Reference 5100 is Patek Philippe's first model featuring a ten-day power reserve. Made in a limited edition, this watch can never be recreated exactly as the firm destroyed the tools that were necessary for making the reference. The prestigious Geneva maker made a total of 3,000 pieces of reference 5100.
