water Resistance: Screw-down crown, suitable for swimming and surface water use. Regulated In-House: Each movement adjusted to ±5 sec/day at time of assembly in California. Applied Indices + Super-LumiNova: Swiss lume on hands and indices for low-light legibility. 20mm Lug Width: Compatible with the full Seals strap lineup and most standard 20mm aftermarket straps.
