Carrousel Tourbillon Architecture Screen

Screen a rotating regulator as tourbillon-like or carrousel-like from supplied cage and seconds-hand architecture features.

Description

Rotating-regulator architecture can be screened from where the regulator sits and whether its cage couples to the seconds hand.

Rotating-regulator architecture can be screened from where the regulator sits and whether its cage couples to the seconds hand. The labels describe supplied features.^[1]

Screen a rotating regulator as tourbillon-like or carrousel-like from supplied cage and seconds-hand architecture features.

When to use Carrousel Tourbillon Architecture Screen

Use this tool to screen a rotating regulator as tourbillon-like or carrousel-like from supplied cage and seconds-hand architecture features.

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 Carrousel Tourbillon Architecture Screen 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 cageCoupledToSecondsHand, cageRotationPeriodSeconds, regulatorMountedInCage using the field table and calculation rules, then run the tool.
Read architectureScreen, cageRevolutionsPerDay, classificationCaution. 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
cageCoupledToSecondsHand	Cage coupled to seconds indication	boolean	Required
cageRotationPeriodSeconds	Cage rotation period (s)	number; minimum: 0	Required
regulatorMountedInCage	Balance and escapement mounted in cage	boolean	Required

Enter positive cage seconds and two booleans. Return notARotatingRegulator if not mounted in the cage; otherwise tourbillonLike when coupled to seconds, else carrouselLike. Return rotation rate and caution.

revolutionsPerDay=86,400/cagePeriod

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

Output field	Meaning	Value type
architectureScreen	Rotating architecture screen	string; one of "tourbillonLike", "carrouselLike", "notARotatingRegulator"
cageRevolutionsPerDay	Cage revolutions per day (rev/day)	number; minimum: 0
classificationCaution	Classification caution	string

  "input": {
    "cageCoupledToSecondsHand": true,
    "cageRotationPeriodSeconds": 60,

  "output": {

    "classificationCaution": "This is a feature-based architecture screen; specific calibers can combine features or use nonstandard drive arrangements."
  }
}

Limitations and assumptions

Nonstandard calibers need separate examination; no mechanism is inspected or accuracy benefit inferred.

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

Alternative or Complementary methods

Use GMT Jumping Versus Dragging Mechanism Screen: Screen a caller-described hour display as jumping, dragged, continuous, or ambiguous using observed mechanism features. For a complementary task, use Escapement Impulse Rate: Compare detent, duplex, and natural-escapement impulse rates from the balance beat rate without conflating beat and full oscillation.
