Case 9 — Comparing dial colour under different lighting
Summary draft for “Comparing dial colour under different lighting”: the answer addresses “State the lighting and…”; the related point is “Compare controlled images where available and avoid calling a…”. 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.
Limit of the answer in “Crystal reflections: why a dark patch is not a coating test”: “Compare multiple controlled angles and describe the visible observation without asserting…” 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.
Differences in pigment, applied area, thickness and colour can affect appearance. Keep those design differences separate from claims about quality and use matched conditions for any comparison.
Case 35 — Packing photographs: document condition without exposing an address
Clarification for “Packing photographs: document condition without exposing an address”: the point beginning “Photograph the item and protective packing…” 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.
Correction note for “Maintenance question: how do I tell if an automatic actually needs service?”: retain the wording beginning “Useful signs, in rough order of seriousness: power reserve noticeably shorter…” 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 15 — Service enquiry: information a watchmaker can use
A service question only says that the watch stops occasionally. Which observations make an initial enquiry more useful?
Exercise RWF-28769/15: address this question within its stated limits.
Case 31 — Disputed observation: is this dial colour shift real or just lighting?
Suggested protocol. 1) Both dials in one frame. 2) Diffuse daylight, no direct sun, plus a second shot under neutral indoor light. 3) Grey card visible. 4) No filters, no editing. 5) State camera settings if known. If both shots show the same direction of difference, the claim is supported. If the difference flips between lighting conditions, it's most likely lighting.
Case 41 — Magnetism and rate: record evidence before naming a cause · source wording exercise
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A competent watchmaker can test and diagnose it; random adjustment…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-25839/41: address this question within its stated limits.
Summary. Pick sapphire for scratch resistance in low-impact use, acrylic for impact tolerance and easy polishing, and mineral as a low-cost middle option. Prefer inner-surface AR if you're worried about wear. Look at crystal profile when comparing thickness. Choose by how you'll use the watch, not by the material label.
Case 19 — QC checklist: prioritise observable faults over pixel hunting
Method note for “QC checklist: prioritise observable faults over pixel hunting”: use “Start with function, legibility, assembly 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.
Use fields for order date, promised terms, dated communications, delivery evidence and resolution. Leave unsupported fields blank and separate observations from opinions; this reference is not a seller endorsement.
Case 11 — Model comparison: dive bezel action and alignment, how to compare fairly
Summary table proposal: click count, back-play (none, slight, noticeable), click consistency around the rotation, and alignment (straight-on photo, offset in fractions of a click). With that, the thread can compare actual properties instead of trading adjectives. Dated corrections welcome below.
Case 11 — Bracelet fit: measuring the usable clasp adjustment
Limit of the answer in “Bracelet fit: measuring the usable clasp adjustment”: “Record wrist circumference, removable links and the clasp…” 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 16 — Model comparison: dive bezel action and alignment, how to compare fairly
Summary table proposal: click count, back-play (none, slight, noticeable), click consistency around the rotation, and alignment (straight-on photo, offset in fractions of a click). With that, the thread can compare actual properties instead of trading adjectives. Dated corrections welcome below.
Case 21 — Maintenance question: how do I tell if an automatic actually needs service?
Sealing and movement performance are separate questions. Ask a qualified watchmaker about inspection and testing appropriate to the particular watch and its intended use; a healthy rate does not establish water resistance.
