this is a beautiful Omega Constellation Chronometer from the mid 1960s with Türler doublesigned cremedial (refernce 168017). All parts about the piece, including crown, hands and bracelet are still the original ones. The 35mm case has never been polished before and appears with supersharp chamfers. The beautiful doublesigned dial in light-creme tone is still in great unmolested condition. The Omega 561 automatic caliber is running great, not being in the need for a service soon. The watch will fit wrists up to 17,7 cm circumference and smaller.
