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 26 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
A correction to a common belief: an automatic doesn't need to match a quartz watch to be healthy. Consistency matters more than the absolute figure. A watch that's reliably -8 every day is easy to live with, since you correct it once a week. One that swings from +10 to -15 is the real concern.
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 32 — What a water-resistance claim does and does not establish
Summary draft for “What a water-resistance claim does and does not establish”: the answer addresses “Ask a qualified watchmaker about a suitable test for that individual…”; the related point is “A photograph or a caseback engraving is not…”. 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 4 — Lug-to-lug and end-link overhang in wrist photographs
Limit of the answer in “Lug-to-lug and end-link overhang in wrist photographs”: “Record lug-to-lug and the effective span…” is an excerpt from the discussion, not an independent verification. A reader needs the relevant original material before treating an interpretation as established. Review focus: scope. Keep the stated question separate from any broader claim.
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
Summary so far. Rows: diameter, lug-to-lug, thickness (method stated), lug width, crystal type, water resistance (as specified), movement family, production period. Each row has a source tag. Corrections go in the dated log with old and new values. If nobody objects, that's the template, and later posts should give evidence rather than restate opinions.
Clarification for “Crown operation: when a forum cannot diagnose the resistance”: the point beginning “Describe whether resistance occurs during winding or setting 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.
Method note for “Crystal reflections: why a dark patch is not a coating test”: use “No single lighting setup settles…” 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 39 — QC photographs: perspective or a genuinely tilted index? · source wording exercise
Clarification for “QC photographs: perspective or a genuinely tilted index?”: the point beginning “Compare two independently aligned images before drawing a conclusion; an overlay…” 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 17 — Lume comparison: keep exposure and charging conditions consistent
Clarification for “Lume comparison: keep exposure and charging conditions consistent”: the point beginning “Treat the comparison…” 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 29 — Model comparison: dive bezel action and alignment, how to compare fairly
Separate preference from a potential functional problem. Inconsistent engagement, slipping or uncertain alignment should be documented and checked against the design’s specification by a competent watchmaker; do not invent a universal defect threshold.
State the lighting and white-balance limitations. Compare controlled images where available and avoid calling a colour defect from differently processed photographs.
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.
Summary draft for “Model comparison: dive bezel action and alignment, how to compare fairly”: the answer addresses “Separate three properties: click count (60 or 120 positions), feel (how…”; the related point is “Crisp vs mushy is mostly about…”. 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.
