Design
The case, made entirely of brass, has a broad, gently curved top. The black front, decorated with fine gold-coloured lines, frames a light-coloured, rounded-square dial. Gold-coloured hands and hour markers echo the finish of the case. Two slender, crossing feet give the clock a light, almost floating appearance.
Technology
Inside is a mechanical movement with a double ding-dong striking mechanism that sounds on the half-hour and hour. The brass case was cleaned, and the movement was dismantled, cleaned and professionally lubricated.

The ZentRa clock and watch brand originated in 1924, when Willi König and Willibald Felsing, associated with the Central Association of German Watchmakers, founded Markenuhr GmbH. The name Centra was initially used; it later became the distinctive spelling ZentRa, with its prominent capital R. On 4 September 1927, the Markenuhren-Verein was established in Berlin, together with its guarantee association.
ZentRa aimed to supply German specialist retailers with high-quality yet reasonably priced timepieces. A technical committee examined movements from various manufacturers before approving them for the brand. This commitment to quality was also reflected in the familiar advertising slogan “ZentRa – Die Uhr mit dem Reifezeugnis” (“ZentRa – the clock with a certificate of excellence”).
Over the following decades, ZentRa became one of Germany's leading specialist retail brands. At times, the association had more than 2,500 watchmakers and specialist dealers. Its range included wristwatches as well as wall, table and mantel clocks. Movements, and sometimes complete timepieces, came from various German and Swiss manufacturers and were sold under the ZentRa name.
After the Second World War, the Markenuhren-Verein became ZentRa-Markenuhren GmbH, based in Cologne. The brand was especially widespread among German specialist retailers from the 1950s to the 1970s. Quartz and digital timepieces later joined its traditional mechanical range.
Increasing international competition and changing distribution channels placed the brand under pressure. After several changes of ownership, RS-Uhrenhandelsgesellschaft mbH acquired the trademark licence in 2001. Since September 2020, the trademark rights have belonged to Zeitgeber GmbH in Hamburg. Mechanical watches are once again offered under the ZentRa name, continuing the brand's long tradition.
