Record status
Individual type · partial
Period
Circa 1925
This exceptional manual-winding pocket watch, manufactured by Cartier and the European Watch & Clock Co. around 1925, is an important horological piece associated with the historic Locarno Treaties.
The timepiece features an 18K yellow gold case measuring 45.5 mm in diameter, characterized by a sophisticated aesthetic that combines metallic gold with striking black lacquer accents. The bow and band are further embellished with black diamonds, adding a luxurious contrast to the polished gold construction. The dial, signed by Cartier, displays classic Roman numeral indices and elegant hands. Beyond its functional role as a timepiece powered by an 18-jewel movement, the case bears a significant historical engraving featuring the signature of Aristide Briand and the date October 15, 1925, referencing the diplomatic negotiations held in Switzerland.
