The Orient Kamasu RA-AA0003R39B is the red-dial automatic diver in Orient’s Kamasu (Mako III) sports line — the same generation as the better-known green and blue pieces, with a crimson sunburst dial behind sapphire. “Kamasu” is Japanese for barracuda: triangular markers and arrow hands read like teeth, and the 120-click bezel uses a dotted-minute track between the bold numerals rather than a plain dive scale.
This is a daily steel sports watch first. 41.8 mm across, about 12.8 mm thick, 22 mm lugs, screw-down crown, and a genuine 200 m rating. If you already like Orient divers and want a red dial that still wears like a tool watch, this is the reference to look at — not a fashion piece with a dive bezel glued on.
Why the RA-AA0003R39B works
- Red Kamasu dial: High-contrast markers and lume on a colour that stands apart from black/blue dive watches without looking novelty.
- Sapphire crystal: Flat sapphire on the front — the same step up from mineral that made this generation popular.
- Orient F6922 automatic: Self-winding with hand-winding and hacking seconds; about 40 hours reserve; day and date.
- 200 m water resistance: Screw-down crown, screw case back, unidirectional 120-click steel bezel.
- Steel bracelet: Solid-link bracelet with hollow end links, 22 mm lug width, fold-over clasp with safety.
- Same case as the rest of the family: 41.8 mm, ~12.8 mm thick, ~46.8–47 mm lug-to-lug — typical Kamasu/Mako III proportions.
Design and dial
The dial is red with luminous hands and hour markers. Day and date sit at 3 o’clock, in line with other F6922 Kamasu models. The bezel is stainless steel with a 120-click unidirectional action; the minute track uses Orient’s dotted pattern between the numerals, which is part of why the Kamasu looks different from a generic hommage diver.
Regional catalogue codes for the same red Kamasu include RA-AA0003R19A and RA-AA0003R19B. Chronospride lists the watch as RA-AA0003R39B — that is the store SKU and the code Orient Watch USA prints on the product. Same red dial, same F6922, same 41.8 mm steel case.
Movement: Orient calibre F6922
F6922 is Orient’s in-house automatic for this sports generation: rotor winding, manual winding, hacking seconds, day-date, roughly 40 hours of power reserve. Wear it and the rotor keeps it running; if it has sat still, wind it on the crown and set the seconds precisely with hacking. It is the same calibre used across Kamasu / Mako III steel divers, not a quartz module and not a dress-watch F67xx.
