This vintage Omega Speedmaster Professional Moonwatch, produced in 1983, nicknamed the ''Long S & R'' features the caliber 861 manual-wind movement (Serviced in October 2025) and the original tritium dial, with its patina’d hour markers and the two dots at 12 o’clock. The bezel remains well-preserved, the dial shows no wear, and the black lacquer in the caseback engraving is fully intact. Both case and bracelet are in great condition, with only minor scratches barely visible to the eye. It comes on the original Omega Speedmaster bracelet reference 1171, still long enough to fit wrists from 17 to 20,5 cm, making it suitable for medium to large wrists. Overall condition is incredible.
