Case 30 — Comparing versions without mixing case sizes
Two purported versions differ in case diameter and bracelet. How can the comparison avoid attributing every difference to a revision?
Exercise RWF-25919/30: address this question within its stated limits.
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 22 — Comparing dial colour under different lighting
State the lighting and white-balance limitations. Compare controlled images where available and avoid calling a colour defect from differently processed photographs.
Method note for “Magnetism and rate: record evidence before naming a cause”: use “Record the change and the circumstances without treating…” 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.
Clarifying question: does anyone in the thread have access to both versions at once? Without simultaneous comparison, every claim either way is weak evidence. If not, the next best option is photos with a grey card in frame and white balance locked or set manually, which at least makes separate photos roughly comparable.
Case 46 — Lug-to-lug and end-link overhang in wrist photographs · source wording exercise
Method note for “Lug-to-lug and end-link overhang in wrist photographs”: use “Use a similar camera distance and neutral wrist position; photographs support…” 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 25 — Crystal reflections: why a dark patch is not a coating test
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. Keep the stated question separate from any broader claim.
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Case 33 — 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.
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 13 — Clasp photographs: what to request before judging alignment
Clarification for “Clasp photographs: what to request before judging alignment”: the point beginning “Request open and closed views from both sides,…” 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.
Separate three properties: click count (60 or 120 positions), feel (how firm each click is, and whether there's back-play), and alignment (whether the pip lines up with the 12 o'clock marker at rest). Crisp vs mushy is mostly about feel and back-play. Alignment can be measured, so treat it separately.
Case 25 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The reported numbers alone do not establish damage or the need for service. Confirm the setup, collect comparable readings and ask a watchmaker to assess a concerning or changing pattern.
Clarification for “Bracelet fit: measuring the usable clasp adjustment”: the point beginning “Record wrist circumference, removable links and the clasp…” 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 20 — Case finishing: distinguish a reflection from a surface mark
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.
