[b]patek philippe Grandmaster Chime 175th anniversary[/b]
To commemorate its 175th anniversary (released in 2014), Patek Philippe launched the Grandmaster Chime Ref. 5175R-001. At the time, it was the brand's most complicated timepiece, limited to only 7 pieces (6 sold to discerning collectors, 1 acquired by the Patek Philippe Museum). It embodied over 100,000 hours of research and development, boasting 20 complications and 6 technical patents, including two world firsts: a striking alarm and a date chime.
Background and Positioning
Founded in 1839, Patek Philippe celebrated its 175th anniversary in 2014. Ref. 5175R is the pinnacle of the commemorative collection and the brand's first reversible watch with a reversible mechanism integrated into the lugs, paying tribute to 175 years of watchmaking heritage with top-tier complications.
