The black Orient Kamasu RA-AA0001B is the plain steel-bracelet Mako III. If you have been comparing an Orient Kamasu and a Mako 3, this is the black reference those names usually point at: applied markers, a red-tipped seconds hand, and a day-date window at 3.
Kamasu means barracuda. Collectors use it for this generation of the Mako, the one with a sapphire crystal and calibre F6922. The store SKU is RA-AA0001B. Some export sheets also write RA-AA0001B19B for the same black watch. It is not the blue rubber RA-AA0006L, and Orient does not list it as a numbered limited edition.
What this reference is
Orient’s sheet for RA-AA0001B lists a mechanical calibre F6922 with automatic winding and hand-winding, 22 jewels, a sapphire front crystal, a stainless steel case and metal bracelet, a rotating bezel, a screw case back, day and date, and 200 metres of water resistance. Case width is 41.8 mm. Lug-to-lug, listed as case height on that sheet, is 46.8 mm. Thickness is blank on the Orient page. Other sheets for this same reference, and the rest of this Kamasu case, publish 12.8 mm. Lug width is 22 mm.
Older text on this page called it a Seiko diver, gave it a mineral crystal, a 42 mm case, 21 jewels, and Arabic numerals. None of that matches the Orient sheet or the listing photos. The dial uses a triangle at 12 and bar markers on the other hours, not Arabic numerals.
Dial, bezel, and bracelet
The dial is black. The hour and minute hands are silver-toned, with luminous fill. The seconds hand has a red tip. The day-date window at 3 is the only calendar. The dial prints Water Resist 20 bar, which is the same 200 metre rating. A small movement line near 6 on the listing photos is an older stamp. Do not read that line as a description of the unit we would send. The note at the bottom of this page covers it.
The bezel insert is black, with a luminous pip at 12 and white minute numerals. It turns one way. The crown sits at 3, with guards, and screws down. The case back is solid, with the Mako emblem. One gallery frame shows an Epson mark on that back. The surrounding engraving is not clear enough to quote. The bracelet is stainless steel, closed with a fold-over clasp, a push button, and the Orient logo on the clasp.
Day to day
At 41.8 mm wide and 46.8 mm lug to lug, this sits at the compact end of a modern diver. It is a steel everyday watch that can also go in the water, not a dress watch. Two hundred metres covers swimming and ordinary water use. This page does not call it an ISO-certified diver. Orient’s sheet for this reference does not use that label.
It is out of stock here at the moment. The price on the page is A$430. When a unit is in, it is checked before it leaves, and eligible orders ship free Australia-wide.

Questions buyers ask
Is the Orient RA-AA0001B a Kamasu or a Mako III?
Both. Kamasu is the nickname for this Mako generation. The black RA-AA0001B is the steel-bracelet version with applied markers. It is not the blue rubber Mako III, and it is not a Mako II.
What movement does the RA-AA0001B use?
Orient calibre F6922. It winds from the wrist and can also be hand-wound. It has 22 jewels, a power reserve of about 40 hours, and a hacking seconds hand so you can set the time against a clock. This page does not claim the movement is made in one country.
What is the water resistance of the Orient Kamasu RA-AA0001B?
200 metres. The dial prints 20 bar, and the crown screws down. Rinse it after salt water. That rating is for swimming and recreational water use, not a claim of ISO dive certification.
How big is the RA-AA0001B?
Orient lists 41.8 mm across and 46.8 mm from lug to lug. The lugs are 22 mm, so a 22 mm strap fits if you take the bracelet off. Thickness is about 12.8 mm on sheets for this reference. Orient’s own page leaves thickness blank, so this listing does not invent a second figure.
Is the crystal sapphire or mineral?
Sapphire. Mineral crystal belongs to the older Mako II, not this Kamasu. If you still see mineral in an old snippet, that copy has been replaced.
Is the black Kamasu RA-AA0001B a limited edition?
No. Orient’s sheet for this reference does not give a piece count. Limited colourways in the wider Kamasu family are different SKUs.
