Hi. My 7 year old Nettuno 3 has been going fast and I mean fast within one day up to one minute fast when worn, and it slows down when not worn up to 30 seconds overnight. Might I ask what part of the watch is wrong or needs replacement? My watchowner friend says it is the balance wheel. Is he correct in saying so? I have already tried regulating but still goes fast and slow when worn and not worn.

There are differences in how fast (or slow) a mechanical movement runs based on position, which you can use to your advantage. For example, if it loses time during the day when on the wrist, put it on the nightstand during the night in a position where it gains time.

Our grandparents knew all about it and used it to achieve great accuracy with old, mechanical movements and watches.

Having said all that, if your watch is 7 years old, you might want to get it serviced. It probably just needs a good cleaning and lubrication, might need some demagnetizing as well.

Are you having the WR checked annually?

Cheers

Matt
