Vintage Omega Constellation Chronometer Automatic Ultra Thin 167.021 - 33mm - 1966

This vintage Omega Constellation was produced in 1966. It features a beautiful white dial with black lacquer hour markers sandwiched by golden sides, with all other dial details executed in black. The gold plated case measures 33 millimeters in width and is only 8.6 millimeters thick. Inside is the Caliber 712 automatic movement, the slimmer successor to the 500 series, which was overhauled in February 2026 and currently runs and functions well. We have chosen to pair this watch with a black top grain leather strap with a crocodile motif, which we believe suits the watch very well. The watch remains entirely original except for this brand new leather strap. Overall, the condition is very well.
