Case 73 — Movement identification: the limits of a rotor photograph · comparison exercise
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Review focus: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Describe visible bridge shapes and markings separately…” as the discussion anchor; no new event or result is supplied.

Case 6 — Maintenance question: how do I tell if an automatic actually needs service?
Clarifying question first: do you have a baseline? If you've never recorded the watch's rate or power reserve, 'drifting' is hard to judge. Start a simple log now with daily offset against a reference time for a week, and the hours it runs from full wind. Once you have that, later changes mean something.
Case 258 — Crown operation: when a forum cannot diagnose the resistance · reader check exercise
A description of stiffness does not establish the cause. What information is safe and useful to collect before an inspection?
Review focus: reader check. State what a new reader can and cannot infer from this exercise. Use the original answer fragment “Stop forcing it and arrange inspection rather than trying…” as the discussion anchor; no new event or result is supplied.

Case 44 — Crown operation: when a forum cannot diagnose the resistance · source wording exercise
Method note for “Crown operation: when a forum cannot diagnose the resistance”: use “Stop forcing it and arrange inspection rather than trying…” 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.
Case 1 — Strap compatibility: width is only the first measurement
Two straps share the same nominal width but differ in thickness and spring-bar clearance. Which dimensions need checking?
Exercise RWF-23493/1: address this question within its stated limits.
Case 30 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Clarifying question: what does daily wear mean for you? Desk work, manual labour or sports change the answer. For desk use, sapphire's scratch resistance is the main benefit. For work with frequent knocks, a slightly domed acrylic that you can polish may last longer in practice, despite the scratches.
Start with how you measured it. Comparing against a phone clock once a day for a week, at the same time, and noting the offset is reliable enough. One 24-hour reading isn't, because rate depends on wrist time, position overnight and state of wind. Average across several days before deciding anything.
Case 22 — 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.
The calendar interval is a conservative default, not a rule. Useful signs, in rough order of seriousness: power reserve noticeably shorter than spec from full wind, rate drifting outside its usual range, the watch stopping on the wrist, gritty or rough winding, and the date changing slowly or late.
Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “Record the change and the circumstances without treating…” 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 9 — Magnetism and rate: record evidence before naming a cause
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “Record the change and the circumstances without treating…” 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 32 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.

Case 21 — Forum comparison archive: link the evidence and the correction
Limit of the answer in “Forum comparison archive: link the evidence and the correction”: “Add a dated correction near the original conclusion…” 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.
Method note for “First QC request: the minimum useful information”: use “State the model configuration, the specific concern and…” 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 32 — Case finishing: distinguish a reflection from a surface mark
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.
