Breguet Invention Timeline Lookup
Return selected Breguet-house dates for the overcoil, constant-force escapement, and tourbillon, plus explicit scope cautions.
Description
Breguet invention history includes selected regulating and power-delivery milestones.
Breguet invention history includes selected regulating and power-delivery milestones. A short timeline is not a complete catalogue of horological inventions.1
Return selected Breguet-house dates for the overcoil, constant-force escapement, and tourbillon, plus explicit scope cautions.
When to use Breguet Invention Timeline Lookup
Use this tool to return selected Breguet-house dates for the overcoil, constant-force escapement, and tourbillon, plus explicit scope cautions.
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 Breguet Invention Timeline 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 inventionFocus using the field table and calculation rules, then run the tool.
- Read inventionFocus, keyDate, 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 |
|---|---|---|---|
| inventionFocus | Breguet invention timeline focus | string; one of "overcoil", "constantForce", "tourbillon", "watchmakingLegacy", "notExhaustive" | Required |
Select an exact supported inventionFocus 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 |
|---|---|---|
| inventionFocus | Breguet invention timeline focus | string |
| keyDate | Invention date or scope | string |
| verifiedStatement | Verified Breguet invention statement | string |
{
"input": {
"inventionFocus": "tourbillon"
},
"output": {
"inventionFocus": "tourbillon",
"keyDate": "26 June 1801",
"verifiedStatement": "Breguet states that Abraham-Louis Breguet received the tourbillon-regulator patent on 26 June 1801."
}
}Limitations and assumptions
No invention priority or watch attribution is adjudicated. 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 Breguet Overcoil Terminal Curve Lookup: Return the documented geometry, date, purpose, breathing intent, or limitation of a Breguet overcoil terminal curve. For a complementary task, use Co-Axial Daniels History Lookup: Return a sourced historical fact about George Daniels's co-axial escapement attribution, patent, mechanism, or series production.
