Orient Mako 40 RA-AC0Q10N30B
The RA-AC0Q10N30B is Orient’s Mako 40, also catalogued as the AC0Q-40 diver. It is the smaller sibling of the 41.8mm Mako III, built for a wrist that finds the usual dive watch a bit tall. The case is 39.9mm across, 46.5mm lug to lug and 12.8mm thick, with a charcoal grey dial, a dark grey-plated bezel and a black silicone strap.
It is a daily watch that can go in the water, not a desk diver with a printed bezel. Screw-down crown, solid screw case back, sapphire crystal and 200m water resistance. The store reference is RA-AC0Q10N30B. Orient also lists the shorter code RA-AC0Q10N for the same watch.
Who it suits
Buy this if you want Orient diver looks under 40mm, and you would rather have silicone than a steel bracelet. The charcoal dial and dark case sit quieter than a black-and-blue Mako, and the gold-tone seconds hand is the only bright accent. Applied bar markers, a date at 3, and a unidirectional bezel with 10-minute numerals.
It is not the Kamasu or Mako III. Those use the F6922 in a 41.8mm case, usually on a steel bracelet. This one uses the F6722 in the 39.9mm AC0Q case. If you already wear a 42mm diver and want the same presence, look at the larger Mako. If you want the diver shape without the bulk, this is the one.
Movement and water resistance
Calibre F6722 is an in-house Orient automatic with hand-winding and a hacking seconds hand, so you can stop the seconds and set the time against a clock. Power reserve is about 40 hours. The listed jewel count is 22. The rated accuracy on this listing is +25 to −15 seconds a day, which is the usual Orient window for this family, not a chronometer claim.
The case back in the listing photos is a solid screw back, engraved water resistant 200m, stainless steel, sapphire crystal, and calibre code F6722-UAY0. It is also marked Made in Thailand. That engraving is a catalogue photo, not a promise about a particular serial.
Water resistance is 20 bar / 200m, with a screw-down crown and a 120-click unidirectional bezel. Fine for swimming and surface water use when the crown is screwed down. Rinse it after the pool or the sea. This page does not call it a professional saturation diver.

Common questions
What movement does the Orient Mako 40 RA-AC0Q10N30B use?
Orient calibre F6722. It is an automatic with hand-winding and hacking, about 40 hours of power reserve, and 22 jewels. The case back in the listing photos is engraved F6722-UAY0. It is not the F6922 used in the 41.8mm Kamasu and Mako III.
What size is the RA-AC0Q10N30B?
39.9mm across, 46.5mm lug to lug, 12.8mm thick, 20mm between the lugs. That is the official AC0Q-40 size. Some retailer sheets round the diameter to 40mm or list a thicker case. This page uses Orient’s 39.9mm and 12.8mm figures.
What colour is the dial?
Charcoal grey, not black. The listing photos show a grey dial, silver hour and minute hands, a gold-tone seconds hand, and a date window at 3. The case and bezel are grey-plated stainless steel and read dark in those photos. The strap is black silicone.
Is the RA-AC0Q10N30B water resistant to 200m?
Yes. Orient rates it to 200m / 20 bar, with a screw-down crown and a unidirectional bezel. The dial is printed Water Resistant 20 bar, and the case back is engraved 200m. Screw the crown down before it goes in the water.
Is RA-AC0Q10N the same watch as RA-AC0Q10N30B?
Yes. RA-AC0Q10N30B is the store SKU and the full reference. RA-AC0Q10N is the shorter catalogue code Orient uses for the same grey Mako 40. Do not mix it with another AC0Q colour, such as the black RA-AC0Q01B30B.
How does this compare with the Mako III?
The Mako III and Kamasu are about 41.8mm, with the F6922 and, on most references, a steel bracelet. The Mako 40 is 39.9mm, uses the F6722, and this colour comes on black silicone. Same diver idea, smaller case, different movement.
