The Orient Kamasu RA-AA0004E19B is the green-dial, green-bezel steel-bracelet diver on Orient’s F6922 platform. Same recipe as the rest of the modern Kamasu / Mako III line: sapphire crystal, 200 m water resistance, screw-down crown, 120-click unidirectional bezel, and a Japan-made automatic that you can hand-wind and hack.
Green is the colour that made this reference easy to spot in a line-up of blue and black Kamasus. The dial is a sunburst green with luminous sword hands and applied indices; the aluminium bezel insert is green to match. “Kamasu” (barracuda) is Orient’s name for the pointed marker set — more sports watch than dress watch, which is the point.
Why this green Kamasu is still a sensible buy
You get a true 200 m sports case without jumping to a 44 mm Sumo-style watch. Diameter is 41.8 mm without the crown, thickness about 12.8 mm, lug-to-lug about 46.8 mm, 22 mm lugs. That generation sits in the “will work on most adult wrists” band, which is why Kamasu remains one of the searches Australian buyers actually use.
F6922 is the movement to insist on if you are comparing older Makos: 22 jewels, 21,600 vph, about 40 hours of reserve, hand-winding and hacking. Sapphire replaces the mineral crystal on earlier Orient divers, so daily desk wear is less likely to haze the glass. The case back is solid — this is not a show-the-rotor piece.
Browse the wider Orient watches catalogue, the Kamasu buyer notes, the blue RA-AA0002L19B Mako III, or the grey RA-AA0810N19B if you want a quieter dial on the same architecture.
Who it suits
- Someone specifically after a green Orient dive watch with sapphire and a steel bracelet.
- Buyers stepping up from mineral-crystal Makos who still want a sub-42 mm case.
- Daily wear that can go swimming without swapping to a beater quartz.

Frequently asked questions
What is the water resistance of the Orient Kamasu RA-AA0004E19B?
200 metres. Screw the crown down before water. Suitable for swimming and snorkelling; rinse after salt water. Not a professional saturation diver.
What movement is inside the RA-AA0004E19B?
Orient F6922 automatic: 22 jewels, 21,600 vph, roughly 40-hour reserve, hand-winding and hacking seconds. Same calibre as the blue RA-AA0002L19B and later RA-AA081* Kamasu models.
Does the green Kamasu use sapphire?
Yes. RA-AA0004E19B is sapphire-crystal, steel-bracelet, 200 m. Do not mix it up with older mineral-crystal Orient divers or leather-strap dress pieces that share the Orient name only.
What size is the RA-AA0004E19B on the wrist?
41.8 mm diameter, about 12.8 mm thick, 22 mm lug width, lug-to-lug about 46.8 mm. It is the modern Mako III case, not the compact 40 mm Mako (RA-AC0Q*) and not a 45 mm Turtle.
Is the Orient Kamasu RA-AA0004E19B good for everyday wear?
Yes, if you like a coloured bezel. The green insert is more visible than a black or grey Kamasu, which is either the appeal or the reason to pick another SKU. The bracelet and 200 m rating make it a one-watch sports option.
Kamasu vs Mako III — which name is correct?
Marketing names overlap. This reference is the green Kamasu on the Mako III / F6922 generation. Search either “Orient Kamasu green” or “Orient Mako 3 green”; the code that matters is RA-AA0004E19B.
