The Vintage Wrist Watch Company has dated this piece to the 1960s.
The watch has a automatic movement which is working nicely. The movement is fully signed and it has the serial number 5597587 which dates it back to 1968.
The watch measures 33mm diameter excluding the winding crown and the lugs.
The screw-on case back is stainless steel and it is signed inside with the Eterna name.

Eterna winding crown with the Eterna ball bearings logo. The plate has worn off the end of the crown.
The lens is in good condition (some reflection showing in the photos).
The signed dial is in its original finish. There is a little “pin prick” mark just above number 4 and general light marking but overall not too detrimental. Quickset date (initially set by repeatedly pulling the winding crown until the desired date is reached).
The dial is not original to the watch although of the correct age.
A new leather strap has been fitted.
The watch comes in a new presentation box.
