Cartier yellow gold open-faced pocket watch

Partially verified

This open-faced pocket watch by Cartier is dated by the auction house to circa 1930. The timepiece is housed in an 18k yellow gold cushion-shaped case measuring 43 mm, with the catalog noting that the case back is secured by four screws. The silvered dial is signed Cartier and Paris, featuring bold black Roman numeral hour markers, an inner railway minute track, and blued steel Breguet-style hands. At the top of the case, a distinct triangular pendant bow surmounts the winding crown. Sotheby's reports the watch is fitted with an 18-jewel manual-winding movement.
