Orient Star Classic Mechanical Moon Phase Limited Edition, Reference RE-AY0116A

Orient Star has launched a new Mechanical Moon Phase model from its Classis collection. Popular for its original mechanical watch design and high-performance in-house movement, Mechanical Moon Phase unveils a new simple moon phase design featuring a coloured dial by omitting the openwork.

The much acclaimed Mechanical Moon Phase watch stands out with ingenious design elements such as Orient Star’s iconic power reserve indicator at 12 o’clock, semi-skeleton window at 9 o’clock that shows the inner workings of the mechanical movement, and the moon phase mechanism at 6 o’clock with a date hand and date display.

In 2021 celebrating the 70th anniversary, Orient Star released Mechanical Moon Phase featuring an elegant and subdued ivory dial without openwork, while inheriting classical design codes such as the Roman numerals, railway track scale and highly legible leaf-shaped hands. This model made by requests of fans preferring a dial without openwork was available exclusively in Japan for the first time.

The theme of this new model evokes the elegance of time flowing in Japanese nature and features a beautifully coloured dial inspired by the moon reflected on Lake Tazawa in Akita Prefecture. Incorporating white mother-of-pearl and grey gradation, this model is available in a limited edition of 200 pieces.

The dial features a silvery moon in the night sky and a grey date indicator ring, three-dimensional printed Roman numerals, a black ring separating the dial and the transparent OS logo printed on the dial like a watermark.

The dual curved sapphire crystal with anti-reflective coating on both sides allows the wearer to view all these details clearly.

The automatic mechanical in-house caliber F7M65 offers a power reserve of 50 hours as well as stable high accuracy of +15 seconds to -5 seconds per day. The beautiful finishing of the 46-F7 series movement can be admired through the sapphire crystal see-through case back.
