Record wrist circumference, removable links and the clasp adjustment range in millimetres. Request the closed bracelet circumference rather than inferring it from marketing dimensions.

Case 44 — Movement identification: the limits of a rotor photograph · source wording exercise
Method note for “Movement identification: the limits of a rotor photograph”: use “Ask a qualified watchmaker to inspect it if identification matters for…” 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. Retain the source wording beside any paraphrase.
Micro-adjust spacing varies by clasp. Measure the actual change at each setting rather than assuming a standard number of millimetres; compare the usable range with the link length.
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Case 5 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
One method that often helps without any service is using overnight resting position to cancel daily drift. Many watches gain in some positions and lose in others. If yours loses on the wrist, try leaving it crown up or dial up overnight and log the result for a few nights. Some people get close to zero this way.
Record lug-to-lug and the effective span including rigid end links. Use a similar camera distance and neutral wrist position; photographs support fit discussion but do not replace measurements.

Case 22 — Movement identification: the limits of a rotor photograph
Method note for “Movement identification: the limits of a rotor photograph”: use “Describe visible bridge shapes and markings separately…” 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.
Case 26 — Service enquiry: information a watchmaker can use
Summary draft for “Service enquiry: information a watchmaker can use”: the answer addresses “Document when it stops, winding behaviour, recent impacts and…”; the related point is “Be honest about the watch and request an assessment…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: scope. Keep the stated question separate from any broader claim.
Case 12 — Comparing dial colour under different lighting
Limit of the answer in “Comparing dial colour under different lighting”: “State the lighting and…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: scope. Keep the stated question separate from any broader claim.
Case 33 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Regulation is possible if you want it closer. On many movements it's a quick adjustment by a watchmaker. Can you check whether the losing rate is consistent or getting worse? A stable -8 is a good candidate for simple regulation. A growing loss points to something else, such as falling amplitude, and regulation alone won't fix that.

Clarification for “A maintenance log that remains useful after a sale”: the point beginning “Keep the date, work performed, provider invoice reference…” 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.
Differences in pigment, applied area, thickness and colour can affect appearance. Keep those design differences separate from claims about quality and use matched conditions for any comparison.
Treat the comparison as inconclusive. Repeat with equal light source, charging duration, elapsed time and camera settings; disclose conditions rather than assigning an unsupported quality score.
