Paul Stübner Precision Pendulum Clock
Record status
Individual type · partial
Period
circa 1920
This astronomical precision seconds pendulum clock was manufactured by Paul Stübner, a Glashütte-based clockmaker who established his business in 1905. The timepiece features a rectangular-shaped brass movement driven by a weight and incorporates a Graham escapement with adjustable steel pallets featuring inlaid sapphires.
It is equipped with a lateral impulse pendulum spring suspension and an invar steel pendulum, identified as "type K" with number 2217 and DRP number 100870. The clock stands 1490 mm tall and is housed in a mahogany case with a silvered dial. According to the provided archive details, the mechanism was delivered to Stübner on January 5th, 1919, as documented in the Riefler catalogue of works under number 265. Stübner, formerly an employee of Strasser & Rohde, primarily utilized Riefler pendulums for his precision clocks throughout his career, which spanned from 1905 until his retirement in the 1930s.

Design
- Case and Dial
- The clock is housed in a tall, floor-standing mahogany case measuring 1490 mm. The design features a large glass panel in the lower section, which allows for the observation of the pendulum's motion, while the upper section contains the dial and the movement. The case is described by the auction description as being in very good condition with some surface scratching. The silvered dial is situated at the top of the clock, consistent with standard astronomical regulator layouts. According to the condition report, the dial remains in very good condition, although it shows signs of slight oxidation.
- Visible features
- • Mahogany wood case with full-length glass door • Silvered circular clock dial with indices • Weight-driven movement with cord suspension • Brass plates connected by cylindrical pillars
- Movement and Pendulum
- The clock is powered by a weight-driven, rectangular-shaped brass movement. The escapement is a Graham type, featuring adjustable steel pallets with inlaid sapphires. This configuration was designed to reduce friction and improve timekeeping accuracy. The movement is mounted to allow for the attachment of a precision pendulum, which is an invar steel "type K" model, bearing the number 2217 and DRP number 100870. The pendulum utilizes a lateral impulse pendulum spring suspension system. The auction house reports the movement is in very good condition but notes that it is to be restored.
- Provenance and Documentation
- The clock is accompanied by specific archival data relating to its components. The source notes that the movement, identified as number 265, was delivered to Paul Stübner on January 5th, 1919, according to the Riefler catalogue of works. Paul Stübner operated his own workshop in Glashütte starting in 1905, having previously worked for the firm Strasser & Rohde for 25 years. Throughout his production history, Stübner utilized Riefler pendulums for the majority of his clocks, with a transition to Strasser & Rohde pendulums observed in items produced around 1920. The object is officially classified as an astronomical Glashütte precision seconds pendulum clock. Stübner specialized in the production of precision pendulum clocks, a pursuit linked by the source to the Imperial Navy's requirements for independent marine chronometer supplies.
