With a bi-directional 24-hour GMT bezel, the Spirit Zulu (in both sizing) mirrors the operate set established by fashionable GMTs just like the Tudor Black Bay GMT, the Black Bay Professional, and the Rolex GMT-Grasp II. Principally, you may set the primary time show to point out native and the 24-hour hand to point out house time (leaving the bezel in its pure place), or you may modify the 24-hour hand to point out UTC time after which rotate the bezel to point out a 3rd time zone (native, UTC, and UTC offset). To place a bow on the specs, the crystal is sapphire, the caseback is closed, the lugs usually are not drilled, the crown screws down, the bezel insert is ceramic (non-lumed, except for the triangle marker), and the water resistance is 100 meters.
