I have a Lorier Falcon S3, and the O-ring has suddenly started sticking out for no apparent reason.
I’m certain the watch arrived from the factory in perfect condition, but now part of the gasket is protruding from the case back.
Could this indicate a more serious problem, or is it something my local watchmaker can easily fix?
I live in Spain and would prefer not to send the watch to the service center.
Thanks!
