Omega Seamaster 1000m Professional “The Grand” 1976



Very rare Omega Seamaster Professional 1000m ref. 166.093 from 1976–77. Sn. 388XXXXX. Original blue Mk1 tritium dial and hands, in very good condition. Original B2 black bezel, in good condition.

Omega cal. 1012 automatic movement was serviced by us a few years ago. Movement is working very well. The watch’s original steel case is possibly unpolished. It shows some signs of use, but is still in excellent condition. New Omega off-shore mesh steel bracelet ref. 1247-237.

The watch comes in a new wooden box, no original box/documents. The case is still diving proof, tested at +10/-0.7 bar.


This Omega Seamaster Professional Plo-Prof 1000m is very rare. The first series of about 150 pieces with the cal. 1002 movement was made in 1972, and the next series of about 300 pieces was manufactured in 1976. In addition to these 450 pieces, Omega is known to have manufactured a few dozen prototype models. This would bring the total number to just under 500 pieces, including all different versions.

50 pieces from the first series of Seamaster 1000m watches were delivered to the Monaco Oceanographic Research Institute. The leader of the institute at the time, Jacques Cousteau, gave the first of these watches as a gift to Rainier III, the Prince of Monaco.

We acquired this watch from a significant Finnish watch collection
