A Posingis from the early 1930s! Paul Posingis was a watchmaker by profession and a passionate chess player. In 1927 he co-founded the chess club Werries (near Hamm / North Rhine-Westphalia) and soon began manufacturing chess clocks in his own workshop. This model must come from this early phase: 'silvered' clock face with a chess club logo on it cannot be mixed with something else! Photo: Max Bluemich vs. Alexander Alekhine (Krakow, 1941).

An ultra-rare Posingis edition, designed and manufactured in a very limited amount for the unofficial chess olympic games in Munich. A truly unique piece with a lovely design and a 4-hours dial. Masterpiece role belongs to the semi-common movement, which represents not just a conventional approach (duplicated mechanisms for each clock), but also incorporates some common parts (just one balance wheel per clock!).

Clock movements with a very characteristic 'bell' shapes have been produced by the company 'Gebr. Hauser' in Weigheim, Germany (founded in 1923 and discontinued its operations in 1964). These clock movement became a basis for the Paul Posingis clock series.

This model called a 'Standart' and could be recognised from the game between Svetozar Gligoric and Herman Steiner while Gregor Piatigorsky (r) and Mrs. Philip C. McKenna observe (Hollywood, 1952).

Another 'Standart' model, with a slightly different 'propeller-style' second hand as well as a slightly smaller depth of the wooden case. Otherwise pretty the same chess clock. Photo: a match Luxembourg vs. Island (1962).

Posingis 'Lux' model, which implies several improvements in comparison to the 'Standard' one: clock posesses a massive seesaw with steel buttons, being mounted at a slight angle on a wooden base. Numerous open sources state that the Posingis Lux originates from +/-1935, however I would rather challenge this fact: there are no photo evidences (games or Ads) from that period, furthermore, all proven earlier / 1930s models produced with metal clock faces (having a Werries/Hamm logo on it) and completely different movements. I would classify Lux as of 1940s (earliest), however may be someone knows more? Photo: Georges Philippe vs. Miguel Farre Mallofre (1959).

One more Posingis, however this time with a different movement (i believe with a Kaiser one).
