You’ll find many distinguished brands of watches at Christie’s watch sale on December 16th, but as is the case so often these days, the top ten estimated timepieces are all from one manufacturer: Patek Philippe. Of those, a rare 18k gold perpetual calendar keyless lever chronograph clockwatch with sonneries and moon phases is expected to be the most valuable, with an estimate of $350,000-$550,000.
An 18k gold Patek automatic minute repeating wristwatch is expected to be almost as valuable. Produced circa 1997, it’s estimated at $300,000-$500,000. Completing the lineup for the top five estimated timepieces are a 1956 18K gold two train, minute repeating open face calendar pocket watch with moon phases that’s described as “probably unique” ( $250,000-$350,000), a 1954 18k gold perpetual calendar wristwatch with center seconds and moon phases (est. $250,000-$350,000), and an 18k pink gold perpetual calendar wristwatch with moon phases manufactured in 1956 ($250,000-$350,000).
