Movement Holder Use Limitation Lookup

Return a movement-holder purpose, compatibility, support-point, clamping, or cleanliness control without treating workshop judgment as a universal specification.

Description

A movement holder stabilizes a watch movement during workshop operations.

A movement holder stabilizes a watch movement during workshop operations. Geometry, support points and clamping loads determine whether it is suitable.^[1]

Return a movement-holder purpose, compatibility, support-point, clamping, or cleanliness control without treating workshop judgment as a universal specification.

When to use Movement Holder Use Limitation Lookup

Use this tool to return a movement-holder purpose, compatibility, support-point, clamping, or cleanliness control without treating workshop judgment as a universal specification.

Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.

How to use Movement Holder Use Limitation Lookup and understand its results

Choose a supported reference focus or prepare the watch measurements, evidence and explicit limits requested. Confirm units and date conventions before running.
Enter holderFocus using the field table and calculation rules, then run the tool.
Read focus, keyConcern. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
holderFocus	Movement-holder use focus	string; one of "purpose", "compatibility", "supportPoints", "clamping", "cleanliness"	Required

Select an exact supported holderFocus value from the field table and run the lookup. The implementation selects a fixed local table entry and returns the fields shown below. Matching is case-sensitive, with no trimming, synonyms or free-text search. Any keyDate output can be a date, period or context label.

result=stored entry for selected focus

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
focus	Movement-holder use focus	string
keyConcern	Movement-holder use concern	string

json

{
  "input": {
    "holderFocus": "compatibility"
  },
  "output": {
    "focus": "compatibility",
    "keyConcern": "Use a holder intended for the movement geometry and operation. A visual match does not establish support-point, depth, or clamp compatibility."
  }
}

Limitations and assumptions

No holder fit, clamping force or condition is assessed. No sources are fetched or statements updated at runtime.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Mainspring Barrel Envelope Screen: Screen a caller-supplied mainspring radial envelope and height against barrel, arbor, and clearance dimensions without deriving the envelope from spring length, thickness, or strength. For a complementary task, use Crystal Replacement Fit Dimension Calculator: Screen replacement-crystal diameter and thickness against caller-supplied case-opening, seat-depth, and maximum-thickness dimensions.
