The Collection comprises table clocks with pendulum, made in France mainly during the first half of the nineteenth century and decorated with subjects from works by philhellene artists, as well as mantel clocks produced in France during the second half of the nineteenth century, which come from the palaces of King George I.

There are also pocket watches of English, French and Swiss manufacture, of the eighteenth, nineteenth and twentieth centuries, most of which belonged to freedom fighters of 1821, politicians and military men of Modern Greece.

The first eponymous timepiece in the Collection entered the Museum in 1897 and is the pocket watch of Theodoros Kolokotronis.

Unique in the Collection are the four pairs of hands from the remnants of the clock that was installed in the Agora tower, which was known also as “Elgin’s clock-tower”. These hands came into the possession of the Historical and Ethnological Society of Greece in 1898.
