The pocket watch saw the light of day thanks to the inventiveness and creative spirit of Jules Audemars, with the help of his associate Edward Piguet. In 1882 they founded the Audemars Piguet & Co. Foundation. The first pocket watch originated from this foundation. Rare vintage Ultra pocket watch from 1920 in very nice aesthetic condition. Silver case with hallmark, case diameter: 45 mm without the bow. Enamelled dial with blued steel Empire hands, small second hand at 6 o'clock. Hand-wound mechanical movement, it was serviced by a master watchmaker and functions perfectly. Weight 59 g. Will be carefully packaged and sent via registered post. Happy bidding to all.
