The Vintage Wrist Watch Company has dated this piece to the 1960s.
The watch has a hand-winding movement, a Synchron 40, which is working nicely.

The watch itself measures 34mm diameter excluding the winding crown and the lugs. The case is 18ct gold and there are hallmarks inside the case back for Edinburgh (import mark), with a date letter for 1969 (although it is very small and difficult to read) so it would have been produced during the crossover period between Cyma and Synchron. The case is in good condition, just a couple of minor pin prick indentations to the back.

The lens is in good condition.
The signed dial is in its original finish with original hands, centre seconds and outer minute markers.
A new leather strap has been fitted.
The watch will be sent in a new presentation box.
