This is a Cartier pocket watch manufactured in the 1920s, fitted with an EWC (European Watch & Clock Company) movement, and housed in an 18K yellow gold case with a multi-pattern guilloché dial.
The watch is powered by a superbly finished EWC-made movement with 19 jewels, adjusted to eight positions, displaying a level of craftsmanship that is truly striking.
The dial features a matte white base adorned with multiple distinct guilloché patterns. The outer chapter ring displays 12-hour Roman numerals, while the inner ring shows 24-hour Arabic numerals. The spade-style hands are designed to indicate both 12-hour and 24-hour time, resulting in a highly intricate and distinctive construction.
With its original design, exceptional detailing, and refined execution, this is an extremely rare and valuable piece that allows one to fully appreciate the unique aesthetic world that is unmistakably Cartier.
