ORIENT STAR Mechanical Moon Phase New Models

ORIENT STAR has added four new models to its popular Mechanical Moon Phase Classic Collection with the introduction of the “New Look Original” and “Next Generation” models. The new pieces update the Mechanical Moon Phase, first released in 2017 and now one of the brand’s most iconic designs.

The “New Look Original” model is a refined version of ORIENT STAR’s most symbolic flagship, while the “Next Generation” brings sophisticated design elements with a new flowing water motif on the dial and diamond-shaped hands. Both models feature a new in-house movement with a 50-hour power reserve based on caliber 46-F7, an evolution of the caliber 46 series launched in 1971. The result is a practical, yet elegant everyday timepiece further enhancing the appeal of mechanical watches.

The four new Mechanical Moon Phase pieces feature 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. The unique design and high-quality mechanical movement have made the Mechanical Moon Phase one of ORIENT STAR’s most-loved models worldwide.

The “New Classic” with a moon phase display, power reserve indicator, and reliable high accuracy of +15 seconds to −5 seconds per day, now has 50 hours of power reserve with the in-house caliber F7M62, part of the 46-F7 series The detailed finishing and beautifully embellished movement can be seen and admired through the sapphire crystal case back. The “New Look Original” maintains the symbolic design of the original Mechanical Moon Phase while adding further refinements and incorporating an upgraded range of basic functions making it perfect for everyday use.

The dial features Roman numeral indices and the traditional OS logo stamped pattern. 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 “Next Generation” is the first Mechanical Moon Phase to feature a unique flowing water motif on the dial. The soft curves of the stamped design that expand towards the edge of the dial and its Roman numeral indices are suggestive of a flowing river in shades of navy and grey.

The colour gradation gives the dial an attractive contrast and sense of depth. The hour and minute hands are dauphine shaped with brushed and mirror finishing, and the redesigned tips of the hands are diamond-shaped accented with colour for clarity. The moon phase display depicts the moon gently illuminating a flowing river while the diamond-shaped hands represent the glittering stars.

There are two “New Look Original” models, both with a white traditional dial, and two “Next Generation” models with a navy and grey dial and flowing water motif. All models feature 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 strap incorporates cordovan leather often found in high-quality watches and is designed to be worn and loved for many years to come.
