Captures movement that changes orientation, with or without translation.
Rotational course

What it is Filled
A movement is the internal mechanism of a pocket watch or wristwatch that keeps time and drives its time indication and any additional functions.
In scope
- Movement identity, design, provenance and compatibility with the watch are in scope.
- Power sources and mechanisms that sustain timekeeping are in scope.
- Time regulation, transmission and interfaces with the time display are in scope.
- Additional functions integrated into the movement are in scope.
- Evidence of condition, timekeeping performance and service history is in scope.
- Documentation of replacement parts and alterations is in scope.
Out of scope
- Physical motion as a general phenomenon is outside this model.
- Social, political and artistic movements are outside this model.
- A movement as a section of a musical composition is outside this model.
- Watch cases, straps and external styling are outside this model except where they affect movement compatibility or protection.
- Clock mechanisms outside pocket watches and wristwatches are outside this model.
- The complete watch's ownership and commercial lifecycle are outside this model except where they establish movement provenance.
Why it exists Filled
Enable an agent to identify a watch movement, assess evidence about its design, provenance and condition, and recognise when specialist assessment is required.
Distinguishing features Filled
- A watch movement is an internal timekeeping mechanism rather than an episode of physical motion.
- The movement is distinct from the case, dial and hands, although it interfaces with the watch's time display.
- Mechanical movements use a mainspring and regulating mechanism, while quartz movements use an electronic oscillator.
- Manual winding and automatic winding describe different ways of supplying energy to mechanical movements.
- Movement identity and originality require supporting evidence rather than inference from the watch's external branding alone.
What robots and AI may and may not do Filled
Must not
- Claim movement authenticity, originality or service condition without supporting evidence.
- Recommend interventions beyond the available evidence or the operator's competence.
- Misrepresent replacement parts or alterations as original components.
- Authorise work on a watch without the owner's permission.
Only with a human decision
- Physical servicing, repair or modification requires a competent human specialist.
- Authenticity or valuation decisions with material consequences require human review.
May
- Describe movement types and functions from reliable documentation.
- Compare documented movement markings and features with reference information.
- Summarise recorded condition, timekeeping performance and service history.
Moral aspects Filled
- Undocumented alterations can diminish historical integrity and mislead future owners.
- Owners deserve accurate disclosure of condition, replacement parts and uncertainty.
- Historically significant movements may warrant conservation expertise.
Who is affected
- Watch owners and buyers can be affected.
- Watchmakers and conservators can be affected.
- Collectors and heritage custodians can be affected.
Owners Filled
Steward
The watch owner or authorised custodian is responsible for decisions concerning its movement.

Open questions
- Does the registry's intended meaning of movement cover physical motion generally, or a narrower sense associated with this Wikidata identifier?
- Does an existing Vercy world model already own this concept, requiring this registry entry to link to it?
- Where should this entry's boundary fall for deforming bodies, distributed media and propagating patterns whose tracked position changes without a single persistent material subject?
- Which application-specific tolerances and observation windows should distinguish stationary, moving and unresolved states?
- Should the published model assume classical macroscopic motion, and which specialist models should own cases outside that regime?
