The Orient Star RE-AY0005A from the Contemporary collection combines refined Japanese mechanical watchmaking with a celestial-inspired design. Featuring a beautifully crafted mother-of-pearl dial, blued hands, and multiple mechanical complications, the watch reflects Orient Star’s philosophy of blending technical precision with artistic dial work.

Elegant Mother-of-Pearl Dial with Blue Hands

The dial is crafted from natural mother-of-pearl, showcasing delicate organic patterns derived from pearl oyster shells. This material produces a subtle iridescent shimmer that shifts under changing light, creating a dial that appears slightly different from every angle. The natural depth of the material enhances the watch’s three-dimensional visual effect, giving the dial a refined and luminous character.

Contrasting beautifully against the pearl surface are the IP-coated blue hands and hour markers. Their deep metallic blue tone provides excellent legibility while adding a sophisticated colour accent that complements the dial’s soft white tones.

The layout follows a poetic astronomical theme:

  • The moon phase display at 6 o’clock represents the Moon.

  • The semi-skeleton open-heart aperture at 9 o’clock symbolises the Earth and reveals the oscillating balance wheel.

  • The power reserve indicator at 12 o’clock adds both symmetry and practical functionality.

Together, these elements create a layered and visually engaging dial that highlights the mechanical nature of the watch.

In-House Mechanical Movement

Inside the watch is the Orient Star Calibre F7M63, a Japanese in-house automatic movement designed for stable precision and reliability. The movement provides a power reserve of approximately 50 hours, along with manual winding and hacking seconds for precise time setting. The movement can be admired through the sapphire exhibition caseback, allowing a view of the mechanical craftsmanship within.

Case Dimensions and Build

The watch is housed in a refined stainless steel case with balanced proportions suitable for both formal and everyday wear.

Case specifications:

  • Case diameter (3H–9H): 41 mm

  • Lug-to-lug length (12H–6H): 48.5 mm

  • Case thickness: 13.1 mm

  • Weight: approximately 155 g

The case and bracelet are made from SUS316L stainless steel, finished with refined polishing techniques including Sallaz polishing, producing a distortion-free mirror finish on key surfaces.

A sapphire crystal with super anti-reflective coating protects the dial, ensuring excellent clarity while minimizing glare.
