A fine Swiss 18 carat pink gold open faced quarter repeating pocket watch, circa 1820. It has a mechanical key winding fire gilded brass movement with a chain and fusee, a verge escapement, and an exceptionally large, ornately pierced, hand engraved skeletonized balance bridge with an endstone. The watch includes a vibrant blue enamel steel regulator disc and a quarter repeating mechanism that strikes two steel gongs when the top pendant is pressed. The movement plates are lavishly decorated with floral and scroll engraving.

The white enamel dial is faulty, showing damage and material loss near 2 and 3 o’clock. It features black Arabic numerals for the hours, a fine outer minute track, and blued steel Breguet style hands. The timepiece is housed in an 18 carat pink gold open faced case with a finely engine turned reverse back cover decorated with a small vacant shield cartouche at the base, a corded caseband edge, and a hinged front bezel with glass cover.
