The Orient RA-AC0F01B (also referenced as RA-AC0F01B10B / AC0F01B) is a sleek, versatile Japanese automatic dress watch from Orient’s renowned Contemporary Collection. Recognized among watch collectors and style enthusiasts by its series nicknames—the "Symphony III" or "Contemporary Date"—this 41.6mm timepiece pairs a solid stainless steel case with a multi-textured matte black dial, a date calendar window at 3 o'clock, an in-house automatic movement, an exhibition see-through caseback, a premium sapphire crystal, and a solid stainless steel construction. Designed for modern gentlemen who appreciate classic dress watch elegance, reliable in-house mechanical watchmaking, and everyday versatility, it transitions seamlessly from formal business meetings to evening attire. The defining visual highlight of this RA-AC0F01B reference is its refined black dial face framed by a slim, polished stainless steel bezel. Set beneath a scratch-resistant sapphire crystal, the dial features sleek silver-tone baton hour markers, sharp dauphine hands with polished facets, and a clean calendar date window positioned at 3 o'clock. The monochrome contrast between the deep black dial background and radiant silver indices delivers an understated, sophisticated aesthetic on the wrist. Beneath its refined exterior, the watch is powered by Orient’s reliable in-house Caliber F6722 automatic mechanical movement with hand-winding and second-hand hacking capabilities. Operating at 21,600 vibrations per hour (3 Hz) across 22 synthetic jewels, this self-winding caliber delivers a dependable 40-hour power reserve with a daily precision rating of +25 to -15 seconds per day. The well-proportioned round housing measures 41.6mm in case width (49.0mm lug-to-lug) with a profile thickness of 11.7mm and a 22mm lug width, offering an ergonomic, shirt-cuff-friendly presence on the wrist. Dial protection is provided by a premium scratch-resistant sapphire crystal for long-term clarity. The reverse side features a screw-down exhibition see-through caseback that exposes the operating mechanical movement and Orient-branded rotor. Built for daily wear, the stainless steel case achieves a certified 50-meter (5 bar / 165 ft) water resistance rating to protect against rain, splashes, and daily exposure. The timepiece comes completed on an integrated stainless steel link construction, secured by a solid tri-fold deployment clasp with a push-button release mechanism.
