Vintage Omega Seamaster Cosmic 2000 Automatic 166.0128 - 38mm - 1974 Box + Tag

This beautiful Omega Seamaster Cosmic 2000 was produced in 1974 and remains in magnificent original condition. It features a white dial with a vertically brushed motif, preserved almost perfectly, with only a tiny speckle above the Omega logo. The case retains its original polish exceptionally well, and the case back still shows remnants of the original purple factory sticker.

Inside sits the Omega caliber 1012 automatic movement, serviced in June 2026 and now running and functioning excellently. We’ve paired the watch with a top grain leather strap with a crocodile motif.

What makes this example especially desirable is that it comes complete with its original box and tag. The tag still shows the caliber number, serial number, reference number, and even the original retail price of $110, equivalent to approximately $790 today when adjusted for inflation.

Overall, this is a superbly preserved Seamaster Cosmic 2000 and a true collector’s piece.
