Is the Kamasu a true dive watch?

Yes. It has 200 m water resistance, a screw-down crown and a unidirectional rotating bezel, so it meets the core dive-watch requirements.

Does it have a sapphire crystal?

Yes. The Kamasu uses a scratch-resistant sapphire crystal, which is a step above the mineral glass on many rivals.

How does it compare with the Orient Ray II?

The Kamasu adds sapphire crystal and a slightly different case shape. The Ray II uses mineral glass but is otherwise similar in movement and water resistance.

What movement does it use?

It uses an Orient in-house automatic movement with hacking and hand-winding, visible only through the caseback on some versions.

Will the 42 mm case fit a small wrist?

It can, but the 13 mm thickness makes it sit high. Try it on if you have a wrist under about 6.5 inches.

Is the bracelet easy to change?

It has standard 22 mm lugs, so most 22 mm straps and bracelets fit with a spring bar tool.

Our take on the Orient Kamasu Automatic Green Dial Men's Watch RA-AA0004E19B

The Orient Kamasu is a dive-style automatic watch with a 42 mm stainless steel case, a green dial with luminous hands and markers, and a unidirectional rotating bezel. It stands out for its in-house automatic movement, sapphire crystal and 200 m water resistance, features usually found on pricier divers. It suits buyers who want a real mechanical diver without paying luxury prices. Against rivals like the Seiko 5 Sports or the Orient Ray II, it adds sapphire and a screw-down crown, though its bracelet and clasp are plainer than those on more expensive divers.
