Case 42 — Comparing versions without mixing case sizes · source wording exercise
Two purported versions differ in case diameter and bracelet. How can the comparison avoid attributing every difference to a revision?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “List confirmed differences separately from seller descriptions and date the comparison…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-27959/42: address this question within its stated limits.
Case 8 — Strap compatibility: width is only the first measurement
Measure the lug opening and document bar diameter, shoulder position and strap thickness. Avoid forcing an assembly that does not fit and let a watchmaker check uncertain clearances.
Case 16 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Resolution checklist. 1) Rebalance links around the clasp. 2) Test every micro-adjust hole with each link count. 3) Check fit morning and afternoon. 4) Look for half-links by bracelet reference. 5) Accept slightly loose if the head is light. If none of that works, a strap with finer hole spacing is a reasonable conclusion, not a failure.
Wrist size changes during the day and with temperature, sometimes by several millimetres. A fit that feels tight in the afternoon may be right in the morning. Before buying parts, check the fit at different times. You may find the 'too tight' setting is only a problem a few hours a day.
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.
Case 26 — Disputed observation: is this dial colour shift real or just lighting?
Something to keep apart: sunburst and gradient dials can look like different colours depending on viewing angle, even on the same piece. A shift that appears only at certain angles is a finish effect, not a batch difference. Include a straight-on shot and one tilted shot so readers can tell the two apart.
Reader check for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: distinguish the discussion point “The core trade-off is scratch resistance…” 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: scope. Keep the stated question separate from any broader claim.
Correction note for “Comparing versions without mixing case sizes”: retain the wording beginning “Match reference, dimensions and…” 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 54 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Ask the sender or carrier for clarification; missing scans alone…” 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.
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 8 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
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.

Ask for profile shots of both case sides and a lug-top shot at an angle. Polishing shows as rounded edges, softened bevels or lug holes that look shallower than they should. Compare against a known-good reference image of the same model, not memory. A side-by-side tells you far more than a description.
Request a level straight-on image with the hands clear of the marker. Compare two independently aligned images before drawing a conclusion; an overlay cannot correct an oblique camera angle.
