A rare pair cased Swiss verge pocket watch with alarm, circa 1720.
The outer case is silver and engraved. Inner case is silver, rear bell. A white enamel dial, fine full plate movement, keywind, chain/fusee, one hammer, three-arm brass balance. The outer case of this pocket watch by Louis Nicolas Prevost is decorated with a simple but fine geometrical pattern. The inner case is equally lovingly finished. The scroll ornaments are open-worked for a better alarm signal. There is also a cartouche with an engraved view of a town. The watch has a lavishly decorated balance staff and an unusual engraved gold barrel for the alarm—a watch of high quality.
