Orient Star M45 F8 Mechanical Moon Phase Hand Wind RE-BW0004S00B Men's Watch
The Orient Star M45 F8 Moon Phase represents the most refined expression of Japanese mechanical watchmaking within the M-Collection. Inspired by the Pleiades star cluster, it combines classical design with modern precision.
At its core is the in-house F8A62 hand-wound movement, offering an impressive 70-hour power reserve and exceptional accuracy.
The dial is where this piece truly stands apart. Featuring layered textures, applied indices, and a beautifully executed moon phase display, it delivers depth and elegance with every shift in light. Select models within the M-Collection utilise advanced dial manufacturing techniques developed in Japan to achieve this level of refinement.
Finished with a dual-curved sapphire crystal and a slim, dress-focused case, this is a watch designed for collectors who appreciate understated craftsmanship.
