Case 26 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
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.
Case 32 — QC photographs: perspective or a genuinely tilted index?
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.
Case 22 — QC photography: what photos actually help verify a pre-owned listing?
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 213 — What a water-resistance claim does and does not establish · correction exercise
A listing describes a water-resistance rating but provides no test record for the individual watch. What evidence would address the gap?
Review focus: correction. Preserve the old wording if a later source changes the interpretation. Use the original answer fragment “A photograph or a caseback engraving is not…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-25905/213: address this question within its stated limits.
Limit of the answer in “Reading a timegrapher recording without losing the context”: “Keep the complete recording and ask for the…” 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 26 — 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.
Case 30 — Shipping timeline: separate dispatch, handover and scan events
Distinguish label creation from physical acceptance and retain dated event text with personal details removed. Ask the sender or carrier for clarification; missing scans alone do not establish loss or seizure.
Case 48 — Service enquiry: information a watchmaker can use · source wording exercise
Correction note for “Service enquiry: information a watchmaker can use”: retain the wording beginning “Be honest about the watch and request an assessment…” 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. Retain the source wording beside any paraphrase.
A complication is any function beyond hours, minutes and seconds. A date window counts, technically, and so do a chronograph, GMT hand or moon phase. More complications usually mean more parts, more thickness and more service cost. For a first everyday watch, decide which functions you'd really use before treating them as value.
Case 35 — 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-18708/35: address this question within its stated limits.
Case 15 — Magnetism and rate: record evidence before naming a cause
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.
Case 17 — 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-16063/17: address this question within its stated limits.
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.
Separate preference from a potential functional problem. Inconsistent engagement, slipping or uncertain alignment should be documented and checked against the design’s specification by a competent watchmaker; do not invent a universal defect threshold.
Case 22 — A maintenance log that remains useful after a sale
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.
