The pinnacle of Japanese watchmaking: Art, astronomy, and mechanics on full display.

The Orient Star RE-AY0106S is a masterpiece from the Classic M45 collection, designed for those who appreciate high-end watchmaking complications. This flagship model achieves perfect balance on its dial by combining three masterful displays: a Semi-Skeleton window at 9 o’clock revealing the beating of its escapement, a power reserve indicator at 12 o’clock, and the Moon Phase with date complication at 6 o’clock.

The readability of this piece has been taken to an obsessive level: the sword-shaped hands have been redesigned and balanced to 0.01 mm precision to ensure perfect symmetry and prevent them from obscuring the elegant Roman numerals. With a white dial subtly engraved with the classic Orient Star pattern and a strap of genuine black Cordovan leather, this watch exudes the same timeless elegance as a perfectly executed classical melody.

✨ Key Features

• Trilogy Dial (Semi-Skeleton + Moon Phase): Visually enjoy the movement of the rubies through its openwork window, while monitoring the moon’s cycle and the watch’s remaining power reserve.
• Micrometric Hand Adjustment: Meticulously redesigned to the hundredth of a millimeter to improve visibility without obstructing the Roman numerals.
• Sapphire Crystal with SAR Coating: Equipped with dual-curved sapphire featuring super anti-reflective treatment on both sides of the crystal, making it appear invisible under light.
• Premium Cordoban Leather Strap: Mounted on a Cordoban leather strap (one of the world’s most exclusive, durable, and lustrous leathers) with a three-fold deployant clasp.
• F7M62 Manufacture Caliber: High-end Japanese automatic movement with a 50-hour power reserve, seconds stop, and sapphire case back to admire its decorated rotor.
