Case Geometry Loss Pattern Screen
Screen measured case-geometry loss against a reference dimension and explicit percentage limit without treating the result as an originality verdict.
Description
Case geometry loss compares a current thickness with a documented reference.
Case geometry loss compares a current thickness with a documented reference. The percentage is normalized to the original dimension.1
Screen measured case-geometry loss against a reference dimension and explicit percentage limit without treating the result as an originality verdict.
When to use Case Geometry Loss Pattern Screen
Use this tool to screen measured case-geometry loss against a reference dimension and explicit percentage limit without treating the result as an originality verdict.
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 Case Geometry Loss Pattern 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 currentMeasuredThicknessMillimeters, maximumAllowedLossPercent, referenceOriginalThicknessMillimeters using the field table and calculation rules, then run the tool.
- Read absoluteThicknessLossMillimeters, geometryCaution, thicknessLossPercent, withinCallerLossLimit. 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 |
|---|---|---|---|
| currentMeasuredThicknessMillimeters | Current measured geometry thickness (mm) | number; minimum: 0 | Required |
| maximumAllowedLossPercent | Maximum allowed geometry loss (%) | number; minimum: 0 | Required |
| referenceOriginalThicknessMillimeters | Documented original reference thickness (mm) | number; minimum: 0 | Required |
Enter positive current/reference mm with current≤reference and nonnegative percent ceiling. Return loss, percentage and gate allowing eight machine-epsilon-scaled units of numerical tolerance around the ceiling.
loss=reference−current; loss%=100loss/reference Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| absoluteThicknessLossMillimeters | Absolute geometry loss (mm) | number; minimum: 0 |
| geometryCaution | Geometry evidence caution | string |
| thicknessLossPercent | Geometry loss percent (%) | number; minimum: 0 |
| withinCallerLossLimit | Within caller geometry-loss limit | boolean |

},
"output": {
"absoluteThicknessLossMillimeters": 0.10000000000000009,
"geometryCaution": "A geometry-loss screen can flag dimensional loss for a documented reference condition; it cannot prove over-polishing, patina authenticity, or originality from one measurement.",

}
}Limitations and assumptions
No over-polishing, originality or reference authenticity is established.
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. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
