Period
circa 1725
This coach clock, measuring 61 mm in diameter and weighing 227 g, is dated circa 1725 with origins reported in Germany. The auction house attributes the piece presumably to Augsburg Baroque watchmaker Johann Jakob Haase, noting it was previously held in the Fraenkel Collection under inventory number 49.
The piece features a silver case with an open-worked rim engraved with hunting dogs and acanthus tendrils, housing a rear bell. Its silver champlevé dial displays Roman hour markers, an outer five-minute track with Arabic numerals, and a central engraved cartouche signed 'HASE'. According to the catalogue, it is driven by a chain-and-fusee full plate movement with a florally engraved barrel, locking plate hour strike mechanism, single hammer, and a three-arm brass balance.
