The Orient Mako GMT RA-BC0003L is the blue sunburst version of Orient’s first Mako with a dedicated GMT hand. Same 42.8 mm sports case as the rest of the RA-BC000* family, same F6P22 automatic, same 24-hour bezel — quieter colour than the orange RA-BC0004Y, still a proper second-zone tool for a weekday wrist., sapphire, 200 m, steel bracelet.
RA-BC0003L / RA-BC0003L30B is the blue sunburst Mako GMT. Green in the same launch set is a different reference. This page URL still contains the word “green” from an earlier listing; the watch itself is blue.
Why the blue RA-BC0003L is the sensible Mako GMT
- Blue that still reads as a tool watch. Sunburst blue, luminous hands and markers, date at 3, GMT legend above 6. It looks like a Mako, not a dress GMT.
- Second time zone the simple way. Extra 24-hour hand plus a unidirectional 24-hour bezel. Not a flyer GMT: you do not jump the local hour on its own.
- Same case as the orange sibling. 42.8 mm, 49.5 mm lug-to-lug, 13.4 mm thick, 22 mm lugs — a step up from the 41.8 mm non-GMT Mako / Kamasu.
- Sapphire, screw-down crown, 200 m. Built for swimming and daily knocks. Orient does not present this as an ISO 6425 professional diver, and neither do we.
- Steel bracelet, solid end links. Push-button deployant clasp; 22 mm at the lugs if you later swap to rubber.
How the Mako GMT complication works
Calibre F6P22 adds a central 24-hour hand geared to the hour hand. Rotate the 24-hour bezel to line that hand up with home or destination time. Minute and seconds hands stay with local time. Date is at 3; there is no day-of-week window. WatchNation and Helveti both describe this first-generation layout — extra hand and bezel, not an independent-hour traveller GMT.

Who it is for
Choose RA-BC0003L if you want the new Mako GMT in blue rather than orange, and you are fine with a 42.8 mm steel sports watch. Choose the RA-BC0004Y orange GMT if you want more colour. More Orient sports watches live under Orient divers.
Frequently asked questions
What movement does the Orient Mako GMT RA-BC0003L use?
Orient F6P22 automatic with hand-winding and hacking seconds, about 40 hours of reserve, date, and a 24-hour GMT hand. Quoted accuracy is +25 to −15 seconds per day.
Is the RA-BC0003L dial green or blue?
Blue sunburst. Older listing text on this page said green; the RA-BC0003L reference is the blue Mako GMT. Green in the launch set is a different SKU.
Can I set local time independently like a flyer GMT?
No. The GMT hand is linked to the hour hand. The 24-hour rotating bezel is how you read a second zone.
What are the case dimensions?
42.8 mm diameter, 49.5 mm lug-to-lug, 13.4 mm thickness, 22 mm lug width. Larger than the 41.8 mm Mako III / Kamasu case.
Is the RA-BC0003L sapphire and 200 m water resistant?
Yes: sapphire crystal, 200 m rating, screw-down crown and screw case back. Suitable for swimming; not sold as an ISO professional dive watch.
