Pocket Watch Up Down Power Indicator Lookup
Return the patent history, winding-state meaning, differential-train operation, or terminology scope of a pocket-watch UP/DOWN indicator.
Description
An UP/DOWN power indicator displays winding state and impending run-down in a mechanism-specific way.
An UP/DOWN power indicator displays winding state and impending run-down in a mechanism-specific way. Its scale is not a universal remaining-hours estimate.1
Return the patent history, winding-state meaning, differential-train operation, or terminology scope of a pocket-watch UP/DOWN indicator.
When to use Pocket Watch Up Down Power Indicator Lookup
Use this tool to return the patent history, winding-state meaning, differential-train operation, or terminology scope of a pocket-watch UP/DOWN indicator.
Choose a supported lookup focus or prepare the measured values, documented evidence and caller-selected limits requested. Use the exact field names and confirm their units or date format.
How to use Pocket Watch Up Down Power Indicator Lookup and understand its results
- Choose a supported lookup focus or prepare the measured values, documented evidence and caller-selected limits requested. Use the exact field names and confirm their units or date format.
- Enter indicatorFocus using the field table and calculation rules, then run the tool.
- Read indicatorFocus, 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 |
|---|---|---|---|
| indicatorFocus | Pocket watch UP/DOWN indicator focus | string; one of "history", "meaning", "operation", "terminology" | Required |
Select one supported focus from the input table and run the lookup. Match the exact case-sensitive enum value; no trimming, synonyms or free-text search is applied. Return the selected focus and its stored indicator meaning/history statement and historical/context label. keyDate, where present, can be a historical date, period or contextual label rather than a parseable date.
result=stored entry for exact selected focus Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| indicatorFocus | Pocket watch UP/DOWN indicator focus | string |
| keyDate | Key date or context | string |
| verifiedStatement | Verified UP/DOWN statement | string |
{
"input": {
"indicatorFocus": "history"
},
"output": {
"indicatorFocus": "history",
"keyDate": "18 May 1879",
"verifiedStatement": "A. Lange & Söhne states that its patent No. 9349 described a pocket-watch device for recognizing whether the watch was wound or unwound and indicating time remaining before complete unwinding."
}
}Limitations and assumptions
No mainspring state, remaining hours or individual indicator mechanism is measured or authenticated. This is a fixed local table; it does not fetch sources or update statements at runtime.
Numeric inputs 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 Watch Winder Rotation Direction Lookup: Return clockwise, counterclockwise, or programmed alternating winder direction while withholding a universal turns-per-day setting. For a complementary task, use Power Reserve Torque Decay Curve Reader: Linearly interpolate torque on a caller-supplied measured curve and report its decline, ratio, and monotonicity.
