This reference (165.001) features a significantly thicker gold layer ("Plaqué Or G 40"), which gives the watch the weight and deep luster of a solid gold piece without the solid gold price tag. The plating remains in exceptional condition. ​Condition Report: ​Movement: Fully Serviced (04/2026). Running strong with high amplitude. The copper-toned finish on the bridges is bright and untarnished. ​Dial: Original champagne dial with a beautiful, even "stardust" patina. Features applied gold markers and the iconic Omega logo. ​Case: Crisp edges with very little wear to the 40-micron plating. The stainless steel case back features a sharp, well-defined Seamaster Seahorse logo. ​Crown: Original Omega-signed crown. ​Crystal: Original Omega signed acrylic. ​Strap: New Paired with a high-quality handmade Italian leather strap. ​Seller’s Note: Finding a vintage Seamaster that has both the rare 40-micron hallmark and a documented fresh service is a rarity. This watch is an investment piece that combines mechanical reliability with timeless mid-century elegance.
