Case 24 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
Amplitude depends on the movement and measurement setup. Compare it with appropriate specifications and a qualified watchmaker’s assessment; a universal pass/fail threshold would be misleading.
Case 37 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Clarification for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: the point beginning “Sapphire is very hard to scratch but can chip or crack…” 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.
Case 25 — Model comparison: dive bezel action and alignment, how to compare fairly
People keep comparing the bezels on two similar dive-style watches. One is called crisp, the other mushy, and alignment complaints come up for both. What would a fair comparison look like, and what is actually a defect versus a preference?

Case 24 — First QC request: the minimum useful information
Method note for “First QC request: the minimum useful information”: use “State the model configuration, the specific concern and…” 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 29 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Use a consistent charge, fixed exposure and several elapsed-time observations. Record readability and the conditions rather than applying an unsupported universal fade-time threshold.
Case 19 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Use a correction row with date, old value, revised value and evidence. A worked example could change a lug-width entry from 20 to 22 mm; do not present that example as a correction to a real model.
Case 210 — Reading a timegrapher recording without losing the context · correction exercise
The supplied screen shows a rate but does not identify the lift angle, position or winding state. Which observations should accompany the recording?
Review focus: correction. Preserve the old wording if a later source changes the interpretation. Use the original answer fragment “A single number cannot establish service condition, movement identity…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-25905/210: address this question within its stated limits.
Case 23 — Reading a timegrapher recording without losing the context
Summary draft for “Reading a timegrapher recording without losing the context”: the answer addresses “Keep the complete recording and ask for the…”; the related point is “A single number cannot establish service condition, movement identity…”. 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 27 — Lug-to-lug and end-link overhang in wrist photographs
Record lug-to-lug and the effective span including rigid end links. Use a similar camera distance and neutral wrist position; photographs support fit discussion but do not replace measurements.
Case 45 — Date window centring: compare the same date at the same angle · source wording exercise
Correction note for “Date window centring: compare the same date at the same angle”: retain the wording beginning “Keep the uncropped originals alongside the detail crops and distinguish…” 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.
Add a dated correction near the original conclusion and link the new evidence. Preserve the reasoning trail instead of silently replacing an uncertain claim with a confident one.
Case 32 — Service enquiry: information a watchmaker can use
A service question only says that the watch stops occasionally. Which observations make an initial enquiry more useful?
Exercise RWF-18708/32: address this question within its stated limits.
Case 12 — Comparing versions without mixing case sizes
Method note for “Comparing versions without mixing case sizes”: use “Match reference, dimensions and…” 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 — 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-16063/14: address this question within its stated limits.
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. Keep the stated question separate from any broader claim.
