Orient Star has launched a new M45 F7 Mechanical Moon Phase model from its Classic Collection M45. The new cutting-edge dial, inspired by the mystical M45 Pleiades star cluster that lights up the night sky, features a new grey gradation effect representing an occultation, or overlapping, of Pleiades and the moon.

Orient Star launched the Classic Collection M45 in 2023, inspired by the Pleiades star cluster that mysteriously lights up the night sky. The Mechanical Moon Phase model with blue gradation dial, released in October of the same year, caused a sensation for its truly cutting-edge design. The latest M45 F7 Mechanical Moon Phase model takes this innovative design further by expressing the Pleiades and the moon shining in the night sky.

Like the blue dial of earlier models, the new grey gradation dial is created using the same complex manufacturing processes and advanced technologies. The surface of the dial is first stamped with patterns representing the infinite stars of the M45 Pleiades, which refers to the open star cluster of Taurus. The delicate patterns change expression depending on the angle of the light 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. This technique creates monotones that change from grey 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 grey gradation dial the depth of the eternally expanding universe.

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 grey plated hour and minute hands blend in with the grey gradation of the night sky, while the mirror and hairline finishes add legibility. The silver-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 to express the night sky. Each of the 120 limited edition pieces in this rare design are engraved with a serial number.

The moon and star clusters give the M45 F7 Mechanical Moon Phase a touch of mystique, while the monotoned grey gradation conveys the abyss of the night sky, inviting watch lovers to experience the concept of time on a cosmic level.
