On July 16, Sotheby’s in London is staging a stunning sale of Important Watches. The top lots are all of course Patel Philippe s, but there are some prime timepieces from the likes of role x, Panerai and Cartier as well. Leading things off price wise is an exceptional platinum minute repeating perpetual calendar tourbillon Patel with retrograde date, phases of the moon and a black dial, est. $700,000 - $900,000.

From there prices drop dramatically and there are some deals to be found. We’re particularly fond of this 1945 steel Patek chronograph with register and tachometer, est. only $50,000 - $80,000. On the Rolex front there’s a rare 1972 stainless steel Submariner made for the British Royal Navy, est. $50,000 - $70,000, and a stainless 1983 Dayton a seismographer, est. $28,000 - $36,000. Also worth noting: an oversizes Panerai limited edition white gold dual time zone Radioman’s, est. $11,000 - $17,000. See the gallery for pix.
