A rare Dutch walnut hooded wall clock by Jacob Hasius, circa 1725.
The 23-cm square brass dial has an applied silvered engraved chapter ring with Roman numerals which is signed J. Hasius Amsterdam. The shaped and pierced hands are made of blued steel and the alarm disc of silvered engraved brass. In the corners are cast brass mask spandrels. In the matted centre is a date aperture with foliate engraved surround.
The plated movement is driven by a weight with endless rope suspension and needs to be pulled up once a day. It is regulated by verge escapement in combination with short fixed pendulum. The clock has half hour striking by means of a countwheel on a bell. There is also an alarm which also strikes on this bell.
The walnut case is surmounted by three brass finials. The hood has fine moulding and glass panels on the front and sides.
