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 page 14, find link below) 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 on page 16).

Schatz went bankrupt in 1982 and taken over by Staiger which was a very experienced clock manufacturer. They were the first to develop a quartz controlled movement for clocks and bring it onto the market. However Staiger continued to build the little mechanical clockwork 39 until 1993, when it was discontinued and replaced by the Hermle mechanical clockwork. Today Hermle and Chelsea Clocks are the only mechanical ship’s bell clockwork manufacturers on the world market. Our current electric ship’s bell clockwork was developed by Staiger at the subsidiary UTS in Haardt around 1985.
In 2025 we decided to discontinue our production of mechanical clocks driven by Hermle clockworks.
