Longines Grand Prize Automatic Wrist Watch
Features a lovely pristine dial with cool Longines folding numerals
I do not have the case opener for this watch, but the sales tag indicates a Longines 430 movement from 1962

The watch was serviced when I purchased in at a NAWCC show around 8 years ago
Runs well with no issues
The only drawback is the crown has wear but not that noticeable and easily replaced if you so desire

Teju strap was new at the time and I rarely wore the watch (which is why I am selling) and it is in good shape

Thanks for looking
