The Vintage Wrist Watch Company has dated this piece to the 1950s.
The watch has a chronometer grade movement, calibre 10BP, which is working nicely.
The movement is also stamped with the word isochronism which means that a balance that takes the same time to complete a swing no matter how big the swing is, has the property of isochronism. Although not officially certified as being of chronometer status, the quality is certainly there and would no doubt have been certified as such had it been Swiss. The movement is fully signed and the date code dates it to 1957.

The watch itself measures 32mm diameter excluding the lugs and the winding crown. The case is 10k white gold filled and it is in good condition. The date code on the case is 1958 so that ties up nicely with the movement as we would expect a slight variation as the movement and cases would have been made in different factories.

The lens is in good condition.
The signed dial is in its original finish with original hands, a subsidiary seconds dial and “jewels” at 3, 9 and 12.
A new leather strap has been fitted.
The watch comes in a 1950s Bulova presentation box.
