A very rare find and gem from the past - Omega Chronograph Cal. 320 Jumbo rose gold.

The Omega Caliber 320 is a highly regarded manual-winding chronograph movement introduced in the 1940s, known for its precision, durability, and elegant design. Today, watches powered by the Omega Caliber 320 are considered collector’s treasures due to their historical significance, technical prowess, and rarity, as production was relatively limited compared to other Omega chronographs of the era.

Our particular watch, comes in a huge Jumbo 37.5 mm rose gold case with crisp case and beveled lugs. Accents like the awesome rose gold syringe hands and hour markers complete the classy look of this piece.

It comes in outstanding condition (we call it museum condition) which you can rarely find on the market.
