The Orient Kamasu RA-AA0005B19B is the gilt rubber-strap Kamasu, also sold as the Mako III. It is a black-dial automatic diver with gold-tone hands, a gold-tone bezel edge, and a black insert. It is not a steel-bracelet Kamasu, and it is not a 40 mm watch.
Orient still lists reference RA-AA0005B in the current Diver Design range. The sheet gives calibre F6922, automatic and hand-winding, 22 jewels, a sapphire crystal, a silicone strap, a rotating bezel, a screw case back, and water resistance of 20 bar (200 metres). Case width is 41.8 mm and lug-to-lug is 46.8 mm. Thickness is blank on that sheet. Hourglass lists 12.8 mm for this reference. Some other shops round the same case to 42 mm and 13 mm. Lug width is 22 mm.
The listing photos match that description. The dial is black, with a triangle at 12, rectangular markers, and gold-tone hands. The seconds hand has a red tip. Day and date sit together at 3. The dial is printed Water Resist 20 bar. The case in those photos is a dark stainless steel finish, not a bright silver case, with a gold-tone bezel edge and a black insert. The strap is black rubber. The side view shows a screw-down crown. The gallery does not include a case back or a buckle close-up. Retailer sheets for this reference describe a pin buckle. Orient’s own buckle field on this page is mislabelled as the crown, so we do not treat that line as the clasp.
Who it suits
This is the Kamasu for someone who wants the 41.8 mm diver on rubber, with gold-tone details, rather than the steel-bracelet black Kamasu. It wears as an everyday sports watch and as a weekend diver-style piece. 200 metres covers swimming and snorkelling. We do not call it an ISO-certified dive watch; Orient’s sheet states 20 bar, and that is the figure we use.
It is not a numbered limited edition. Orient’s sheet leaves the limited-edition field blank. It is also not a dress watch, and it is not the larger 44 mm Kanno.

Frequently asked questions
What movement does the Orient Kamasu RA-AA0005B19B use?
Orient’s sheet lists calibre F6922. It is an automatic with hand-winding and a hacking seconds hand, with 22 jewels. Hourglass lists about 40 hours of power reserve and a rate of +25 / −15 seconds a day for this reference. Orient’s own page leaves the power-reserve and accuracy fields blank.
What size is the RA-AA0005B19B?
41.8 mm wide and 46.8 mm lug-to-lug, with 22 mm lugs. That is Orient’s published size for RA-AA0005B. Thickness is not on that sheet. Hourglass lists 12.8 mm for RA-AA0005B19B. Shops that say 42 mm or 13 mm are rounding the same case. It is not a 40 mm watch.
Does the RA-AA0005B19B come on a bracelet?
No. This reference is the black silicone strap version. The bracelet Kamasu models are different codes, such as RA-AA0001B and RA-AA0008B19B. The strap in the listing photos is black rubber, and the lug width is 22 mm.
What is the water resistance of the RA-AA0005B19B?
200 metres, or 20 bar. The dial in the listing photos is printed Water Resist 20 bar, and Orient’s sheet says the same. The crown is screw-down. That is enough for swimming and snorkelling. We do not add an ISO diver claim that Orient does not print for this reference.
Is the black and gold Kamasu a limited edition?
No. Orient’s RA-AA0005B sheet leaves the limited-edition field empty. The gold-tone hands and bezel edge are the regular colourway, not a numbered run. There is no catalogue serial to quote, and this gallery has no case-back photo.
Is the RA-AA0005B19B made in Japan?
Orient is a Japanese brand. This reference is still on the current diver catalogue. A dial photo can show an older movement line. Use the origin note on this page for what that means. We do not describe the movement as made in one country from that catalogue line.
