Phillips in Association with Bacs & Russo is the watch department of the Phillips auction house, dedicated exclusively to the world’s finest collectors’ watches. Launched in November 2014 by Aurel Bacs and his partner, Livia Russo, the department was established in response to the ever- increasing need for today’s collectors to easily access scholarship, guidance, and quality across the board. The team of specialists is dedicated to an uncompromised approach to quality, transparency, and client service, and as a result, in its inaugural year, in just two auction seasons and locations, realized a total of $80.3 million. With ten watches selling for over $1 million, multiple world records including for any stainless steel watch and the most expensive wristwatch ever sold at auction, Phillips became the market leader in its two selling locations – Geneva and Hong Kong – in 2015.

As of May 2016, again with just two selling locations, Phillips achieved nearly $53 million in its Spring 2016 auction season, making it the undisputed worldwide market leader above all other auction houses. A selection of our recent record-breaking prices:
