Free Sprung Index Regulator Comparison Lookup
Return free-sprung inertia adjustment, index curb-pin adjustment, isochronism control, service tradeoff, or non-absolute accuracy fact.
Description
Free-sprung regulation adjusts balance inertia, while an index regulator changes active spring length.
Free-sprung regulation adjusts balance inertia, while an index regulator changes active spring length. Architecture alone does not determine accuracy.1
Return free-sprung inertia adjustment, index curb-pin adjustment, isochronism control, service tradeoff, or non-absolute accuracy fact.
When to use Free Sprung Index Regulator Comparison Lookup
Use this tool to return free-sprung inertia adjustment, index curb-pin adjustment, isochronism control, service tradeoff, or non-absolute accuracy fact.
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 Free Sprung Index Regulator Comparison 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 comparisonFocus using the field table and calculation rules, then run the tool.
- Read comparisonFocus, 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 |
|---|---|---|---|
| comparisonFocus | Free-sprung versus index regulator focus | string; one of "freeSprungAdjustment", "indexAdjustment", "isochronismAdjustment", "serviceTradeoff", "accuracyClaimCaution" | Required |
Select an exact supported comparisonFocus 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 |
|---|---|---|
| comparisonFocus | Free-sprung versus index regulator focus | string |
| keyDate | Regulator context | string |
| verifiedStatement | Verified regulator statement | string |

"verifiedStatement": "Grand Seiko describes a free-sprung system without a regulator index; balance screws alter moment of inertia to fine-tune rate."

}Limitations and assumptions
No regulator is identified or adjusted, and no system is ranked universally superior. 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 Isochronism Amplitude Rate Slope Calculator: Measure the endpoint rate change and slope between two caller-supplied amplitude observations; this does not turn a two-point slope into a complete isochronism curve. For a complementary task, use Hairspring Concentric Breathing Change Calculator: Calculate the diameter envelope of a modeled concentric breathing hairspring excursion without inferring spring geometry from a terminal-curve name.
