Oris positions the Aquis Pro 1000M as a fresh expression of its most technical dive watch, designed in collaboration with professional divers to eliminate accidental bezel movement under water through the lockable Rotation Safety System, or RSS, that secures the minutes scale once set as a reliable back‑up to electronic instruments. The watch combines a grey‑PVD‑coated, multi‑piece titanium case measuring 49.50 mm with a ceramic bezel insert, a domed sapphire crystal and a screw‑in security crown to deliver 100 bar water resistance in a package whose materials and geometry are selected for function and durability.
The dial is a blue gradient execution featuring a printed wave structure that adds depth and context without distracting from legibility, a visual cue to the watch’s intended aquatic environment and its extreme rating. Applied indices and hands are generously treated with Super‑LumiNova to ensure instant reading of time in low‑light conditions, while the layout keeps central hours, minutes and seconds unobstructed and the date display discrete yet functional.
Inside is the Oris 733 automatic calibre, with a diameter of Ø 25.60 mm (11½’’’) and a frequency of 4 Hz, delivering central hours, minutes and seconds, a date window with instantaneous change, a date corrector, a fine timing device and stop‑seconds for precise setting. The movement offers a 41‑hour power reserve and runs on 26 jewels, chosen to balance reliability and serviceability for a professional dive context, with the package secured behind a screwed titanium case back bearing special engravings
The case architecture is multi‑piece titanium with a grey PVD coating to reduce glare and wear, anchored by the lockable RSS bezel and a ceramic insert that carries the critical minutes scale used for timing dives. The front crystal is sapphire, domed on both sides with internal anti‑reflective coating, while the stainless steel screw‑in security crown features matching grey PVD, contributing to the 100 bar (1,000 metres) rating alongside a thickness of 16.60 mm, a lug‑to‑lug span of 55.00 mm and an interhorn width of 26.30 mm that suits the robust strap system. The watch is delivered on a blue rubber strap with a grey‑PVD‑coated titanium security folding clasp featuring an extension and quick adjustment, and it is supplied with an additional black rubber strap and a strap‑change tool for user‑friendly swaps.
As a complete professional package, the Aquis Pro 1000M arrives with the distinctive RSS, deep‑rated titanium construction and a highly legible wave‑pattern blue gradient dial, assembled to serve as a dependable, lockable timing instrument below the surface. At a retail price of 3.400,00 EUR/ 3,400 CHF / USD4,100.00 / JPY627,000, the Reference 01 733 7801 7255-Set delivers ceramic‑bezel practicality, dual‑strap versatility with tool included, and a specification set squarely aligned with the needs expressed by working divers.
