The collection’s flagship, the M34 F8 Date, was developed to showcase Orient Star’s in-house watchmaking system using advanced technologies. The M34 F8 Date’s dial features a traditional design comprising of a three-hand dial of hour, minute and centre seconds, a date display at 3 o’clock. Orient Star’s original power reserve indicators sit at 12 o’clock, while the dial also features a hand-carved pattern depicting Perseid meteor showers. The dial on the RE-BX0004L is further enhanced by the blue colour, depicting the night sky. This captivating colouring, expressive of the deep blue universe, is achieved using Epson's optical multilayer technology, which creates a colour tone effect on a metal plate. The optical multilayer film controls light reflectance and transmittance through multiple layers of nano-thin transparent film, to produce an effect which would not be possible with normal paintwork.Furthermore, due to the dual curved sapphire crystal glass with anti-reflective coating on both sides (SAR coating), the glossiness of the white dial and the intricate pattern on the blue dial can be admired clearly.
