It’s complicated …. With a total of 19 complications, the 1904 Dent Ultra Complication is one of the most complicated watches ever made. It has just five fewer functions than the Henry Graves Supercomplication - the most complicated watch ever made without the aid of computer technology – commissioned from Patek Philippe 20 years later. - This large and heavy watch is the product of a unique collaboration between the English firm Dent, the Swiss company Capt & Cie. of Solliat and the watchmaker Leon Aubert of Le Brassus. The latter two were tasked with producing the various complications, including a number of astronomical indications, such as the signs of the Zodiac, times of sunrise, sunset, moonrise and moonset, and moon phases with apparition of the Great Bear at the black moon. - The watch leads a group of fascinating antique double-dialled watches in our “Masterworks of Time” sale, open for bidding until 16 June. - #SothebysWatches #MasterworksofTime #DentWatch #supercomplication...
