Case 15 — Comparing dial colour under different lighting
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.
Case 14 — Case finishing: distinguish a reflection from a surface mark
Correction note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “Ask for photographs with the light moved 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.
The calendar interval is a conservative default, not a rule. Useful signs, in rough order of seriousness: power reserve noticeably shorter than spec from full wind, rate drifting outside its usual range, the watch stopping on the wrist, gritty or rough winding, and the date changing slowly or late.
Case 44 — QC photographs: perspective or a genuinely tilted index? · source wording exercise
A marker can look tilted when the camera is above the dial axis. What extra image would separate perspective from an assembly issue?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Compare two independently aligned images before drawing a conclusion; an overlay…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-21138/44: address this question within its stated limits.
Clarification for “Packing photographs: document condition without exposing an address”: the point beginning “Photograph the item and protective packing…” 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 16 — 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.
Case 5 — Bracelet fit: measuring the usable clasp adjustment
A nominal case diameter says little about a bracelet that cannot be shortened enough. How should a sizing question be documented?
Exercise RWF-16355/5: address this question within its stated limits.
Case 24 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
A notation like 20/16 means 20mm at the lugs, tapering to 16mm at the buckle. Taper affects look and comfort more than fit. A strong taper suits smaller and dressier cases, a straight strap suits sport watches. Your buckle or clasp also has to match the narrow end, so check that if you want to reuse an existing buckle.
Start with function, legibility, assembly and clear visible damage. Explain what the full-size image shows, what the crop adds and what remains uncertain; do not turn an overlay into an automatic verdict.
Case 28 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.
Exercise RWF-12792/28: address this question within its stated limits.
Summary order of importance. 1) Lug width, measured between the lugs. 2) Lug-end thickness against clearance. 3) Spring bar diameter. 4) Taper and buckle width. 5) Length, which is usually given as long side / short side in mm and should be compared with a strap that already fits you.
Case 37 — Bracelet fit: measuring the usable clasp adjustment · source wording exercise
A nominal case diameter says little about a bracelet that cannot be shortened enough. How should a sizing question be documented?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Request the closed bracelet circumference rather than inferring…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-09267/37: address this question within its stated limits.
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 21 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.
Exercise RWF-06607/21: address this question within its stated limits.
Caliber is the movement's model designation, like a part number. Two watches from different brands can share the same caliber family with different finishing or regulation. On a spec sheet it tells you what's inside and roughly what service parts are available. It doesn't tell you how well that particular example was adjusted.
