The Orient RA-AC0F11L (also referenced as RA-AC0F11L10B) is a refined, modern Japanese automatic dress timepiece from Orient’s acclaimed Contemporary Collection. Recognized globally among watch collectors and horology purists by its popular series nicknames—the "Symphony IV", "Symphony 4", or "Contemporary Symphony"—this 41.6mm watch pairs a solid stainless steel case with a radiant sunray blue dial, polished faceted baton hour markers, a framed date calendar window at 3 o'clock, a high-performance in-house automatic movement, an exhibition see-through caseback, a 50-meter water resistance rating, and a genuine leather strap. Designed for modern executives, watch purists, and daily wearers seeking an ideal blend of contemporary dress elegance and Japanese mechanical reliability, it transitions effortlessly from business meetings to formal evening gatherings. The defining visual highlight of this RA-AC0F11L reference is its captivating sunray blue dial face, which catches the light dynamically from deep navy to vibrant cobalt hues. Set beneath a protective mineral crystal, the dial features sleek silver-tone baton indices, sharp dauphine hands, a dedicated outer minute track, and a framed date calendar window positioned cleanly at 3 o'clock. The harmonic contrast between the rich blue dial background, polished silver-tone indices, lustrous stainless steel casing, and dark leather strap delivers a clean, sophisticated presence on the wrist. Beneath its refined exterior, the watch is driven 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 jewels, this self-winding engine provides a 40-hour power reserve, maintaining smooth and accurate timekeeping driven entirely by the natural motion of the wearer's wrist or manual crown winding. The case features classic executive dress proportions, measuring 41.6mm in case width with a slim case profile thickness of 11.7mm and a lug-to-lug distance of 49.0mm, ensuring a balanced, comfortable fit under tailored shirt cuffs. The reverse side features an exhibition see-through screw caseback displaying the internal mechanical movement and decorated oscillating rotor in action. Built for daily wear and light splash exposure, the solid stainless steel case incorporates a push-pull crown and achieves a certified 50-meter (5 bar / 165 ft) water resistance rating suitable for everyday wear, rain, hand washing, and light splashes. The timepiece comes completed on a supple genuine leather strap, secured by a solid stainless steel pin buckle clasp.
