The RE-AU0502S00B is the Orient Star Olympia Calendar Diver Revival — a limited edition of 900 pieces worldwide, each individually numbered on the caseback, reviving Orient’s original 1964 “Olympia Calendar Diver” with the full specification of a modern ISO-rated dive watch. The arrow-shaped hands, three-dimensional cut indices, and sharp-lug case shape are preserved directly from the 1964 original, updated around Orient Star’s in-house Calibre F6N47 with a 50-hour power reserve and a power reserve indicator visible on the silver dial.
The dual-curved sapphire crystal with anti-reflective coating protects the dial with superior scratch resistance and reduced glare. The polished metal unidirectional rotating bezel enables precise elapsed-time tracking. A screw-down crown and caseback secure 200 metres of ISO-standard water resistance for scuba diving. The 41mm stainless steel case with sharp-lug geometry carries the vintage silhouette faithfully, and a stainless steel bracelet completes the package.
Backed by a 3-year Orient Star manufacturer’s warranty under the extended worldwide terms.
Limited to 900 pieces, F6N47 with 50-hour reserve and power reserve indicator, 1964 design DNA, dual-curved AR sapphire, ISO 200m, polished unidirectional bezel, and individually numbered caseback — the Orient Star RE-AU0502S00B is the most thoroughly specified and historically significant diver in the WatchNation range.
