Time to watch shares his initial impressions of the Patek Philippe Ref. 5170P, focusing on the captivating way its dial transforms under varying light conditions. His observations highlight a key aspect of watch appreciation often overlooked in static photography: the dynamic interplay of light and material that brings a timepiece to life on the wrist. This exploration offers valuable insights for collectors considering this reference.






The Chronograph reference 5170, introduced in 2010, marked a significant development for Patek Philippe as it was the first serially produced chronograph to feature a fully in-house manufactured movement. This reference succeeded the reference 5070, transitioning from a Lemania-based caliber to a proprietary design, underscoring the brand's commitment to integrated manufacturing for its complications. It represents a modern interpretation of a classic chronograph layout within the Patek Philippe catalog.
The reference 5170 features a case measuring 39.4 mm in diameter and 10.9 mm in thickness, available in 18k white, rose, or yellow gold. It is equipped with the manual-winding caliber CH 29-535 PS, which offers a power reserve of 65 hours. The watch is fitted with a sapphire crystal and is water-resistant to 30 meters. The movement is visible through a sapphire case back, showcasing its intricate finishing.
This reference appeals to collectors seeking a contemporary Patek Philippe chronograph with an in-house movement. Early variants, such as the yellow gold reference 5170J-001, featured a pulsometer scale, which was later replaced by a minute track on subsequent iterations. The various metal options and dial configurations provide distinct aesthetic choices for collectors, reflecting different periods of its production run.
Viewing this piece at one location and at one time won’t give you a full understanding of the dial. Living with the watch daily it’s easier to see the different ways the dial changes under different lighting conditions. Sincerely H.
I’m learning fast that this is the case . Magic indeed! Sincerely H.
Try it with a blue glossy strap. The effect will be even more impressive
I do plan to change the strap at some point in the future and your suggestion of a glossy blue strap sounds right! But for now the black strap complements the elegant nature of the watch in my humble opinion. Sincerely H.
