NASA wasn't sure if mechanical watches would survive in space, so all the spacecraft clocks used Bulova Accutron mechanisms, which relied on electrically-sustained tuning forks. Bulova watches flew on a bunch of missions as main and backup watches.
I42: If you think a watch has more value because it's mechanical, fair enough but be aware that there's a bunch of expensive "swiss-made" stuff using movements that sell for less than $10.
