··The black sheep in the Spee-ee-eee-eedmaster flockIf a person was to hose the inside of this watch with pure helium and then snap the back on real fast, could his timepiece benefit from the attributes of helium?
I should think that if you hold the watch by the lugs with the dial facing up perfectly horizontal, that if you then place the helium nozzle directly under the opened watch and dispense about 30 ml, that that should be more than enough to float up into the watch and displace all the air. You can then replace the caseback and not have to worry about doing it quickly. Just make sure to keep the watch horizontal. Hope this helps.
