Case 13 — Crystal reflections: why a dark patch is not a coating test
A dark area appears at an oblique angle in a single photograph. Does that establish a coating difference?

Limit of the answer in “What a water-resistance claim does and does not establish”: “Ask a qualified watchmaker about a suitable test for that individual…” 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.
A stated water-resistance rating does not establish the present condition of an individual watch. Separate the manufacturer specification from a dated inspection or test of the particular example.
Case 38 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
Method note for “Shipping timeline: separate dispatch, handover and scan events”: use “Ask the sender or carrier for clarification; missing scans alone…” 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.
Method note for “A maintenance log that remains useful after a sale”: use “Keep the date, work performed, provider invoice reference…” 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.
Describe whether resistance occurs during winding or setting and whether the crown engages consistently. Stop forcing it and arrange inspection rather than trying an unverified repair from a thread.
Case 28 — 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.
Case 17 — Case finishing: distinguish a reflection from a surface mark
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?

Case 15 — Comparing versions without mixing case sizes
Summary draft for “Comparing versions without mixing case sizes”: the answer addresses “Match reference, dimensions and…”; the related point is “List confirmed differences separately from seller descriptions and date the comparison…”. 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.
Add lug-to-lug, thickness and lug width as separate rows. Diameter alone tells you little about wearability. Two cases 2mm apart in diameter can be within 1mm of each other lug to lug, and that number decides whether the watch overhangs a small wrist. Also give the source for each figure: manufacturer sheet, caliper measurement, or catalogue listing.
Clarification for “What a water-resistance claim does and does not establish”: the point beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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.
Thickness matters more than people expect. Straps around 4 to 5mm at the lugs can hit the case or stop the strap folding down on watches with short lugs or tight lug-to-case clearance. Do you know whether your watch has drilled lugs or a tight gap between strap and case? That tells you how much thickness is safe.
Case 45 — Reading a timegrapher recording without losing the context · source wording exercise
Clarification for “Reading a timegrapher recording without losing the context”: the point beginning “A single number cannot establish service condition, movement identity…” 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.
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
Case 18 — Comparing dial colour under different lighting
One image was taken beside a window and the other under a warm lamp. How should a colour comparison be qualified?
