Artist Niklas Roy has presented the Glashütte Trash Clock, a mechanical clock assembled from trash and other materials found in Glashütte, Saxony. It runs for about 30 minutes, shows seconds and minutes, strikes a gong at the top of each minute and triggers an external randomizer shortly before its stored energy runs out.
Artist Niklas Roy has presented a mechanical timepiece built from trash and other materials found in Glashütte, Saxony. The Glashütte Trash Clock runs for about 30 minutes, displaying seconds and minutes, sounding a gong at each minute’s 12 o’clock position and activating an external randomizer shortly before it runs out of energy.
Roy describes the project on his website as a functioning clockwork mechanism made during a 2026 artist residency in Glashütte. Its short operating time means it does not show hours. The clock instead focuses on seconds and minutes, with the gong marking each completed minute while the mechanism is running. Roy also built in a separate randomizer trigger near the end of the clock’s stored energy.
The build draws on familiar mechanical-clock principles, adapted to materials available to Roy. In the account, he describes experimenting with a pendulum and making an escapement using a bent metal rod and paperclips as gear teeth. An escapement controls the release of energy to the pendulum while advancing the clock’s mechanism. Roy says making the parts work reliably from discarded materials was a challenge because they needed to be sufficiently sturdy and precise.
Roy also says he devised a time scale called GTC, combining concepts from GMT and UTC, and casts the clock as its global reference. That framing is part of the project’s presentation; the supplied account does not describe GTC as an adopted or recognized civil time standard.
A Clock Built Around Reuse
The project makes the construction of a mechanical clock visible: a pendulum, escapement, energy source and indicators must work together for the mechanism to keep time. Roy’s use of found objects, including paperclips, shows how ordinary materials can be adapted to those functions, while the clock’s limited runtime makes the design’s constraints part of the finished work.
Its relevance is also tied to place. Glashütte is internationally associated with watchmaking, and Roy made the clock there during a residency hosted by NOMOS, according to his account. The contrast between that setting and a mechanism assembled from trash gives the project a clear local and artistic premise. The available material does not provide independent timing tests or a comparison with commercial clocks, so its significance is best understood as an art-and-making project rather than a claim about clockmaking performance.

From Watchmaking Heritage to Found Materials
Roy links the project to his family history: he says his great-great-grandfather Henri Roy and great-grandfather Eduard Roy were Swiss watchmakers who later moved to Herrnhut, in Saxony, where they continued making clocks and watches. In 2026, Roy says, NOMOS invited him to an artist residency in Glashütte, giving him the chance to make a clock while working in a town known for mechanical timepieces.
His website describes starting with a pendulum experiment, using a plastic water bottle as the bob and a folding wooden ruler as the rod. He then consulted a vintage watchmaking textbook and adapted established mechanical ideas to available materials. The account explains that a pendulum’s timing depends on its length and local gravity, and describes the escapement as both regulating the wheel’s advance and giving the pendulum a push. These details explain the mechanism without implying that the clock is designed for long-term timekeeping.
Runtime and GTC Status
The source describes the clock as running for about half an hour but gives no test conditions, measured accuracy or detailed performance data. It is not clear how consistently the mechanism keeps time across a full run, how frequently it needs adjustment or what materials and energy-storage components make up the complete build; the supplied report ends partway through its explanation of the energy system.
Roy describes GTC as a blend of GMT and UTC and calls the clock its global reference. No details are provided on a formal definition, participating users or adoption beyond the project. The source also does not give a precise date for the clock’s public presentation beyond identifying the project as a 2026 work.
Further Build Details to Watch
The project page is the main source for the clock’s construction and operation. Further documentation could clarify how the energy-storage mechanism works, how the randomizer is connected, and what materials were used for each component. Until those details or independent tests are available, the confirmed account is limited to Roy’s description of a clock that runs for about 30 minutes and performs the stated functions.
Key Questions
What is the Glashütte Trash Clock?
It is an artwork by Niklas Roy: a mechanical clock built from trash and other materials he found in Glashütte, Saxony.
How long does it run?
Roy says it runs for about half an hour. The source does not provide independent test results or a more exact measured runtime.
What does the clock display and do?
It displays seconds and minutes, strikes a gong when the minute hand reaches 12, and triggers an external randomizer shortly before its energy runs out.
Is GTC an official time zone or standard?
Roy describes GTC as a time scale blending concepts from GMT and UTC and names his clock as its reference. The source does not show that GTC has been formally adopted as a time standard.
Why was the clock made in Glashütte?
Roy says he made it during a 2026 artist residency hosted by NOMOS. He connects the location to Glashütte’s watchmaking reputation and to his own family history of clock and watchmakers.
