The Editorial

Orient's in-house automatic in a 200m diver with sapphire crystal — at a price that makes the competition look absurd. The Kamasu is why budget dive watch discussions always end with 'just get the Orient.'

Why This Watch

A piece worth
acquiring.

Ideal for

The budget diver who refuses to compromise. The modder looking for a solid base. The first-time mechanical watch buyer who wants to go swimming.

The Kamasu is the dive watch that ended every 'best budget diver' debate. Orient's in-house automatic, sapphire crystal, 200m water resistance, and solid end-links on the bracelet — at $345. Every other brand at this price uses a mineral crystal and a Miyota movement. Orient uses their own.

Collector's Note

The Kamasu's bracelet quality punches well above its price. The solid end-links and screw-pin links are features usually found at $500+.
