An impressive long case clock with brass composite dial signed "Anthony Janszen / Amsterdam." It is very unusual to find a tall case clock from this period that is signed, numbered, and dated by the clockmaker. This example is. 213005.


The time, strike, and alarm movement is brass, has an eight-day duration, and is 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 an alarm on a bell. The alarm is set 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 Maker's initials "A. J." and is dated and numbered "1766 / N.89." Janszen is a listed Maker. This date aligns with the clock's form 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 presents an excellent mellow tone that enhances the appearance of the burl wood grain. This long case is nicely proportioned and features several interesting construction details typically found on clocks made in Amsterdam during this period of clockmaking. The case proudly stands on four-turned and ebonized feet. They are applied to the bottom of the base and moldings. The base incorporates bold moldings in its design, which is three-dimensionally formed. The corners are nicely built out and add a decorative aspect to the form. This construction is sometimes called a mock bombe'. This detail transitions nicely into the waist section.

The waist of this case is long and narrow. The corners canted, getting their cue from the base panel. This detail accentuates the narrow proportions of this pleasing form. A large waist door is fitted into the center of this section. It is designed with an interesting shape at the top and bottom of the panel. The outer edge is nicely trimmed with an applied half-round molding. The top of the door is fitted with an applied carved detail. The center of this door is cut open and fitted with glass. Through this window, one can see the brass-covered pendulum bob. 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 a bull. Her outstretched hand is holding a wreath. This frame is heavily cast and of good quality.

The fanciful, arched molding found at the top of the bonnet is nicely formed. The blind frets are wonderfully executed and are backed in a sand-colored silk cloth. This detail allows the sound of the bells to resonate more easily from the inside of the case when the clock is striking. The bonnet door is arched at the top and is fitted with clear glass. Turned smooth bonnet columns terminate in brass capitals. These are applied to the bonnet door. The applied caddy top and the three-period figural finials are surmounting this case. The center one depicts Atlas. He is supporting the Universe on his shoulders.

The brass composite dial is skillfully engraved and features applied brass rococo spandrels, a silvered chapter ring that displays the hours and minutes, subsidiary seconds dial and a day of the week calendar and the Zodiac sign associated with it, a lunar calendar or an engraved moon phase mechanism is positioned in the arch, note the delicate engraving in the arch surrounding this feature and an engraved center mat.
