Escapement Contact Friction Comparison Calculator
Compare caller-measured lubricated, unlubricated, and silicon-contact friction; lubricant-free operation does not mean zero friction or universal superiority.
Description
Contact-friction comparison uses measured values, separating change relative to an unlubricated reference from change relative to a lubricated contact.
Contact-friction comparison uses measured values, separating change relative to an unlubricated reference from change relative to a lubricated contact.1
Compare caller-measured lubricated, unlubricated, and silicon-contact friction; lubricant-free operation does not mean zero friction or universal superiority.
When to use Escapement Contact Friction Comparison Calculator
Use this tool to compare caller-measured lubricated, unlubricated, and silicon-contact friction; lubricant-free operation does not mean zero friction or universal superiority.
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 Escapement Contact Friction Comparison Calculator 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 lubricatedContactFrictionMillinewtons, referenceUnlubricatedFrictionMillinewtons, siliconContactFrictionMillinewtons using the field table and calculation rules, then run the tool.
- Read frictionReductionPercent, reductionVersusLubricatedMillinewtons, relativeToUnlubricatedFriction. 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 |
|---|---|---|---|
| lubricatedContactFrictionMillinewtons | Lubricated reference contact friction (mN) | number; minimum: 0 | Required |
| referenceUnlubricatedFrictionMillinewtons | Reference unlubricated contact friction (mN) | number; minimum: 0 | Required |
| siliconContactFrictionMillinewtons | Silicon contact friction measurement (mN) | number; minimum: 0 | Required |
Enter nonnegative forces in mN with reference strictly greater than lubricated friction. Return reduction percentage, lubricated difference and silicon/reference ratio. Negative reductions are allowed.
reduction%=100(reference−silicon)/reference; lubricatedDifference=lubricated−silicon Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| frictionReductionPercent | Reduction versus unlubricated reference (%) | number |
| reductionVersusLubricatedMillinewtons | Reduction versus lubricated baseline (mN) | number |
| relativeToUnlubricatedFriction | Silicon friction relative to unlubricated reference | number; minimum: 0 |

}Limitations and assumptions
No friction is measured and lubricant-free operation is not assumed to mean zero friction.
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.
