The Orient Mako GMT RA-BC0005L30B is a limited-edition sports diver with a second time zone. A blue gradient dial, 24-hour unidirectional bezel and dedicated GMT hand sit in a 42.8 mm steel case — a different generation from the 41.8 mm Mako III / Kamasu line.
The in-house F6P22 automatic adds GMT to the usual hours, minutes, seconds and date. Set local time with the hour hand; the GMT hand plus 24-hour bezel tracks home time. Sapphire crystal, screw-down crown, 200 m water resistance, steel bracelet.
