State the lighting and white-balance limitations. Compare controlled images where available and avoid calling a colour defect from differently processed photographs.

Record the change and the circumstances without treating the suspected cause as established. A competent watchmaker can test and diagnose it; random adjustment is not a substitute for assessment.
Case 40 — Disputed observation: is this dial colour shift real or just lighting? · source wording exercise
Summary draft for “Disputed observation: is this dial colour shift real or just lighting?”: the answer addresses “Two photos of the same dial under different light can…”; the related point is “Any comparison needs both dials in the same frame, under the…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
Reader check for “Magnetism and rate: record evidence before naming a cause”: distinguish the discussion point “Record the change and the circumstances without treating…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: scope. Keep the stated question separate from any broader claim.
Lume photos are close to useless for comparison unless exposure is fixed. Phones raise exposure automatically in the dark, so a dim watch can look as bright as a strong one. For a fair photo comparison: same charge method, same delay after charging, manual exposure, and both watches in the same frame.
Case 4 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Thickness matters more than people expect. Straps around 4 to 5mm at the lugs can hit the case or stop the strap folding down on watches with short lugs or tight lug-to-case clearance. Do you know whether your watch has drilled lugs or a tight gap between strap and case? That tells you how much thickness is safe.
Case 8 — A maintenance log that remains useful after a sale
Which information should a transferable maintenance log retain while protecting the owner’s identity?

Case 5 — Model comparison: dive bezel action and alignment, how to compare fairly
Summary table proposal: click count, back-play (none, slight, noticeable), click consistency around the rotation, and alignment (straight-on photo, offset in fractions of a click). With that, the thread can compare actual properties instead of trading adjectives. Dated corrections welcome below.
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.
Case 46 — Reading a timegrapher recording without losing the context · source wording 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: source wording. Retain the source wording beside any paraphrase. 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.

Correction note for “First QC request: the minimum useful information”: retain the wording beginning “State the model configuration, the specific concern 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.
Summary draft for “Beginner glossary Q&A: complication, caliber, jewel count, power reserve”: the answer addresses “Two watches from different brands can share the same caliber…”; the related point is “On a spec sheet it tells you what's inside and…”. 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.
Treat the comparison as inconclusive. Repeat with equal light source, charging duration, elapsed time and camera settings; disclose conditions rather than assigning an unsupported quality score.
Case 8 — 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 1 — 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?
