The instruments for measuring time in this collection are from a technical and chronological perspective divided into elementary chronometric instruments, mechanical clocks, electromechanical clocks and electric clocks. The group of elementary chronometric instruments includes sundials (only a few specimens; the others are in the collection of  (astronomical instruments), water, candle and sand clocks. The most extensive part of the collection consists of mechanical clocks.

The group of elementary chronometric instruments includes sundials (only a few specimens; the others are in the collection of  (astronomical instruments), water, candle and sand clocks. The most extensive part of the collection consists of mechanical clocks. The collection also features a relatively extensive set of tower clocks of various constructions, age and places of origin. Interior table, wall and floor clocks span the period from the late 16th century to present. This group also includes “mysterious clocks”, music box clocks and a group of clocks from Black Forest (Schwarzwald) village clockmakers. The collection of pocket and wrist watches is also extensive. The mechanical clocks include a collection of different timers and professional and special clocks. In addition to the mechanical clocks themselves, there is also a set of models of clocks manufactured by leading Czech mechanic and inventor of the 19th century Josef Božek. and showing their development. A separate chapter consists of clocks that were constructed using electrical principles in combination with a mechanical oscillator, as they’ve been built since the end of the 20th century. The collection’s last group consists of electronic clocks in which the mechanical element was fully or partially eliminated and which achieve greater accuracy.
