1. Patek Philippe ref. 2523 two crown world time
Sold for HK$22,300,000
This watch broke the auction record for any wristwatch sold in Asia. The iconic Patek Philippe reference 2523 is the most appreciated, elegant, collectable and sought-after world-time model ever produced by any manufacturer. The dial is fitted with an engine-turned decoration.
So far, only two other yellow gold 2523 models are known to exist with a similar dial, thus making this variation the rarest of them all thanks to its yellow gold case.
