Case 41 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me? · source wording exercise
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.
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Without those fields, the rate, amplitude and beat-error values lack…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-27179/41: address this question within its stated limits.
Case 53 — 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.

Case 18 — Lug-to-lug and end-link overhang in wrist photographs
A wide-angle wrist photo exaggerates the nearest edge of the case. How can two watches be compared fairly?
Exercise RWF-24807/18: address this question within its stated limits.
Clarification for “A maintenance log that remains useful after a sale”: the point beginning “Keep the date, work performed, provider invoice reference…” 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.
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.
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.
Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “Record the change and the circumstances without treating…” 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.
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 15 — 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.
Case 20 — Lume comparison: keep exposure and charging conditions consistent
Summary draft for “Lume comparison: keep exposure and charging conditions consistent”: the answer addresses “Treat the comparison…”; the related point is “Repeat with equal light source, charging duration, elapsed time and camera…”. 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 36 — What a water-resistance claim does and does not establish
Clarification for “What a water-resistance claim does and does not establish”: the point beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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 8 — 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.
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Document when it stops, winding behaviour, recent impacts 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.
Summary draft for “Lug-to-lug and end-link overhang in wrist photographs”: the answer addresses “Record lug-to-lug and the effective span…”; the related point is “Use a similar camera distance and neutral wrist position; photographs support…”. 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 43 — Reading a timegrapher recording without losing the context · source wording exercise
Clarification for “Reading a timegrapher recording without losing the context”: the point beginning “A single number cannot establish service condition, movement identity…” 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.
