Guilloché Perlage Pattern Family Lookup

Classify guilloché, Clous de Paris, perlage, their relationship, and hand-versus-machine execution without treating distinct finish families as synonyms.

Description

Guilloché is an engraving family, Clous de Paris is a motif within it, and perlage is circular graining.

Guilloché is an engraving family, Clous de Paris is a motif within it, and perlage is circular graining. Pattern and manufacturing method are separate classifications.^[1]

Classify guilloché, Clous de Paris, perlage, their relationship, and hand-versus-machine execution without treating distinct finish families as synonyms.

When to use Guilloché Perlage Pattern Family Lookup

Use this tool to classify guilloché, Clous de Paris, perlage, their relationship, and hand-versus-machine execution without treating distinct finish families as synonyms.

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 Guilloché Perlage Pattern Family 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 patternFocus using the field table and calculation rules, then run the tool.
Read keyDate, patternFocus, verifiedStatement. 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
patternFocus	Guilloché or perlage pattern focus	string; one of "guilloche", "clousDeParis", "perlage", "relationship", "execution"	Required

Select an exact supported patternFocus 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
keyDate	Taxonomy or process status	string
patternFocus	Guilloché or perlage pattern focus	string
verifiedStatement	Verified watch-pattern statement	string

  "input": {
    "patternFocus": "relationship"
  },
  "output": {
    "keyDate": "taxonomy",

    "verifiedStatement": "Guilloché describes the broader engraving technique, Clous de Paris is a guilloché motif, and perlage is a separate circular surface finish rather than a synonym."

}

Limitations and assumptions

No finish is inspected and a motif name does not establish hand execution. 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.
