In a perennial debate among haute horology enthusiasts, afaleh presents a compelling visual comparison between two titans: the A. Lange & Söhne Datograph (first generation) and the Patek Philippe Ref. 5170P. This article delves into afaleh's detailed photographic essay, which meticulously showcases the finishing of both movements, inviting the WatchProSite community to weigh in on the nuances of craftsmanship from these esteemed manufacturers. His work provides a valuable resource for collectors seeking to understand the subtle distinctions that define top-tier watchmaking.


Yes, makes sense why great craftspeople are starting / joining 'smaller' independents. It truly does bring joy that impressively talented parts and watchmakers are now able to produce the quality they know is possible beyond typical 'corporate standards'. Kari's upcoming releases should be crazy great I bet!
Keep in mind, Lange movement parts are made of German Silver which is a material where a higher polish is able to be achieved, compared to the rhodium plated brass movement parts that Geneve style manufacturers use. Thus, a comparison between the two isn't entirely fair, as German Silver will generally "look better" to most eyes. It's not necessarily indicative that the team at Patek Philippe has less skill or spends less time on the equivalent polish process of that specific part.
The thickness gives a special rigidity among other things. Finishing ultra-thin movement parts is exceptionally difficult, as the parts are so thin that you don't want to damage them or distort them while finishing them. Neither of these are ultra-thin movements, but thickness still plays a part.
But a fairer comparison would probably be 5170 vs 2nd Gen 1815 chrono. Introduced around the same time and same level of complications.
Vacheron is currently better it appears in an apples to apples comparison. Lange is of course a wonderful "orange."
Also, I don’t understand why Patek puts a cap on the column wheel. It’s one of the most fascinating parts of the movement. Why cover it? The cap looks like something unappealing is being hidden and there’s nothing attractive or interesting about it.
