Vintage Omega Seamaster Automatic Sparkle dial Jumbo XL 166.065 - 39mm - 1972

Produced in 1972, this vintage Omega Seamaster features an impressive 39mm case, a size often referred to by collectors as the “Jumbo” or XL Seamaster. The watch is fitted with a beautiful sparkle-effect dial that shifts wonderfully in different lighting conditions, creating a dynamic and eye-catching appearance. The dial remains in great condition, while the case retains most of its original factory polishing. Inside sits the reliable Omega caliber 565 automatic movement, which was overhauled in June 2026 and now runs and functions well. The watch is fitted to its original Omega bracelet, reference 1170, adding to its originality and sporty character. Overall condition is great, making this a fantastic vintage Seamaster and an excellent choice for daily wear.
