The Orient Star M45 F8 Mechanical Moon Phase Hand Winding RE-BW0005N00B Limited Edition combines refined Japanese watchmaking with a beautifully restrained moon phase design inspired by the Pleiades star cluster and the moon. Limited to just 140 pieces, the watch presents a mystical grey gradation dial that shifts from grey at the centre to black towards the outer edge, creating a quiet sense of depth and night-sky atmosphere.
The 39.5mm stainless steel case is crafted from corrosion-resistant SUS316L stainless steel and has a slim 11.9mm profile, giving the watch an elegant and comfortable presence on the wrist. The dial features a stamped pattern expressing countless stars, silver-coloured dots representing the brightest stars in the Pleiades, and Roman numerals built up through multiple rounds of pad printing for added depth.
At the heart of the watch is Orient Star’s in-house F8A62 hand-winding mechanical movement, offering over 70 hours of power reserve, 20 jewels, and an accuracy rating of +15 to -5 seconds per day. The movement also features a silicon escape wheel developed in-house, visible through the see-through sapphire crystal case back.
The moon phase display features a glossy finish, scattered stars, and a gently shining moon made from white mother-of-pearl. Protected by a dual curve sapphire crystal with SAR coating, the dial remains clear while reducing glare. Finished with a black cordovan leather strap and trifold deployant buckle with push button, the RE-BW0005N00B delivers a refined blend of craftsmanship, exclusivity, and elegant mechanical artistry.
