Artist Niklas Roy presented the Glashütte Trash Clock, a mechanical pendulum clock built from trash and other materials found in Glashütte, Saxony. The mechanism runs for about 30 minutes, shows seconds and minutes, and strikes a gong at each minute; the available source text does not describe all of its construction or establish its accuracy.
Artist Niklas Roy has made a functioning mechanical pendulum clock from trash and other materials found in Glashütte, Saxony. Called the Glashütte Trash Clock, it runs for about 30 minutes, displays seconds and minutes, and strikes a gong when the minute hand reaches 12, according to Roy’s project report.
Roy’s report describes the clock as a mechanism built during a 2026 artist residency in Glashütte. Its limited running time shapes what it can show: the clock has seconds and minutes, but the report does not describe an hour display. At the end of its stored energy, it also triggers an external randomizer, an additional feature Roy mentions without explaining its operation in the supplied text.
The account details Roy’s approach to the pendulum and escapement. He used a wooden folding ruler for an adjustable pendulum rod in early experiments and a plastic water bottle as a bob. For the clock’s escapement, he says he bent a metal rod into the anchor and used paperclips as wheel teeth. The escapement releases the wheel in steps and gives the pendulum a small push with each swing, helping sustain its motion.
Roy says a seconds pendulum paired with a 30-tooth escapement wheel can turn an indicator once per minute: each swing advances the wheel by half a tooth. The supplied source excerpt ends partway through its discussion of the clock’s energy system, so it does not establish which materials or design completed that part of the mechanism. Roy also introduces a time scale called GTC, described as blending GMT and UTC, with the clock as its reference. No technical definition or means of keeping that scale synchronized is included in the excerpt.
A Clock Built From Local Discards
The project puts a familiar precision object—a mechanical clock—in an unconventional materials setting. Glashütte is associated with watchmaking, while Roy says this clock was assembled from discarded and found objects, including paperclips. That contrast is part of the project’s premise, not evidence that the clock matches the accuracy or durability of commercial timepieces.
For readers interested in mechanics, Roy’s report makes the clock’s operating principle legible: the pendulum regulates the pace, while the escapement both counts its swings and supplies small impulses. The 30-minute run also makes clear that this is a limited-duration mechanism, rather than a conventional clock intended to keep time continuously. Its display and gong offer a working demonstration of the design within those limits.

Glashütte’s Watchmaking Setting
Roy says NOMOS, a mechanical wristwatch manufacturer, invited him to an artist residency in Glashütte in 2026. He connected the project to his family history: his great-great-grandfather Henri Roy and great-grandfather Eduard Roy were Swiss watchmakers who later moved to Herrnhut, Saxony. That history helps explain why he chose to build a clock during the residency, though the mechanism itself is Roy’s project.
Glashütte is known for mechanical timepieces. Roy’s report also notes that the designation “Glashütte/SA” is legally protected for clocks and watches that meet the relevant place-of-origin requirement. The project’s title refers to the town, but the report describes a clock made from found materials, not a commercial product or a watch bearing that designation on a dial.
Roy draws on a vintage clockmaking textbook, Mechanische Uhren, for his explanation of pendulum timing and escapements. He references the familiar relation between pendulum length and its period, while noting that the idealized formula does not perfectly describe a real swinging pendulum. This technical background frames the build as a practical attempt to adapt established clock mechanisms to materials at hand.
Accuracy and Power Details Unreported
The available source material does not state how accurately the clock keeps time, how its roughly 30-minute running duration was measured, or whether the mechanism can be wound and restarted repeatedly. It also does not include the remainder of Roy’s explanation of the energy-storage design, so the materials and mechanism that power the clock cannot be fully described here.
Details of the external randomizer are also absent from the supplied excerpt: its design, purpose, and relationship to the clock’s final moments are not specified. Roy introduces GTC as a time scale blending GMT and UTC, but does not explain how it differs from those standards or how the clock would serve as a reference beyond the project. The report does not establish whether the clock is on public display, available to build from plans, or intended for sale.
Further Build Details Would Clarify
The next useful information for readers would be the complete project account, particularly the section on the clock’s energy supply and the design of its randomizer. Roy’s report, as supplied, does not announce a follow-up build, exhibition schedule, release of construction plans, or commercial production. Until those details are published, the confirmed development is the documented creation of a working clock with a short run, not a broader product launch.
Readers seeking to assess the clock’s performance would need details such as timing tests, repeatability, and how the mechanism is started and powered. For now, Roy’s own report remains the source for its construction, operating duration, and claimed features.
Key Questions
What is the Glashütte Trash Clock?
It is a mechanical pendulum clock that Niklas Roy says he built from trash and other materials found in Glashütte, Germany. Roy describes it as a functioning clock mechanism.
How long does it run?
Roy says the clock runs for about half an hour. The supplied report does not explain how that duration was measured or whether it varies between runs.
What does the clock display?
It displays seconds and minutes, and Roy says it strikes a gong when the minute hand reaches 12. The report does not describe an hour display.
What materials did Roy use?
Roy identifies a bent metal rod for the escapement anchor and paperclips for the escapement-wheel teeth. In early pendulum experiments, he also used a wooden folding ruler for the rod and a plastic water bottle for the bob.
What is GTC?
Roy calls GTC a time scale that blends GMT and UTC, with the clock serving as its reference. The supplied account does not provide a technical definition or explain how GTC is synchronized.
