Antique open face silver pocket watch by D.D. Neveren (London), with a white dial and roman numerals. The watch has British hallmarks, the assay mark for London before 1822 (Crowned leopard head), the sovereign's head, a makers mark and a year letter. The manual movement has a verge fusee. A verge fusee is a type of mechanical timekeeping mechanism that was commonly used in early clockmaking and watchmaking, particularly in the 17th and 18th centuries. The mechanism consists of two main components: the verge escapement and the fusee. Verge Escapement: This is one of the earliest types of escapements used in clocks and watches. The verge is a pivoted lever that oscillates back and forth, allowing the gear train to advance at a controlled rate. The motion of the verge escapement is regulated by a pendulum or a balance wheel. Fusee: The fusee is a conical-shaped pulley that is designed to compensate for the varying tension of the main spring as it unwinds. As the spring winds down, the fusee allows the movement to maintain a consistent force on the gear train, improving timekeeping accuracy. Together, the verge escapement and fusee create a reliable mechanism for timekeeping. The watch comes with the original watch winding key, a watch chain and a silver pair case. - 47 mm, with pair case 56 mm, watch chain 36 cm. -
