I found this stop watch in an estate sale of a retired watchmaker. It was in a box full of parts. Im hoping the crown is somewhere to be found, can someone post an image of what it looks like?

How do I get to the movement? When I remove the case back I get to this sticker on a brass cover plate, but can't figure out how to remove it.

he inside of the case back is labeled:
Heuer-Leonidas SA
SWISS

Not sure on this one. It's a 1/5th Second Chronograph..likely from early 1960s

Heuer Timer Corp. was established in 1959 and left New York in 1970 for New Jersey
