I mean, did you really think I wasn't going to kick this off with a ref. 2526? This is without question my personal favorite Patek Philippe reference of all time – it's automatic, waterproof, and about as perfectly balanced aesthetically as any man-made object can be. We've seen quite a few double-signed examples over the last year or two and they tend to bring in big money. This watch likely won't be a record setter, but it's in great honest condition, the case has taken on a really warm color, and the double-signed Gübelin dial looks to be in outstanding condition. If you want to learn more about this reference in general, check out Ben's in-depth story here.

This watch is Lot 64 and it carries an estimate of $20,000-40,000.
