That sounds good - the prospect that the watch may not need a servicing for 20 years, though this is on a brand new watch, and it DID need a service at 20 years.
Considering the watches I'm looking at are already 20-30 years old... Does this imply that the things start wearing out eventually? I mean, it sounds like a car - after 20 years they tend to erode pretty quickly. Some people pass their old cars on to the next generation, but I'm not in the mood to give my son a broken watch.
I say this in part because Audemars Piguet also states their service prices, but they caveat that the rates only apply to watches of 25 years or less! Patek states pretty clearly "these are maximum public prices", which is reassuring. Piguet's means to me: 25 year warranty. I'll need three just to get me through my own lifetime, never mind my kid's!
This in mind - anyone have experience with old Pateks, say, for example, a repairman saying "Oh well, it's really old a lot of parts are blown out" or "it took forever to fix, so I had to charge double" ... ?
