The 44mm case houses a dial plate finished with a traditional hand-frosted texture, a signature aesthetic of the Legacy Machine collection. Collectors value this specific reference for its lightweight construction and the technical complexity of the split escapement architecture. On the secondary market, these timepieces typically trade in the low-to-mid six-figure range, often between $110,000 and $140,000 depending on condition.
