I have strayed here from f10 as I would like to find out all I can about a friends Lonex heirloom.
I have searched older threads here for information and generally on google. All I can find out about Lonex is that they were a brand name registered by Rolex along with many others.
Here is the watch in question...
As I understand Rolex started no earlier than 1920, I'm surprised this style of pocket watch does not pre-date that.
The only movement marks I can see are on the Crown Wheel and Ratchet Wheel. "Swiss Made" "Lonex 15 Jewels"
The case is gold filled - the watch all looks in good shape and well made.
Any help would be appreciated, especially about the movement as the main spring is broken and will need replacing.
