seeing as no one has posted any worthwhile reply... the vintage watches' value will depend very highly on their condition. main concern is rust. scratched glass/crystal is easily repaired, as is polishing the cases. the dials look fairly legible and i dont see any glaring water damage. I assume none of these are actual gold which of course would make them worth more....
in good working condition i would say you should at least aim for:
$500 for the Heuer stopwatch - first swiss watch in space was a heuer. they also invented the first 1/100th accurate stopwatch ( TAG bought Heuer in the 80s sometime)
$50 Waltham (people collect these for the movement and some sentimental value times long gone)
Bucherer is the tricky one, could be in the $500 range, you would need to be more specific on the movement, model number and year. could be more even.
The rest are pretty much worthless $20 garage sale stuff. Unless the hamilton is an automatic, in which case you could group it with the Waltham.
For a better estimate I would put them up for sale on www.watchuseek.com
and see what bites. That is the most active secondary watch market online
...or I could have just told you they are all worthless and i'd take them all for $50
Alos, keep in mind that $30 in 1960 was the equivalent of $200 in todays money.
