The Cartier Magnum Tank from 1964 (estimate €200,000 – 400,000) is likely one of the rarest Cartier watches you will ever see, and but it will most definitely go for a lot lower than a record-breaking London Crash. Not like the « exceedingly uncommon » Audemars Piguet calendars retailed by Cartier, that is even rarer: a watch manufactured by Cartier France with an AP motion. Every dial on these Tanks was made in a singular configuration as nicely. In the meantime, Lot 108, an outsized Patek ref. 530 in metal with black dial and gold Breguet numerals comes from John Goldberger’s assortment. That is arguably the rarest and most essential Calatrava reference, and but, as Ben pointed out in 2017, scholarship has solely within the final 15-20 years even actually acknowledged them. Related watches have a assorted previous at public sale, from CHF 415,500 to CHF 1,445,000 between 2016 and 2017, however the estimate right here is €250,000 – 500,000.
