Ask a qualified watchmaker about a suitable test for that individual case and record the test date and method. A photograph or a caseback engraving is not proof of water resistance.

Case 51 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
A tracking page has no new event after a label was created. How can the timeline be discussed without inventing a carrier explanation?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Ask the sender or carrier for clarification; missing scans alone…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-27693/51: address this question within its stated limits.
First identify the caliber, lift-angle setting, winding state and measurement position. Without those fields, the rate, amplitude and beat-error values lack enough context for a useful comparison.
Method note for “Strap compatibility: width is only the first measurement”: use “Measure the lug opening and document bar diameter,…” 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 4 — 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-24109/4: address this question within its stated limits.
Method note for “Packing photographs: document condition without exposing an address”: use “Photograph the item and protective packing…” 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 14 — QC photography: what photos actually help verify a pre-owned listing?
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.
Case 18 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Lug width is the essential one: the inside distance between the lugs where the strap fits. Measure with a ruler marked in millimetres, ideally reading it under magnification. Most watches use even numbers (18, 20, 22mm), but odd widths exist. If you measure 19 or 21, measure again and check the manufacturer spec before ordering.
Case 20 — Shipping timeline: separate dispatch, handover and scan events
Summary draft for “Shipping timeline: separate dispatch, handover and scan events”: the answer addresses “Distinguish label creation from physical acceptance and retain dated…”; the related point is “Ask the sender or carrier for clarification; missing scans alone…”. 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.
Summary draft for “Clasp photographs: what to request before judging alignment”: the answer addresses “Request open and closed views from both sides,…”; the related point is “Separate cosmetic alignment from whether the clasp engages reliably;…”. 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 51 — Comparing versions without mixing case sizes · source wording exercise
Summary draft for “Comparing versions without mixing case sizes”: the answer addresses “List confirmed differences separately from seller descriptions and date the comparison…”; the related point is “Match reference, dimensions and…”. 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.
Case 35 — Shipping timeline: separate dispatch, handover and scan events
A tracking page has no new event after a label was created. How can the timeline be discussed without inventing a carrier explanation?
Exercise RWF-10501/35: address this question within its stated limits.
Clarification for “Beginner glossary Q&A: complication, caliber, jewel count, power reserve”: the point beginning “Caliber is the movement's model designation,…” 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 2 — 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.
Power reserve is how long the watch runs from full wind until it stops. It matters if you rotate watches: a 38-hour reserve may stop over a weekend off the wrist, while 70-plus hours may not. One clarifying point is that rate stability often gets worse near the end of the reserve, so the full figure is not all precision-grade running time.
