Orient Star has released a model from the M45 collection—the M45 F7 Mechanical Moon Phase. The M45 is an Orient Star collection, named after the star cluster M45 Pleiades, which has fascinated people around the world since ancient times. Continuing the universal design inherited from the original Orient Star, this limited-edition model of 80 pieces, features a striking, blue gradation dial expressing the mystical star cluster that colours the night skies.

Established in 1951, Orient Star originates from a desire to create timepieces that would become “shining stars.” For more than 70 years, this desire has been reflected in the beautiful and unique designs, and the movements which showcase the distinct appeal of mechanical watches.

The M45 F7 Mechanical Moon Phase, is named after the M45 Pleiades, known as the Seven Sisters, and refers to the open star cluster of Taurus observed in the eastern skies in early winter. With its white light tinged with blue, it has been used to mark the time and seasons, and its beautiful scenes are mentioned in a passage from the Pillow Book, a collection of essays written in the mid-Heian period more than 1,000 years ago in Japan.

Complex manufacturing processes and advanced technology are characteristics of Orient Star dials, and in this model, the surface of the dial is first stamped with patterns to represent the infinite stars. The delicate patterns change expressions depending on the angle from which light enters and create a scene of twinkling stars on the dial. Next, uniquely formulated paint is applied using a gradation machine to delicately adjust the colour density and width, creating tones that change from blue at the centre of the dial to black towards the outer edge. The painted surface is then coated with wrapping that is thicker and more transparent than normal clear coating, giving the blue gradation dial the depth of the night sky.

The power reserve indicator at 12 o’clock and the moon phase, date hand and date display at 6 o’clock, are designed in a dual-plate structure. The black Roman numeral indices, which match the colour of the dial’s outer rim, are printed in multiple layers to form exquisite contour and shading, distinguishing them from the background. The vapour-plated blue hour and minute hands blend in with the night sky, while the mirror and hairline finishes add legibility. The gold-coloured accents by the index and power reserve are reminiscent of the stars shining particularly bright in the M45 Pleiades. The case is made of high-quality stainless steel (SUS316L) and set off with deep black plating.
