The 5204R was first seen in October 2021, and showcases a new contemporary spirit. The Grand Complication collection from Patek Philippe showcases the superb artistry and skill of the true masters of horological complications. Since 1839 Patek Philippe have focused on showcasing the most complicated wristwatches, which embody an individual and distinguished elegance. First seen in the Patek Philippe collections in 1925 the perpetual calendar is one of the most famous and useful grand complications. This incredible feat of horological skill states the day, month, date, leap year, and moon phases automatically without needing any manual adjustment until 2100. The 5204R combines this exceptional complication with a split seconds chronograph with an instantaneous 30-minute counter. The split seconds complication enables different events that begin but do not end together to be timed. First seen in 2012 this exciting new rose gold model houses the manually wound mechanical movement (calibre CHR 29-535 PS Q), which has a maximum power reserve of 65 hours. A 40.00mm hand polished rose gold case combined with slate gray sunburst dial has an elegant presence on the wrist with a shiny gray calfskin embossed Alligator pattern strap providing the perfect finishing touch.
