The Orient Kamasu RA-AA0002L19B (also sold as Mako III) is the blue-dial steel-bracelet version of Orient’s modern 200 m sports diver. It is built around the in-house F6922 automatic, a sapphire crystal, a 120-click unidirectional bezel, and a screw-down crown — the combination most Australian buyers actually want when they search for an affordable Orient dive watch they can wear to work and into the water.
Kamasu is Japanese for barracuda. On this reference the idea shows up as pointed indices and sword hands on a blue sunburst dial, with a matching blue bezel insert and lume on the hands and markers. It is a tool-leaning watch, not a dress piece: solid case back, day-date at 3 o’clock, and a 22 mm steel bracelet.
Why the RA-AA0002L19B works as a daily diver
At about 41.8 mm across and 12.8 mm thick, the Mako III case is easier on smaller wrists than a 44–45 mm “full size” diver, while still reading clearly at a glance. Lug-to-lug is around 46.8 mm on this generation, so it sits flatter than the diameter alone suggests. The F6922 adds hand-winding and hacking (seconds stop), which older Orient dive calibres often skipped — useful when you actually set the time against a reference.
Sapphire is the other reason this generation replaced the older mineral-crystal Makos. It will not shrug off every knock, but it resists desk-diving scratches far better than mineral, which is the usual complaint on vintage-style Orient divers. 200 m water resistance with a screw-down crown is the rating Orient publishes for this line; treat it as a swim and snorkel watch, not a saturation tool.

Frequently asked questions
What is the water resistance of the Orient Kamasu RA-AA0002L19B?
200 metres (20 bar), with a screw-down crown. That is appropriate for swimming, snorkelling, and shower wear if the crown is fully screwed down. It is not a professional saturation dive instrument. Rinse after salt water and have the seals checked on a normal service interval.
Is the RA-AA0002L19B a Kamasu or a Mako III?
Both names are used for this generation. Orient’s sports line is often labelled Mako III in some markets and Kamasu in others. RA-AA0002L19B is the blue-dial steel-bracelet reference on the F6922, sapphire, 200 m platform — the same family as later RA-AA081* Kamasu SKUs.
What movement does the Orient RA-AA0002L19B use?
Orient F6922: automatic, 22 jewels, 21,600 beats per hour, roughly 40 hours of reserve, with hand-winding and hacking. It is Orient’s own calibre, not a third-party quartz module.
What is the case size of the RA-AA0002L19B?
About 41.8 mm across (excluding crown), about 12.8 mm thick, 22 mm lugs, lug-to-lug around 46.8 mm. That is the modern Mako III / Kamasu case, not the older 40 mm Mako or the larger “Mako II” proportions.
Does this watch have a sapphire crystal?
Yes. The RA-AA0002L19B uses sapphire, which is the main upgrade versus older mineral-crystal Orient divers. The case back is solid steel, not exhibition.
Is the Orient Kamasu RA-AA0002L19B suitable as an everyday watch?
Yes, if you want a sports watch rather than a thin dress piece. The steel bracelet, 200 m rating, and lume make it a one-watch option for commuting, weekends, and swimming. It will wear larger than a 38 mm Bambino; try the 41.8 mm figure against your wrist before assuming it is “small”.

Buying notes
The store SKU is RA-AA0002L19B (steel bracelet). Some catalogues also list an L39B suffix when an extra rubber strap is bundled; do not assume this listing includes a second strap unless the product photos and packing list show one. Title leftovers that mention RA-AA0002L39B refer to that strap-code variant, not a different dial.
