You can get a second-hand Saxonia for under £10k and it’s objectively a better watch than a PP Calatrava in every way. Although Patek is Patek, so it’ll always be “worth” more. Lange is not really a good investment.
My personal favourite AL&S are the most basic Saxonia (eg the ultra thin), the basic Lange 1 and Lange 1 time zone, and the 1815 chrono.
