With a new in-house movement and a 50-hour power reserve, the new Mechanical Moon Phase piece is an improved version of ORIENT STAR’s most iconic flagship. It contains a power reserve indicator at 12 o’clock, a semi-skeleton aperture at 9 o’clock, and a moon phase with date display at 6 o’clock. Roman numeral indices and the conventional OS logo stamped pattern are included on the dial. The hour hand has been shortened to prevent it from covering the index marks, and both the hour and minute hands are broader. In order to improve visibility and legibility, both hands’ width balance has been adjusted in steps of 0.01 mm. To prevent glare, the model has sapphire crystal with an anti-reflective coating (SAR coating) on both sides of the glass.
