213005 An impressive long case clock with brass composite dial signed Anthony Janszen / Amsterdam. It is very unusual to find a tall case clock of this period that is signed, numbered and dated by the clockmaker. This example is.
The time, strike and alarm movement is brass, eight-day duration and of excellent quality. It features the traditional Dutch striking system. As a result, this clock strikes the hour on the hour on a large bell. On the half hour, it will strike the coming hour on a smaller bell. This movement also features an alarm mechanism that is mounted to the side of the movement. It is wound by pulling on a cord inside the case that raises a small weight. When set, it will strike or sound and alarm on a bell. The setting of the alarm is done from the front of the dial. An alarm disk is mounted around the hour pipe. While removing the hour pipe bridge, our repairman discovered that it was engraved with the Makers initials "A.J." and it is dated and numbered "1766 / N.89." Janszen is a listed Maker. This date falls in line with the form of the clock and his listed working dates.The case exhibits excellent burl walnut veneers that cover the entire oak substructure. The walnut has been refinished and now exhibits a wonderful mellow tone that enhances the appearance of the burl wood grain. This long case is nicely proportioned and features a number of interesting construction details that are typical found on clocks made in Amsterdam during this period of clockmaking. The case proudly stands on four turned feet that are finished with an ebonized finish. They are applied to the bottom of the base and moldings.

The outer edge is nicely trimmed with an applied half round molding. The top of the door id fitted with an applied carved detail.

One would be able to visually tell that the clock is operational if the bob is in motion. It also lets the viewer know that this clock is fitted with a long pendulum rod due to the distance of the bob from the dial. This window is framed with a brass decoration that features a rococo style framing. A maiden sits atop of a bull. Her outstretched hand is holding a wreath. This frame is heavily cast and good quality.
