Orient Mako GMT 43mm Orange Dial Steel Mens Automatic Watch RA-BC0004Y30B

The Orient Mako GMT RA-BC0004Y30B is part of Orient’s Autumn/Winter 2026 collection, featuring a vivid orange dial framed by a black and grey 24-hour bezel. The 42.8mm stainless steel case measures 49.5mm from lug to lug and 13.4mm thick, giving the watch a substantial profile. The dial combines luminous applied hour markers with a framed date display at 3 o’clock, while the contrasting GMT hand provides an additional time-zone indication. A stainless steel 3-link bracelet with solid end links completes the watch.

Orient F6P22 Automatic GMT Movement

The watch is powered by Orient’s F6P22 automatic movement, which offers approximately 40 hours of power reserve and an accuracy of +25 to -15 seconds per day. It operates the hours, minutes and seconds hands alongside the GMT hand, allowing a second time zone to be followed using the 24-hour bezel.

24-Hour Rotating Bezel

The outer bezel features a 24-hour scale with 120 notches and rotates to assist with reading another time zone. The black and grey bezel provides contrast against the orange dial, while the GMT hand adds a clear reference for the second time-zone display. As with the first-generation GMT configuration, the GMT hand cannot be adjusted independently.

Orange Dial, Luminous Details & 200m Water Resistance

The orange dial gives this Mako GMT a stronger colour contrast, with luminous material applied to the hands and hour markers for visibility in low-light conditions. A framed date window sits at 3 o’clock, adding a useful calendar function to the layout. The 20 bar (200m) water resistance complements the watch’s robust Mako styling, while the stainless steel 3-link bracelet and solid end links provide a secure finish.
