This 1978 Omega Seamaster is in new old stock (NOS) condition, completely unworn and free from any signs of wear. Its 35,5mm stainless steel case features a clean silver dial.



Powered by the reliable Caliber 1010 automatic movement, it was serviced in December 2024 to ensure optimal performance for years to come. The watch is entirely original except for its replaced strap, now fitted with a new Dutch calf leather strap in black with a croco-grade motif.



This piece is perfect as a daily wearer, a dress watch, or an addition to any collection, thanks to its pristine condition and classic design.
