BMR shares a new strap combination for their Patek Philippe Ref. 5170, highlighting its versatility and charm. This post delves into how a simple strap change can transform a classic chronograph, sparking a discussion about personal preferences and the enduring appeal of this Patek Philippe 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.
I’m a big fan of the blue.
It makes it more playful, which I rather like.
