Orient Kamasu RA-AA0819N19B Grey Automatic Diver Watch (Mako III)

The Orient Kamasu RA-AA0819N19B is a Japan-made automatic diver with a grey dial, sapphire crystal and 200m water resistance. Sold in Australia as part of the same family many buyers also call Mako III, it pairs an in-house F6922 movement with a steel bracelet and a unidirectional dive bezel for everyday wear and real swimming use.

If you want an affordable Orient dive watch that still feels solid on the wrist, this grey Kamasu is a practical choice: clear dial contrast, day-date at 3 o’clock, hand-winding and hacking, and a finish that works with jeans or smarter casual clothes without looking costume-like.

Why the grey Kamasu works

• Grey dial readability — muted tone that still pops under the luminous markers and hands in low light.
• Sapphire crystal — harder than mineral glass and more resistant to daily scratches.
• 200m water resistance — suitable for swimming and showering when the crown is secured; a genuine dive-rated case design, not dress-watch splash resistance.
• In-house F6922 automatic — self-winding Japanese movement with day-date, manual wind and seconds hacking.
• Steel bracelet — integrated sports look with solid end-links feel on a ~42mm class diver.

On the naming side: retail listings often say Orient Kamasu while some markets and older catalogues use Mako III for the same generation. Content and search demand for both terms matter in Australia, so this page covers the reference RA-AA0819N19B under both names where accurate.

Frequently asked questions

What is the water resistance of the Orient Kamasu RA-AA0819N19B?

200 metres. That is dive-watch rating with a screw-down style sports construction. Always set and secure the crown before water exposure. Gasket condition still matters over years of wear — treat 200m as a design rating, not a permanent seal guarantee.

Is the Orient Kamasu the same as the Orient Mako III?

For this generation, yes in practical terms: RA-AA0819N19B is sold as Kamasu and sits in the Mako III family used in many catalogues. Specs buyers care about — F6922, sapphire, 200m, ~42mm class case — match across those labels.

What movement does the grey Kamasu use?

Orient’s in-house F6922 automatic. It self-winds from wrist motion, supports hand-winding, hacks the seconds hand for precise setting, and drives day-date complications.

Is the Orient Kamasu RA-AA0819N19B suitable for everyday wear?

Yes. Thickness stays reasonable for a 200m diver, the grey dial is office-friendly, and the steel bracelet handles commute and weekend use. It is larger than a slim dress Bambino, so try the ~47mm lug-to-lug feel if you have a smaller wrist.
