Two straps share the same nominal width but differ in thickness and spring-bar clearance. Which dimensions need checking?
Discussion record: RWF-01389.
Clarification for “Strap compatibility: width is only the first measurement”: the point beginning “Measure the lug opening and document bar diameter,…” belongs to the question as written. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: scope. Keep the stated question separate from any broader claim.
Measure the lug opening and document bar diameter, shoulder position and strap thickness. Avoid forcing an assembly that does not fit and let a watchmaker check uncertain clearances.
Method note for “Strap compatibility: width is only the first measurement”: use “Measure the lug opening and document bar diameter,…” as a row heading in a proposed working record. Put the statement, its supporting source or measurement, and any unresolved detail in separate fields. This proposes a format; it supplies no additional evidence. Keep the stated question separate from any broader claim.
