Description: Koopman Chess Clock 1936
It is a large Dutch chess clock, manufactured in 1936. The design of the wooden case was used by the manufacturer Koopman in the early years of the 20th century.
it uses German-made alarm clocks.
The activation of this chess clock is through “Vertical top buttons” located on both sides of the clock, a button for each player. Each button stops the clock and activates the opposite clock. The internal mechanism, which joins both buttons, is the mechanism initially used by the chess clocks of this manufacturer. In 1937, he changed the system and maintained it until the 1990s.
In the chess clock collection, we have another Koopman chess clock 1914 very similar, which differs in the assembly of different clocks. There is a difference of 30 years between the two clocks. From an aesthetic point of view, the wood is similar, but this one has a greater weight, … perhaps only by the use of different woods in the box.
Another interesting detail on the clock, is an inscription on the back cover, ‘BOOGAARD’ Hilversum. It seems to be the name of the former owner and the Dutch city of Hilversum.
Finally, it is worth mentioning that the dials that are not used have been covered with a label, which symbolizes a chess board. Another detail coinciding with the Koopman chess clock 1914.
