Oris Swiss Automatic Calibre 690 (ETA 2836-2 base) circa 1999

37.5mm polished and brushed stainless steel case with a 38-hour power reserve, water resistant to 165 feet / 50 meters. Scratch-resistant sapphire crystal glass with a see-through mineral crystal exhibition caseback, dual push-buttons integrated at 4 and 8 o'clock for rapid timezone adjustment, and a clean, stepped-bezel dress-sport case architecture engineered for cross-continental travel. Classically elegant and intellectually technical on-wrist presence thanks to its deep royal blue dial, fine guilloché sub-register tracking, and polished steel structural lines.

On its matching original Oris polished stainless steel multi-link brick style bracelet featuring a secure folding deployment safety clasp.

A milestone mechanical masterpiece representing Oris's greatest historical complication innovation, housing a highly specialized dual-time automatic movement where the home time is tracked in a independent 12-hour sub-dial at 3 o'clock featuring an integrated day/night window, a continuous sweeping seconds dial with a red pointer hand at 9 o'clock, and an advanced local date window resting at 6 o'clock that syncs and shifts backwards or forwards automatically as you jump timezones.

Watch with box and manual only, original Oris presentation case and model-specific Calibre 690/695 instruction booklet included, official warranty registration cards absent. Excellent pre-owned physical condition with sharp factory case contours, zero dial fading, and minimal bracelet slack
