A Dutch pair-cased verge pocket watch of museum quality with date aperture, mock pendulum and outer repoussé case King Solomon and the Queen of Sheba, made by French case maker Jeremias Cochin, circa 1730.
Two cases: a silver repoussé outer case, depicting a classical scene King Solomon and the Queen of Sheba signed Cochin, with a large lateral hinge; and a silver polished inner case. Silver champlevé dial with inlaid radial Roman hours and Arabic minutes, a chased putto scene with signature Uyterweer in the centre, date aperture, gilt hands, and arcaded chapter ring. Fine full plate movement, keywind, applied decorations, fire gilt, signed, chain/fusee, baluster movement pillars, and ring balance with mock pendulum. The engraved silver balance bridge is particularly striking: it shows the personification of Africa with an engraved banner ‘T Land Africa. A glazed kidney-shaped opening reveals the balance as a mock pendulum.

Cornelis Uyterweerwas one of the most influential Dutch watchmakers of his time. He was a master craftsman and head of the guild in Rotterdam from 1749 until 1769. His timepieces are famed for their unusual balance bridges, often with mock pendulum, and for finely wrought Repoussé cases such as this.
