Orient Mako 'Kamasu' 42mm Orange Dial Steel Mens Automatic Watch RA-AA0826Y39B

The Orient Mako Kamasu RA-AA0826Y39B is part of Orient’s Autumn/Winter 2026 collection, introducing an orange dial to the returning Kamasu design. The 41.8mm stainless steel case is paired with a black unidirectional bezel, creating a strong contrast with the orange dial. The watch features the Kamasu’s familiar handset, luminous hour markers and a day-date display at 3 o’clock. Measuring 41.8mm in diameter, 46.8mm from lug to lug and 12.8mm thick, the case is fitted with a screw-down crown and screw caseback. A sapphire crystal protects the dial, while the watch is finished with a 3-link stainless steel bracelet.

Orient F6922 Automatic Movement

The RA-AA0826Y39B uses Orient’s F6922 automatic movement, which also allows hand winding. It provides a power reserve of approximately 40 hours and a stated accuracy of +25 to -15 seconds per day. The movement operates the timekeeping functions as well as the day and date display at 3 o’clock.

120-Click Unidirectional Bezel

A unidirectional bezel with 120 clicks surrounds the dial, incorporating a 60-minute scale for tracking elapsed time. The black bezel provides a clear contrast against the orange dial, while the screw-down crown and screw caseback support the watch’s 20 bar water resistance.

Sapphire Crystal, Luminous Details & 3-Link Bracelet

The sapphire crystal is designed to resist scratches and maintain a clear view of the dial. Luminous material on the hands and hour markers assists with reading the time in low-light conditions. The 3-link stainless steel bracelet matches the case and uses a 20mm lug width. The RA-AA0826Y39B adds the orange colourway to the Kamasu range for Autumn/Winter 2026, while retaining the collection’s established dive-style case and display.
