Ursprüngliche Beschreibung

Produced in 1968, this beautiful Vintage Onega Constellation Chronometer DayDate offers a incredible combination of complications. The watch features a day date function at the 3 o’clock position, with the weekdays displayed in Portuguese.



The linen dial provides wonderful texture and depth, perfectly complemented by the rose gold plated case and its riveted bezel. Inside, the chronometer-certified caliber 751 automatic movement was overhauled in March 2026 and now runs and functions well.



We have paired this piece with a high-quality brown leather strap with a crocodile motif and a light glossy finish, which suits the warm rose gold tone beautifully. The crown shows clear fading on the side, yet remains original and has therefore been left untouched, though it could be replaced later if the new owner prefers.



Overall, the condition of this piece is good. It will make for a beautiful and refined dress watch.
