The Orient Mako 40 RA-AC0Q05P10B is Orient’s smaller automatic diver-inspired watch with a distinctive salmon dial. At 39.9 mm it wears more compact than classic Mako and Kamasu models, while still offering sapphire crystal, a unidirectional steel bezel, screw-down crown, and 200 m water resistance.
Inside is Orient’s caliber F6722: automatic winding with hand-winding and hacking, about 40 hours of power reserve, and a date window. The salmon dial gives this reference more colour personality than standard black or blue divers, while the leather strap keeps the package lighter for daily wear than a full steel bracelet.
Why Choose the Mako 40 RA-AC0Q05P10B
- True compact diver proportions — 39.9 mm case, about 12.8 mm thick, 46.5 mm lug-to-lug, and 20 mm lugs for smaller wrists without losing sports-watch presence.
- Salmon dial standout — a warm, uncommon dial colour that still works with steel and leather for weekend and office-casual outfits.
- F6722 automatic — hand-wind and hack, date complication, roughly 40-hour power reserve, 22 jewels at 21,600 vph.
- Hard-wearing front glass — sapphire crystal instead of mineral on many dress models.
- 200 m water resistance — screw-down crown and unidirectional 120-click steel bezel for swimming and active use (not a substitute for professional dive certification gear).
- Leather strap comfort — ready for everyday wear; 20 mm lugs make strap swaps straightforward if you prefer a bracelet later.
Who It Suits
Choose this Mako 40 if you want a Japan-made automatic sports watch that is smaller than the 41–42 mm Kamasu/Mako line, and you like a dial that is not plain black. It fits daily commuting, travel, and swimming better than a 30 m dress Bambino, while remaining wearable under a cuff more easily than oversized tool watches.

Wearing and Care Notes
Fully screw the crown down before any water exposure. Use the unidirectional bezel by turning it anti-clockwise only for elapsed-time tracking. Hand-wind gently if the watch has stopped after sitting idle. Rinse with fresh water after saltwater use and dry the case and strap thoroughly. Leather straps prefer regular drying and are not ideal for continuous wet sports — swap to a rubber or steel strap if you swim often.
Frequently Asked Questions
What movement does the Orient Mako 40 RA-AC0Q05P10B use?
It uses Orient’s in-house caliber F6722 automatic movement with hand-winding, hacking, date, and about 40 hours of power reserve.
What is the water resistance of the RA-AC0Q05P10B?
It is rated to 200 metres with a screw-down crown and unidirectional timing bezel. That supports swimming and active water use; it is not marketed here as ISO professional dive certification equipment.
How big is the Orient Mako 40 case?
Case diameter is 39.9 mm without the crown, thickness about 12.8 mm, lug-to-lug about 46.5 mm, and lug width 20 mm.
Does the salmon Mako 40 have a sapphire crystal?
Yes. The RA-AC0Q05P10B uses sapphire crystal on the front, which is more scratch-resistant than mineral glass on many dress models.
Is the Orient Mako 40 good as an everyday watch?
Yes. The smaller case, automatic movement, and 200 m rating make it a practical daily sports watch. The salmon dial adds colour without forcing a full tool-watch look on a leather strap.
How does Mako 40 differ from Orient Kamasu?
Kamasu models are typically larger (around 41.8 mm) with the F6922 day-date movement and steel bracelet in many references. Mako 40 is closer to 40 mm, uses F6722 with date only, and this RA-AC0Q05P10B variant ships on leather with a salmon dial.
