Case 22 — Comparing dial colour under different lighting
Clarification for “Comparing dial colour under different lighting”: the point beginning “State the lighting 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: scope. Keep the stated question separate from any broader claim.
Case 26 — Reading a timegrapher recording without losing the context
The supplied screen shows a rate but does not identify the lift angle, position or winding state. Which observations should accompany the recording?
Exercise RWF-24433/26: address this question within its stated limits.
Case 23 — Case finishing: distinguish a reflection from a surface mark
Summary draft for “Case finishing: distinguish a reflection from a surface mark”: the answer addresses “Ask for photographs with the light moved and…”; the related point is “A mark should be assessed across multiple views; aggressive polishing…”. 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 14 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
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.
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 18 — Lug-to-lug and end-link overhang in wrist photographs
Correction note for “Lug-to-lug and end-link overhang in wrist photographs”: retain the wording beginning “Record lug-to-lug and the effective span…” 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.
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Use the same numeral, camera axis…” 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 26 — Movement identification: the limits of a rotor photograph
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Describe visible bridge shapes and markings separately…”; the related point is “Ask a qualified watchmaker to inspect it if identification matters for…”. 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 19 — QC photography: what photos actually help verify a pre-owned listing?
When asking a seller for extra photos of a pre-owned watch, what shots are actually useful as evidence? Listings tend to have glossy angled photos that hide more than they show. I'd like a standard request list the forum can reuse.
Exercise RWF-13522/19: address this question within its stated limits.
Case 39 — Lume questions: why does my lume fade so quickly, and how should I compare it? · source wording exercise
Summary draft for “Lume questions: why does my lume fade so quickly, and how should I compare it?”: the answer addresses “Afterglow fades fastest in the first minutes and then settles to…”; the related point is “The real question is whether it's readable after an hour in…”. 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.
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.
A caution: photos can't settle everything. Water resistance, timekeeping and internal condition aren't visible in any image. A short timegrapher video or a stated recent rate test adds information, but treat it as a seller claim unless an independent party confirms it. Photos narrow the risk. They don't remove it.
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
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: scope. Keep the stated question separate from any broader claim.
Case 4 — A maintenance log that remains useful after a sale
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.
