Inspired by the Orient Calendar Auto - one of Orient's first dive watches, launched in 1964 - the ORIENT STAR Sport RE-AU0602E watch is built for wrists that crave underwater adventure. Water-resistant to 20 ATM, this impressive timepiece features a premium high-grade stainless steel case SUS316L. A rotating aluminum bezel reinforces its diving credentials. The watch also features a screw-down caseback and a crown at three o'clock. To withstand water pressure, Orient Star fitted it with a domed sapphire crystal complete with an anti-reflective coating. Don't wait - this is the practical, stylish dive watch you've been looking for.
Inspired by the Ryusendo Cave in Iwate Prefecture, Japan - regarded by many as one of the most beautiful and mysterious limestone caverns in the world - this dial boasts a stunning green hue and exceptional luminosity. The perimeter is lined with hour markers of varying sizes and shapes, all treated with luminescent technology so they remain visible even in the depths. The same coating is applied to the three central hands. A date window at three o'clock makes this watch a true everyday essential. The brand name, movement type, and water resistance rating are printed just above the six o'clock position.
The ORIENT STAR Sport RE-AU0602E runs on an automatic movement - specifically the caliber F6N47, delivering an impressive 50-hour power reserve. The seconds hand sweeps at 6 beats per second, driven by a frequency of 21,600 vibrations per hour. You can also wind the movement manually via the crown. A hacking seconds feature allows for precise time-setting.
Completing the sporty look, a 316L stainless steel bracelet with five rows of polished links wraps comfortably around your wrist. A silver-toned deployant clasp keeps it secure. As a bonus, it features a diver extension so you can wear it over a wetsuit.
With a water resistance of 20 ATM (200 meters), this model earns the title of "dive watch" without hesitation. Our watchmaking experts agree: it handles showers, baths, lap swimming, freediving, and recreational scuba with ease - but extreme deep-sea diving is beyond its specs. For professional divers pushing serious depth records, we recommend models rated at 30 ATM or higher. Also: never operate the pushers or crown while underwater, to maintain a perfect water-tight seal.
