A practical test without a camera: charge both watches the same way, sit in a dark room, and check readability at 5 minutes, 30 minutes and 2 hours. Write down which you can still read the time on. It's subjective but repeatable, and more useful than a single photo.

Case 13 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Wrist size changes during the day and with temperature, sometimes by several millimetres. A fit that feels tight in the afternoon may be right in the morning. Before buying parts, check the fit at different times. You may find the 'too tight' setting is only a problem a few hours a day.
Limit of the answer in “First QC request: the minimum useful information”: “Include complete instrument settings where relevant and say…” 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 44 — Maintenance question: how do I tell if an automatic actually needs service? · source wording exercise
Common advice says service every five years, but service is expensive and some people run watches much longer. What observable signs actually indicate a mechanical watch needs attention, as opposed to just being due on a calendar?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Useful signs, in rough order of seriousness: power reserve noticeably shorter…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-26818/44: address this question within its stated limits.
Case 22 — Lug-to-lug and end-link overhang in wrist photographs
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Record lug-to-lug and the effective span…” 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.
Case 7 — First QC request: the minimum useful information
What should an initial QC request include so replies can address the actual question?
Exercise RWF-24258/7: address this question within its stated limits.
Case 26 — Crown operation: when a forum cannot diagnose the resistance
Summary draft for “Crown operation: when a forum cannot diagnose the resistance”: the answer addresses “Describe whether resistance occurs during winding or setting and…”; the related point is “Stop forcing it and arrange inspection rather than trying…”. 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.
Clarification for “Case finishing: distinguish a reflection from a surface mark”: the point beginning “Ask for photographs with the light moved and…” 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: source wording. Retain the source wording beside any paraphrase.
Proposed reusable request list. 1) Straight dial, diffuse light, hands clear of markers. 2) Both case profiles. 3) Lug tops at an angle. 4) Caseback and engravings. 5) Clasp and bracelet end links. 6) Dated note in frame. Optional: timegrapher reading or movement photos. Add or change items with a reason, and I'll keep the list current.
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.
Correction note for “Magnetism and rate: record evidence before naming a cause”: retain the wording beginning “A competent watchmaker can test and diagnose it; random adjustment…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
Case 26 — Forum comparison archive: link the evidence and the correction
Add a dated correction near the original conclusion and link the new evidence. Preserve the reasoning trail instead of silently replacing an uncertain claim with a confident one.
Case 8 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The lift angle must match the movement specification for the amplitude reading to be meaningful. If it is unknown, label amplitude as provisional instead of accepting the instrument default.
Document when it stops, winding behaviour, recent impacts and the positions in which it happens. Be honest about the watch and request an assessment before approving work or ordering parts.
Case 32 — Shipping timeline: separate dispatch, handover and scan events
Distinguish label creation from physical acceptance and retain dated event text with personal details removed. Ask the sender or carrier for clarification; missing scans alone do not establish loss or seizure.
