Does JLC do the 1000 hour test on time pieces when they go in for a complete overhaul?
The service center tells me
We
perform a test that isn’t exactly a 1000 hour test, but is the exact
equivalent during our quality control process and saves time in order
not to hold a client’s piece
for those amount of testing days which would be roughly a few weeks or
so of testing if the 1000 hr. test were to be performed.
