Orient Mako Kamasu Men's Dive Watch RA-AA0812L39B
The Orient RA-AA0812L39B brings together serious diving capability with refined mechanical watchmaking. Its 41.8mm stainless steel case provides a substantial yet wearable presence. The deep blue dial features high-contrast applied indices, robust luminous hands and a day-and-date display for added practicality.
In-House Automatic Movement
Powered by Orient’s in-house Calibre F6922, the watch supports both hand-winding and hacking seconds, enabling precise adjustment and good mechanical reliability. With an approximate forty-hour power reserve, it offers dependable performance for everyday wear.
Built for Performance
Designed with active use in mind, this model offers 200-metre water resistance, a screw-down crown, and a sapphire crystal for enhanced durability. The unidirectional 120-click bezel and 22mm lug width contribute to its dive-watch functionality and balance.
Style Meets Practicality
Finished on a stainless steel bracelet secured by a fold-over clasp with safety, the RA-AA0812L39B transitions effortlessly from aquatic excursions to smart-casual settings. Its combination of mechanical integrity, solid construction and bold design makes it a standout choice for those who appreciate both function and style.
