In terms of size, types and artistic execution, this is one of the richest collections of domestic clocks in the Czech Republic. Apart from a torso of a Late Gothic interior clock, there are mostly signed Renaissance tabernacle or horizontal style metal table clocks, and Baroque table and longcase clocks, which were originally also part of interiors. Sculptural bronze French and Viennese clocks, and wooden, richly carved and gilt Czech and Moravian clocks are typical for the period of Classicism.

From the 19th century date Empire portico clocks and Biedermeier clocks often with added musical mechanism. Around mid 19th century framed wall and picture clocks appeared, followed by various types of clocks in historical, and later in Art Nouveau, styles. A metal table clock after a design by Josef Gočár is a rare example of a clock in Cubist style.

A precious collection of table sundials, a substantial collection of astronomical and other measuring instruments from the Rudolf II era (signed pieces by Erasmus Habermel among them) are also part of the horological collections.
