Omega Swiss Automatic Chronograph Calibre 3313 circa 2007

45.5mm brushed and polished stainless steel case with a 52-hour power reserve, water resistant to an incredible 2,000 feet / 600 meters. Domed scratch-resistant sapphire crystal glass with multi-layered anti-reflective treatment, a solid screw-down caseback crisply stamped with the large Seamaster Hippocampus medallion, matching steel-rimmed chronograph pushers, a manual helium escape valve at 10 o'clock, and an overbuilt, ultra-rugged case architecture engineered for heavy deep-sea utility. Formidable and masculine on-wrist presence thanks to its deep matte black dial, high-contrast silver sub-dial tracking rings, and highly technical tool-watch symmetry.

On matching original full-length brushed stainless steel three-link bracelet featuring a secure fold-over deployment safety clasp with an integrated diver's extension.

The definitive first-generation modern Planet Ocean Chronograph flagship housing a high-performance column-wheel automatic movement with Co-Axial technology, featuring iconic broad-arrow hands, luminous Super-LumiNova® hour markers, white Arabic numerals at 12, 3, 6, and 9 o'clock, a vibrant orange-tipped central chronograph needle, and a calendar window neatly positioned between 4 and 5 o'clock.

Full Set, with original red Omega leather presentation box, cream leather cardholder wallet, operating instructions booklet, pictograms card, chronometer certificate, and original international warranty card legibly signed and dated February 2007. Excellent, exceptionally clean pre-owned physical condition with razor-sharp factory case lines, clean bezel printing, and minimal bracelet slack.
