For me the Classic Perpetual Ludwig is a wonderful exercise in nostalgia, and the more so for its continued use of a movement that debuted in 1996 and represents a now seldom-seen but once very common Swiss watchmaking practice, which was to obtain high grade movements from a third party supplier with real movement expertise, and adapt that movement to a specific purpose. Lemania as well as F. Piguet (now Manufacture Blancpain) as well as others famous for making watches in their own right, such as Jaeger-LeCoultre and Audemars Piguet, were critical to the industry for many years. The modern emphasis on in-house movements as a good in themselves, and exclusive of other considerations, is a relatively new perspective and while it’s led to the creation of some interesting movements and watches it has also created a much more expensive climate for both brands and consumers.
