Dear friends, I am a collector of chess clocks and I own a PHS of which I frankly do not find much history. If anyone has information on the brand I would love to be able to exchange information. Greetings
Philipp Haas & Söhne ("PHS") was the maker of your clock movements.
The hare trademark was first used by Haas circa 1883, and Haas ceased business in 1930.
Haas movements are difficult to date as Haas did not leave many clues. Your movements were most likely made post 1900.
Haas, like most German movement makers, sold "loose" movements to the trade. The maker of your cabinet most likely purchased loose movements from Haas and cased them. It is possible, however, that someone has a Haas catalog with your chess clock and if so, we can narrow the date of manufacture.
I'm not sure exactly what information you are looking for, but as for the maker of the movement, here are some details.
The logo on the back plate, together with the nicely preserved label, tell us that the movement of your clock was manufactured by Philipp Haas & Söhne, in St. Georgen, Germany. The company was founded in 1867 and went out of business in 1935.
It is not easy to judge a date for your clock, but I would guess around 1890-1910.
