welcome to RG wozzaa

the california is a sweet looking panerai.

1) you can service the movt.. that should give it a long time of trouble-free timing. and don't use the chrono functions!! i know it's there and very tempting, but without a service.. you're just asking for trouble!

2) service on an asian chrono? i would say at least 4years.. ( i wouldn't service it now, whenever it stops working just send it to a watchsmith)

3) yes it can be manual wound until it starts moving again, or you can swirl the watch until it starts up again.. (that's why i worry that if it's not service, manual winding an asian movt out of the box, can lead to it breaking faster)

4)it doesn't matter... if you don't use the watch often, it might last longer... but that's not why you bought it!! wear ittt


hope this helps mateeeeeeeee
