Orient Kamasu Mako III RA-AA0820R19B Red Dial Automatic Dive Watch

The Orient Kamasu RA-AA0820R19B (also sold in the Mako III / Mako-3 line) is a Japanese automatic diver with a matte red dial, sapphire crystal, and 200m water resistance. The case sits around 41.8mm with a solid steel bracelet, day-date at three, and Orient’s in-house F6922 movement.

Buyers searching for an Orient Kamasu or Orient Mako 3 in Australia often want a tool-leaning automatic that still works as a daily beater. This red dial reference keeps the expected Kamasu recipe: hacking and hand-winding, lume on hands and markers, and a unidirectional bezel for dive timing on the surface.

Why this red Kamasu works

• Distinct matte red dial that still reads clearly with lume hands and indices
• Sapphire crystal on a mid-size steel diver case (about 41.8–41.9mm)
• Orient F6922: automatic, hand-wind, hacking, roughly 40-hour power reserve
• 200m water resistance with a rotating dive bezel for real wet-use confidence beyond splash resistance
• Steel bracelet and 22mm lug width for easy strap changes after the bracelet

Frequently asked questions

Is the Orient RA-AA0820R19B a Kamasu or a Mako?

It sits in the same modern Orient dive family marketed as Kamasu and Mako III / Mako-3 depending on region and retailer. Specs match the current sapphire-crystal, F6922, 200m recipe used across that line.

What movement is inside the red Kamasu RA-AA0820R19B?

Orient F6922. It is automatic on the wrist, hand-windable, and hacking so the seconds hand stops while you set the time. Expect about 40 hours of power reserve when fully wound.

What is the water resistance of the Orient Kamasu RA-AA0820R19B?

200 metres. That is suitable for swimming and recreational diving within the stated rating when the crown is properly secured. Rinse after salt water and service seals on a normal maintenance schedule.

Does this model use sapphire or mineral crystal?

Sapphire crystal on this Kamasu / Mako III generation. That is harder than the mineral glass used on many dress Bambinos.

Is the red dial hard to read day to day?

The matte red face is bold, but applied markers and lume on the hands and hour indices keep it usable indoors and in lower light. Day and date sit at three o’clock.
