There are not many documents about Schatz, everything
destroyed after the bankruptcy around 1983.
August Schatz in Triberg built from 1958 the large mechanical
clockwork (left) until around 1978, when this
clockwork was discontinued and replaced by the small
clockwork 39 which had been developed around 1960/65 for
the Miniaturschiffsglasenuhr (illustrated in Firmenchronik 1881-1981) and Midi. At the end of the 1970s, the Royal housing was changed so the small clockwork 39 could be fitted. The first battery-powered clock was developed in1956. It used a 4,5V battery. But already in 1958 the first 1,5V battery-powered clockwork was launched.
From then, many different battery-powered clockworks were
launched in different series through the 60s and 70s and it was
as late as 1980 the first battery-powered ship’s bell clockwork
was introduced (Schiffsquarzwerk mit Glasenschlag, also illustrated in the Firmenchronik 1881-1981).
