Here is link to a nice little video about the watches Robert Loomes supplied to a Royal Gurkha Regiment expedition to climb Everest.
I imagine there is a special connection between the Smiths movements, that Loomes modifies for their watches, and Edmund Hilary Everest expedition.
Subsequently the expedition have been caught up in the earthquake disaster. You can follow there progress on the Robert Loomes website.
