Vintage Omega Constellation Calendar Crosshair Chronometer on Mesh 2943-1 SC - 35mm - 1958

This vintage Omega Constellation Calendar, produced in 1958, is among the first Constellation production models. It features a white dial with light patina speckles and golden accents, housed in a 35mm wide gold-plated case. The watch is paired with a gold-plated, mesh bracelet that complements it perfectly. For those who prefer a different style, a black calf leather strap is also included.

Inside is the caliber 504 automatic movement, serviced in October 2025, which currently runs and functions well. The watch is in good overall condition and remains entirely original, except for a freshly replaced glass. The crown shows heavy fading but is original, preserving the watch’s authenticity.

This is a charming collector’s piece and an elegant vintage dress watch.
