Case 50 — Case finishing: distinguish a reflection from a surface mark · source wording exercise
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A mark should be assessed across multiple views; aggressive polishing…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-30722/50: address this question within its stated limits.
Keep the date, work performed, provider invoice reference and test results where available. Redact addresses and payment information; do not invent service events to fill an empty history.
Case 15 — Magnetism and rate: record evidence before naming a cause
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?
Exercise RWF-29861/15: address this question within its stated limits.
Clarification for “Comparing versions without mixing case sizes”: the point beginning “Match reference, dimensions 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.
Method note for “Date window centring: compare the same date at the same angle”: use “Keep the uncropped originals alongside the detail crops and distinguish…” 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.
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved 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 101 — QC photographs: perspective or a genuinely tilted index? · comparison exercise
Reader check for “QC photographs: perspective or a genuinely tilted index?”: distinguish the discussion point “Request a level straight-on image with the hands…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: comparison. Make the basis of a comparison explicit before interpreting it.
Case 25 — Packing photographs: document condition without exposing an address
A condition record is useful but a shipping label contains personal information. How can the record be shared safely?
Exercise RWF-24597/25: address this question within its stated limits.
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 30 — 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.
Case 16 — What a water-resistance claim does and does not establish
Summary draft for “What a water-resistance claim does and does not establish”: the answer addresses “Ask a qualified watchmaker about a suitable test for that individual…”; the related point is “A photograph or a caseback engraving is not…”. 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.
Method note for “Reading a timegrapher recording without losing the context”: use “Keep the complete recording and ask for the…” 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 20 — Movement identification: the limits of a rotor photograph
Limit of the answer in “Movement identification: the limits of a rotor photograph”: “Describe visible bridge shapes and markings separately…” 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.
Record lug-to-lug and the effective span including rigid end links. Use a similar camera distance and neutral wrist position; photographs support fit discussion but do not replace measurements.
Case 9 — Lume comparison: keep exposure and charging conditions consistent
Two glowing dials are shown with different camera exposure and unknown charging time. What can the images establish?
Exercise RWF-13622/9: address this question within its stated limits.
