If you run your char till server restart and wait for the "Server connection lost" message you will find the status of your weapon/gear in the same condition when you logged in.
Example: You start farming with 100/100 status and continue playing where your weapon wears out to 30/100 just before the server restart you will find it at 100/100 just after the server restart when you log in again.
I tested it it does not work with Alt F4
