In a compelling 'This or That' challenge, WatchProSite contributor chap presents a fascinating horological dilemma: the Patek Philippe 5170R versus the De Bethune DB8R. This post invites collectors to weigh in on two distinct philosophies of high watchmaking, prompting a rich discussion on aesthetics, technical prowess, and the allure of exclusivity. chap's detailed comparison highlights the nuances that define each reference, making this a valuable resource for understanding these exceptional chronographs.

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.
intemporal design, my favorite dressy chronoπ

The golden dial is classy. Itβs a chronograph which do not scream itβs a chronograph. Other DeBethune watches are very good designs, so this brand do a good job for me. Colleague Voutilainen the same.
classy ! Since this is a Patek forum and I am the co-moderator, the 5170 gets a bigger nod ! π
R vs R Opaline vs Radial Guilloche'd Rose Gold Dial Applied Breguet vs Blue Printed (but 3d somehow) Arabics Manual (better winding feel) vs Manual In house 4hz Patek chrono vs THA monopusher movement from a few wannabes (Journe / V Halter / Flaggiolet) Both column wheel, lateral clutch, oscillating pinion 39.4 x 10.9mm vs 42 x 9.4mm Similar leaf hands, one RG, one blued 30min jumping chrono, hacking seconds vs 45min jumping "futbol" chrono (no running seconds), both recessed subdials ~2.5yr now
