We know of, or have heard of, 22 of them, most of which are in Museums: 1. British Museum: Schlottheims silver clock, ca 1605, and a gorgeous miniature Augsburg silver clock, ca 1600. 2. Kunsthistorisches Museum, Vienna: Bacchus silver chariot, ca 1605. A complicated silver Augsburg table clock, double silver gilt clock with agate and garnets case, and Atlas silver clock by Jerg Ernst. 3. Swiss National Museum, Zurich: Table clock with silver case by Thomas Proll, ca 1711. 4. Württembergisches Landes Museum, Stuttgart: Silver tower-form clock by JohannSayller of Ulm, ca 1630. 5. Dresdens Grünes Gewölbe has the so called Hubertus-Uhr, a silver clock, ca 1725, with monogram of August II the Strong. 6. Inprivate collections there, one silver clock by Johann Buschmann, 1660/70 in a Milwaukees private collection. Another one, also by Buchmann, in New York collection. Two silver clocks in an Italian collection, one in London. This clock is the forerunner of those few magnificent silver carriage clocks. It is the earliest known silver carriage clock made with alarm, striking and push repeat. With regard to the push repeat, it is important to note that in a regular hour repeating clock the error can be, of course, up to one hour. The construction of this clock is such that the error is only one half an hour. This was achieved by making two separate mechanisms to change the striking and the repeating. The striking advances with each hour, but the repeating advances at each half hour. For example, at 2:10 the clock will repeat twice but at 2:50 it will repeat three times, therefore, in bothexamples making the same error of 10 minutes only. Museum für Kunsthandwerk in Dresden had, before 1945, a similar carriage clock by the same maker, slightly later and, of course, not in a silver case. The shape and the details of the case, however, were almost identical with our clock (Klaus Maurice, Die deutsche Räderuhr, München 1976, Vol II, photo No. 1054).
