Method note for “Crystal reflections: why a dark patch is not a coating test”: use “No single lighting setup settles…” 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 124 — First QC request: the minimum useful information · documentation exercise
Summary draft for “First QC request: the minimum useful information”: the answer addresses “Include complete instrument settings where relevant and say…”; the related point is “State the model configuration, the specific concern and…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: documentation. Distinguish an original record from a proposed record format.
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?
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.
Exercise RWF-21920/8: address this question within its stated limits.
Limit of the answer in “Packing photographs: document condition without exposing an address”: “Photograph the item and protective packing…” 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 39 — QC photography: what photos actually help verify a pre-owned listing? · source wording exercise
Summary draft for “QC photography: what photos actually help verify a pre-owned listing?”: the answer addresses “Flash flattens printing and hides…”; the related point is “Diffuse light shows print edges, alignment…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
Case 20 — QC photography: what photos actually help verify a pre-owned listing?
Ask for profile shots of both case sides and a lug-top shot at an angle. Polishing shows as rounded edges, softened bevels or lug holes that look shallower than they should. Compare against a known-good reference image of the same model, not memory. A side-by-side tells you far more than a description.
Case 19 — Model comparison: dive bezel action and alignment, how to compare fairly
On alignment, a clarifying point: is the misalignment visible straight on, or only from an angle? Parallax on a raised bezel can make a perfectly aligned pip look half a click off when viewed slightly from the side. Photograph straight above the dial before calling it misaligned.
Method note for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: use “First identify the caliber, lift-angle setting, winding…” 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.
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.
Case 31 — Disputed observation: is this dial colour shift real or just lighting?
Status for now: unresolved. The claim is plausible, but no controlled comparison has been posted. Until one appears, describe it as 'reported, not verified'. When someone posts a same-frame, grey-card comparison under two lighting conditions, the thread can update the status with a date and a link to that post.
Clarifying question for the thread: is the goal to check authenticity, condition, or both? For condition, the request list above is enough. For authenticity, you also need caseback, serial or reference engravings, and ideally movement photos. Movement photos usually require opening the watch, which a seller may reasonably refuse without a watchmaker present.
Case 8 — Bracelet fit: measuring the usable clasp adjustment
Record wrist circumference, removable links and the clasp adjustment range in millimetres. Request the closed bracelet circumference rather than inferring it from marketing dimensions.
Summary draft for “Maintenance question: how do I tell if an automatic actually needs service?”: the answer addresses “The calendar interval is a conservative…”; the related point is “Useful signs, in rough order of seriousness: power reserve noticeably shorter…”. 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 “Seller review template: facts, dates and unresolved questions”: the point beginning “Use fields for order date, promised terms, dated…” 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.
