We all know that the Speedy Pro was the 1st watch certified for manned space flight and either the Smiths or Explorer (depends who you believe) were 1st to the Everest summit but aside from these how likely is it that a 'normal' watch would survive on the Everest peak or on the moon.

Presumably a Gshock would lap it all up no problem but is there any reason why an El Primero wouldn't survive Everest? Or why a Dornbluth (would need to be manual wind or quartz I presume) wouldn't survive a trip to the moon's surface?
