The Orient Triton RA-AC0K01B10B is a clean, Japan-made mechanical diver aimed at people who want sapphire, 200 m water resistance and an in-house automatic without jumping to premium dive-watch pricing. Matte black dial, unidirectional bezel, screw-down crown and a solid steel bracelet keep the brief simple: legible tool watch first, fashion second.
Compared with Orient’s fashion-leaning dress lines, the Triton sits firmly in the sports camp. The 43.4 mm case is assertive but not cartoonish, and at about 12.8 mm thick it wears more reasonably than many older 200 m Orient divers. If you already like Mako/Kamasu energy but want a larger sapphire-fronted sports watch with a classic black dial, this reference is worth a close look.
Why the RA-AC0K01B10B works
- Real dive rating: 200 m (20 bar) water resistance with screw-down crown, screw case back and unidirectional rotating bezel.
- Sapphire crystal: Flat sapphire on the front — a step up from mineral glass on many value divers.
- Orient F6722 automatic: Self-winding with hand-winding and hacking seconds; over 40 hours power reserve; 22 jewels.
- Clear black dial: High-contrast markers and luminous hands/markers for quick reading day or night.
- Steel bracelet: SUS316L stainless bracelet with trifold deployant clasp, push-button release and security latch; 22 mm lug width.
- Made for daily wear: Date window, magnetic resistance to JIS Type 1 (4,800 A/m or higher), Japan mechanical movement.
Design and dial
The dial is a straightforward matte black with a subtle texture in good light. Large luminous indices and sword-style hands prioritise underwater and night legibility over decoration. The date is present (no day wheel clutter), and the unidirectional bezel carries a clear dive scale with a luminous pip at 12. Crown placement and screw-down construction support the 200 m rating while keeping the case side tidy.
Do not expect a power-reserve subdial on this reference — the F6722 here is a three-hand date automatic. Older marketplace copy sometimes confuses Tritons with other Orient sports models; this page matches the official RA-AC0K01B specification.
Movement: Orient calibre F6722
Orient’s F6722 is a Japan-made mechanical automatic with manual winding and seconds hacking so you can set the time precisely. Official figures include over 40 hours of power reserve, 22 jewels, and accuracy in the region of +25 to −15 seconds per day under normal conditions. It is a practical daily calibre: wind it on the crown when the watch has sat still, or wear it and let the rotor do the work.

Who it suits
Buyers who want a black steel diver with sapphire under roughly mid-range AUD pricing, first mechanical dive watch shoppers who prefer Orient’s value-to-spec ratio, and anyone building a rotation next to a dress Bambino or a smaller Mako. The 43.4 mm size is best on medium-to-larger wrists; try the lug-to-lug figure (about 51 mm) if you are between sizes.
