A ruby and diamond “Cocktail” Watch Ring by Cortébert, c.1950’s in 18ct rose gold. The dial is covered by a pierced, circular set of gold rays set with a brilliant cut diamond in the center and small cabochon rubies that surround the outer edge. The cover is hinged to reveal a white dial with lozenge-shaped dial markers, and a Cortébert marked dial. It is a sixteen jewel lever movement with Swiss marks.
Cortébert, a Swiss watch company founded in 1790 in the town of Cortébert, Switzerland, was considered to be a maker of high quality watches in addition to a supplier of movements to Rolex.
The ring is beautiful on the hand and is truly a unique piece that you won’t see on anyone else. We have had the movement serviced by an expert watchmaker and it is in working order.
