Thanks, all 3 are perfectly working all 3 are hand-winding watches.Looks like you have 3 watches, a Bulova, a Voltaire and a Crusader. Look 1950s-60s? (at least) 2 of them are automatics. If you take them in for a service they might be usable. Depending on your location and watchmaker, service might cost around $150 per watch.
If you put new straps on them they would look nice.
This might be relevant for the Bulova
