Lot Essay

Accompanied by an OMEGA Extract from the Archives confirming production of the present watch in 1974 as a Prototype.

As a prototype, this watch is extremely rare. Manufactured after the Mark IV and before the Mark V designs, this prototype was marked by its hand engraving of 162 under the balance as well as underneath the lower left lug- a way for OMEGA to distinguish pre-series products at the time.
