Back in March 2010 Antiquorum auctioned one of the greatest vintage Patek Philippe wristwatches to appear on the market in recent years. It might not have the famous Graves coat of arms but the watch, originally purchased by a well-known New York businessman and inventor from Cartier in 1950, was unique; eventually selling to a private collector for US$710,000.
It featured a previously unknown movement used by Patek Philippe in their minute repeating wristwatches, an oversized crown, subsidiary seconds and repeater slide. The gold indexes had been painted black when the owner reached old age to assist in visibility. Probably considered ugly and unrefined due to its enlarged aspects back in the 1950s, today it is just beautiful. Full details from the auction catalog can be found below.
Offered in exceptional overall condition, below are images taken of the movement and under-dial view while partially disassembled that didn't make it into the catalog.
