Orient Star RK-AY0103L JDM men's automatic watch, blue dial, 41 mm, moon phases, anti-reflective sapphire crystal, SUS316L steel strap, 50-hour power reserve indicator, water resistant to 50 metres (Japanese domestic market)

The new Mechanical Moon Phase piece is a refined version of ORIENT STAR’s most symbolic flagship featuring a new in-house movement with a 50-hour power reserve. It features a semi skeleton aperture at 9 o’clock, power reserve indicator at 12 o’clock, and a moon phase with date display at 6 o’clock. It features a unique flowing water motif on the dial. The colour gradation gives the dial an attractive contrast and sense of depth. The moon phase display depicts the moon gently illuminating a flowing river while the diamond-shaped hands represent the glittering stars. The hour and minute hands are wider, and the hour hand has been shortened ensuring it does not overlap the index markings. The width balance of both hands has been refined in units of 0.01 mm to increase visibility and legibility. The model features sapphire crystal with anti-reflective coating on both sides of the glass (SAR coating) to reduce glare and ensure visibility. The case back is also sapphire crystal while the case and metal bracelet are made of high-quality corrosion-resistant stainless steel (SUS316L). The result is a practical, yet elegant everyday timepiece further enhancing the appeal of mechanical watches.
