Orient Mako GMT 43mm Black Dial Steel Mens Automatic Watch RA-BC0001B30B

The Orient Mako GMT RA-BC0001B30B is part of Orient’s Autumn/Winter 2026 collection, combining the familiar Mako dive-watch design with a GMT function for tracking a second time zone. This version features a black dial with a matching black and grey 24-hour bezel, luminous hour markers and a framed date display at 3 o’clock. The 42.8mm stainless steel case measures 49.5mm from lug to lug and 13.4mm thick, giving the watch a substantial presence on the wrist. It is completed with a stainless steel bracelet featuring solid end pieces.

Orient F6P22 Automatic GMT Movement

The watch is powered by Orient’s F6P22 automatic movement, with approximately 40 hours of power reserve and a stated accuracy of +25 to -15 seconds per day. The GMT hand allows a second time zone to be read against the 24-hour bezel. This first-generation GMT setup uses the rotating bezel to indicate the additional time zone rather than allowing the GMT hand to be adjusted independently.

24-Hour Unidirectional GMT Bezel

A two-tone rotating bezel surrounds the dial, marked with a 24-hour scale for the GMT function. Its 120-notch unidirectional mechanism allows the bezel to be positioned to track a second time zone. The black and grey colour combination follows the dial and dial ring for a coordinated appearance.

Black Dial, Luminous Markers & Stainless Steel Bracelet

The black dial uses luminous hour markers and hands for improved visibility, with the red GMT hand providing a clear indication of the additional time-zone reading. A framed date window sits at 3 o’clock, while the 20 bar water resistance and Mako-inspired case design support use across a range of everyday environments. The stainless steel bracelet has solid end pieces, completing the watch with a substantial metal finish.
