Chess clocks are a creation of the 19th Century , when timing games via sandclocks was considered to be unpractical. The first chess clocks were made by watchmakers combining two mechanisms on a balance lever - fe Fattorini in London. Later standard designs came about that responded better to the needs of the game. The end of mechanical clocks is in sight, enforced by varied time rithms imposed by FIDE - in the near future, early digital timers will become collectors items as well.
King of Aires
And a really sweet one from Buenos Aires, the "King" clock - the most significant part of the entrails are the three massive lead slugs meant to stabilize this high and narrow clock ! In addition, we have an enlarged base! Chinese clockworks, with some plastic cogs in the middle. From when: the 70ies ?
A fairly rough postwar Roa, crudely cobbled together from two alarm clocks via a bottom frame and a top lever
Successor to the bakelite clock from Czechia, this attractive clock is a blatant copy of the GDR Garde without the quality. Dicey buton action, constant problems with the changeover bar for the clock stoppers - by this time the former Chronotechna had changed names and figured under the name Prim!
