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.

Clarification for “Movement identification: the limits of a rotor photograph”: the point beginning “Describe visible bridge shapes and markings separately…” 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 15 — Reading a timegrapher recording without losing the context
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Domed crystals of any material add distortion at the edges, which some people like and others find hard to read at angles. Box-shaped or high-domed crystals also add thickness. If you're comparing two otherwise similar watches, check total thickness against crystal profile before assuming the case itself is thicker.
Case 25 — 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-20267/25: address this question within its stated limits.
Case 2 — What a water-resistance claim does and does not establish
Method note for “What a water-resistance claim does and does not establish”: use “Ask a qualified watchmaker about a suitable test for that individual…” 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 20 — 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-18075/20: address this question within its stated limits.
Case 13 — 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 6 — First QC request: the minimum useful information
Summary draft for “First QC request: the minimum useful information”: the answer addresses “State the model configuration, the specific concern and…”; the related point is “Include complete instrument settings where relevant and say…”. 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 17 — 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-14475/17: address this question within its stated limits.
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 4 — Date window centring: compare the same date at the same angle
Summary draft for “Date window centring: compare the same date at the same angle”: the answer addresses “Use the same numeral, camera axis…”; the related point is “Keep the uncropped originals alongside the detail crops and distinguish…”. 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 — Model comparison: dive bezel action and alignment, how to compare fairly
Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.
Case 83 — QC photographs: perspective or a genuinely tilted index? · comparison exercise
Clarification for “QC photographs: perspective or a genuinely tilted index?”: the point beginning “Request a level straight-on image with the hands…” 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: comparison. Make the basis of a comparison explicit before interpreting it.
Case 51 — Movement identification: the limits of a rotor photograph · source wording exercise
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Ask a qualified watchmaker to inspect it if identification matters for…” as the discussion anchor; no new event or result is supplied.
