Patek Philippe Grandmaster Chime in Steel for Only Watch 2019

The Grandmaster Chime Ref. 6300A was first rumoured in Baselworld earlier this year and in the same vein as recent Patek Philippe Only Watch editions, the Triple Complication Ref. 5208T-010 and the Minute Repeater Perpetual Calendar ref. 5016, was expected either in titanium or steel.

Celebrating Patek Philippe’s 175th anniversary in grand style in 2014, the Geneva manufacture created the limited edition Patek Philippe Grandmaster Chime in seven gold limited editions, and it became an emblem of the brand’s historical and modern achievements. Equipped with 20 different complications and information indicated on the Grandmaster Chime’s front and rear dials, depicting the pinnacle of maison.

A less ornate Grandmaster Chime in white gold was introduced in 2016 with the reference 6300G. In essence, it was the most complicated Patek Philippe wristwatch with the signature Geneva manufacture’s understated elegance boasting a front and back blue opaline dial with a hand-guilloched hobnail case eschewing filigree and engraving. For Only Watch 2019, Patek Philippe indulges us with another edition of the 5175, this time, a stainless steel edition of the Grandmaster Chime with a salmon dial on the front and a black dial on the back.


The 47.7mm steel Grandmaster Chime for Only Watch 2019 will be auctioned to provide funds for research on Duchenne muscular dystrophy this November and as usual, took media attention as THE watch to watch for Only Watch. The 20 complication Patek Philippe Grandmaster Chime debuted in 2014 as the reference 5175R and the Only Watch edition is available in a single, unique steel model, estimated to fetch bids of up to US$2.5 million.


The 20 complications include five chiming modes, two of which are patented world firsts: an acoustic alarm that strikes the preselected time and a date repeater sounding the date on demand. a steel case and a print that reads “The Only One” within the 12 o’clock subdial.

The Grandmaster Chime Ref. 6300A was first rumoured in Baselworld earlier this year and in the same vein as other Patek Philippe Only Watch editions, the Triple Complication Ref. 5208T-010 and the Minute Repeater Perpetual Calendar ref. 5016, was expected either in titanium or steel.
