Patek Philippe Complications 5905

Patek Philippe Complications 5905/1A-001 is a chronograph in steel, measuring 42 mm across and 14.13 mm thick. The case houses the self-winding calibre CH 28-520 QA 24H, a flyback chronograph movement with a 45-hour power reserve, and its sapphire crystal caseback lets the mechanism show through. The sunburst green dial carries an annual calendar with day, date and month, requiring only one correction a year. Faceted white gold hands with luminous coating sit alongside applied hour markers for legibility. Flyback function and a 60-minute counter round out the chronograph work. The integrated steel bracelet closes with a fold-over clasp finished in polished and satin steel. Water resistance tops out at 30 metres.
