Orient Kamasu Mako III Diver's Automatic Watch RA-AA0004E19B Green Dial 42mm

Diver's Automatic Watch for Men

The Orient Kamasu Mako III is a mechanical timepiece built for serious water sports and daily wear. Its automatic movement winds naturally through wrist motion, eliminating battery changes entirely. The 42mm stainless steel case fits a wide range of wrist sizes thanks to a resizable bracelet and an included rubber strap with a sizing tool. This watch suits divers and enthusiasts who want ISO-level capability without a luxury price tag.

200 Metres Water Resistance and Sapphire Crystal

Rated to 200 metres or 660 feet, the watch handles recreational diving, swimming and heavy water exposure with confidence. A unidirectional rotating bezel tracks elapsed time underwater, while the screw-down crown secures the case against pressure. Scratch-resistant sapphire crystal protects the green dial from impacts and abrasion. The movement provides standard day and date complications but lacks a power-reserve indicator or hacking seconds function.

Stainless Steel Build with Dual Strap Options

The silver-tone stainless steel case and bracelet feature a deployment clasp for secure, one-handed fastening. An extra diver-style rubber strap and adjustment tool ship in the original box, letting owners switch between metal and rubber for wet or dry conditions. Luminous hands and index markers ensure legibility in low light. The solid steel screw-back case adds durability, though the bracelet links require a tool for resizing.
