About the watch

This is the first and only Grandmaster Chime in steel – a very rare metal in the Genevan manufacture’s collection and particularly uncommon for a grand complication.

Launched in 2014 on the occasion of the company’s 175th anniversary, the Grandmaster Chime became part of the manufacture’s regular collection in a white-gold version in 2016.

The most complex Patek Philippe wristwatch features 20 complications, including five acoustic functions, two of which are patented global premières: an alarm that strikes the preprogrammed alarm time and a date repeater that sounds the date on demand. The double-face case with the guilloched hobnail pattern is endowed with a patented reversing mechanism.
