Black Mako III diver, on a steel bracelet
The Orient Kamasu RA-AA0008B19B is the black dial in the first Mako III case, the watch many shops also file as a Kamasu. It is a straightforward automatic diver: black dial, black bezel insert, steel case and steel bracelet, with the day and the date in a window at 3. It is not the Kanno, and it is not a numbered limited edition.
The front view in this listing shows rectangular hour markers, a triangle at 12, silver-tone hands, and the words Water Resist 20 bar under the hands. Angled photos in the same set show a small red tip on the seconds hand. One side-profile frame shows a blue bezel insert. That frame does not match the black insert on the dial photos, so it should not be read as the bezel on this reference.
People shop this reference when they want the plain black Kamasu rather than a colour-matched bezel or a leather-strap limited edition. The bracelet is the everyday version of the case. The rotating bezel is a minute scale, not a GMT scale.

Ignore a catalogue row that prints this code as 44 mm by 50 mm, and ignore a shop sheet that calls it a Kanno with mineral glass. Neither matches the watch in these photos. The Kanno is a different reference, RA-AA0912. The matching black Mako III sheet, RA-AA0001B, lists 41.8 mm, 46.8 mm, a sapphire crystal and 22 jewels. The case back in this gallery is engraved sapphire crystal.
How it wears
At 41.8 mm across and 46.8 mm lug-to-lug, this is the compact Kamasu case, not a 44 mm diver and not the larger Mako XL. The steel bracelet and the black dial make it the plain version of the family. It is built for swimming and everyday wear at the stated 200 metres. It is not sold here as a professional saturation diver, and the dial rating should be retested if the watch is used in the water often.
Two gallery files are named RA-AA0001B. They show the same black dial layout, including the red-tipped seconds hand. They are sibling catalogue frames, not a second colourway.
Questions buyers ask
Is the RA-AA0008B19B a Kamasu or a Kanno?
It is a Mako III / Kamasu. The Kanno is a different reference, RA-AA0912. Some third-party titles have swapped the names on this code. The dial layout in this listing is the Kamasu layout: triangle at 12, bars for the hours, day and date at 3, black insert.
What movement does the Orient RA-AA0008B19B use?
Calibre F6922. It is an automatic movement that can also be hand-wound, with a hacking seconds hand and 22 jewels. Orient rates this calibre at about +25 to −15 seconds a day, with about 40 hours of power reserve.
What is the water resistance of the RA-AA0008B19B?
The dial is marked Water Resist 20 bar, which is 200 metres. The case back in the gallery repeats a 20 bar line. That is the figure to use. It is enough for swimming. It is not a claim that the watch is an ISO-certified saturation diver.
What size is the RA-AA0008B19B?
41.8 mm across and 46.8 mm lug-to-lug, from Orient’s sheet for the matching black reference RA-AA0001B. Thickness is not printed on that sheet. The same case is about 12.8 mm thick on matching sheets. Figures of 43 mm, 44 mm or 50 mm do not describe this watch.
Does the RA-AA0008B19B have a date?
Yes. Day and date sit together at 3 o’clock. The bezel is a minute timer, not a second time zone.
Is the crystal mineral or sapphire?
Sapphire. The case back photographed for this listing is engraved sapphire crystal, and Orient’s sheet for the matching Mako III reference lists a sapphire crystal. A mineral-glass label on an old import does not match that engraving.
Is the RA-AA0008B19B made in Japan?
Orient is a Japanese brand. Dial photos and the case back in this gallery can show an older movement stamp. That stamp is not the origin line for current production of this reference, which is still in Orient’s diver catalogue and is marked Made in Thailand. The calibre name is F6922. The movement’s country is not stated here.
