A 75th Anniversary Model Reflecting the Beauty of the Aurora

This 75th anniversary model expresses the aurora with a green gradation dial. The rose gold-coloured accents on the rim of the semi skeleton at 9 o’clock, the crown, the dots on the outer periphery of the Roman numerals, and the OS mark all lend a soft touch to this watch.

A Model Combining Practicality and Beauty

The case with reinforced water resistance for everyday use is combined with a metal bracelet made of high-quality stainless steel (SUS316L). The words “Orient Star 75th Anniversary” and limited-edition serial number are engraved on the see-through caseback.
