Catalogue description
Catalogue description from University of Graz (German)
Die quadratische Tischuhr steht auf vier kugelförmigen Füßen und weist ein arabisches Ziffernblatt mit Stunden- und Minutenanzeige auf. Bei Betätigung des seitlich hervorstehenden Knopfes ertönt ein Klang. Die gesamte Oberfläche der Tischuhr wurde vergoldet und an der Außenseite ist ein Blütendekor angebracht, der sich aus Email und Edelsteinen zusammensetzt (Çakmut/Gürbüz, Topkapı, 40, 110; Davis, Clocks, 43). Diese Verzierung ahmt offensichtlich den osmanischen Dekorstil aus der Zeit Ahmeds III. nach, der z.B. auf einem Pferdebrustriemen aus der kaiserlichen Wagenburg in Wien zu finden ist (G 259).

Historical context
Early Modern Horology (1600 – 1750)
Huygens' pendulum and balance spring transform accuracy; English makers develop the anchor and deadbeat escapements.
Huygens's pendulum (1656–57) improved clock accuracy from about a quarter of an hour to under a minute a day. The anchor escapement (c. 1670) and the long seconds pendulum created the longcase clock; London makers such as Fromanteel, Knibb, Tompion and Quare led European clockmaking, and French makers created the Boulle pendule.

Atlas type guide
Bracket, table and spring-driven clocks
Spring-driven clocks freed timekeeping from the hanging weight. The coiled mainspring, documented from the fifteenth century, made portable table clocks possible; to even out its declining force, makers used the fusee, a conical pulley connected to the barrel by a gut line or chain. Renaissance table clocks from Augsburg and Nuremberg — drum-shaped, square or tower-shaped in gilt brass — were luxury scientific objects, often with astronomical dials and alarms.
After the pendulum, English makers developed the bracket clock: a wooden case with a carrying handle, a short pendulum with a verge escapement, and often repeating work to sound the hours on demand at night. Later examples use the anchor escapement. In the nineteenth century, 'table clock' became a broad term for spring clocks of every nationality.
What to look for
- A fusee in the movement (cone-shaped pulley) and the type of line — gut or chain.
- Verge escapement with a short bob pendulum, often with a decoratively engraved backplate.
- Repeat cords or buttons that make the clock strike again on demand.
- Gilt-brass engraved cases and horizontal dials on Renaissance pieces.
- Case shapes: inverted bell, bell top, break-arch, lancet or balloon.
Dating clues
- Drum and tower table clocks: c. 1520–1650.
- Ebony veneered English bracket clocks with verge escapements: c. 1670–1800.
- Engraved backplates were usual on English clocks until c. 1800, then generally plain.
