It is hard to miss the recurring comments about the relative desirability and value of watches with in-house versus
purchased movements, there are so many aspects regarding exclusivity, prestige, beauty and "fitness", as well as

1960s Vacheron & Constantin Chronometre Royal Cal. P1008/BS. Built from a JLC 12.5 ligne ebauche, still one of

Roger Dubuis Condottieri Cal. RD27. Rebridged and refinished Cyma/Tavannes 15 ligne pocketwatch movement
circa 1940s, a fabulous effort!
Audemars Piguet Cal. VZSS, circa 1948. Started life as an example of one of the most popular movements of the
era, Valjoux 13 ligne, used prominently as the base for chronographs and complicated calendars, AP has
presented a breathtaking, simple version:
