The Orient Star watch collection consists of both classic and sporty models, all of which are manufactured in Japan. From the timeless design and precision parts to their assembly by master craftsmen, Orient Star sets its sights on the stars to create mechanical timepieces of value beyond price. This ambition has been expressed in the brand name on every watch for seven decades. Orient Star craftsmen know that a mechanical watch will simply stop without the love of their owners. That love moves owners to wear the watch and keep its mechanical heart powered, and is inspired by a commitment to excellence passed down since the birth of the brand. With an impressive fusion of timeless design and superior watchmaking, this new Orient Star 43.6mm mechanical sports diver watch delivers several notable features. Complementing its stainless steel band is a sleek blue dial with a 50-hour power reserve subdial, date indicator, and luminous lights on the watch’s hands and a box-shaped index, delivering high visibility in dark areas. Sapphire anti-reflective glass provides additional protection and visibility, while fine knurling bezel offers high maneuverability during diving. Designed with special ring frames securing a high level of shock-absorption, this dynamic watch meets the ISO (International Organization for Standardization) criteria. The sporty RE-AU0302L supports water resistance of 200 meters, ideal for diving and everyday use.
