Case 4 — 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 40 — Disputed observation: is this dial colour shift real or just lighting? · source wording exercise
Several posts claim the newer batch of a particular blue-dial model looks more purple than the earlier batch. Others say it's purely photography and white balance. Can we settle this with evidence instead of arguing from different photos?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Two photos of the same dial under different light can…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-28409/40: address this question within its stated limits.
Micro-adjust spacing varies by clasp. Measure the actual change at each setting rather than assuming a standard number of millimetres; compare the usable range with the link length.
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.
Case 44 — Movement identification: the limits of a rotor photograph · source wording exercise
Correction note for “Movement identification: the limits of a rotor photograph”: retain the wording beginning “Ask a qualified watchmaker to inspect it if identification matters for…” 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.
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.
Record wrist circumference, removable links and the clasp adjustment range in millimetres. Request the closed bracelet circumference rather than inferring it from marketing dimensions.
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “No single lighting setup settles…” 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 5 — 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.
Method note for “Lug-to-lug and end-link overhang in wrist photographs”: use “Record lug-to-lug and the effective span…” 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 22 — Movement identification: the limits of a rotor photograph
Correction note for “Movement identification: the limits of a rotor photograph”: retain the wording beginning “Describe visible bridge shapes and markings separately…” 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.

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 12 — Comparing dial colour under different lighting
Summary draft for “Comparing dial colour under different lighting”: the answer addresses “State the lighting and…”; the related point is “Compare controlled images where available and avoid calling a…”. 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 33 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Log the rate over several comparable days, identify the correct specification and state the conditions. Stable and changing patterns raise different questions; a watchmaker can assess whether regulation, inspection or no action is appropriate.
