No single lighting setup settles that question. Compare multiple controlled angles and describe the visible observation without asserting material specifications that have not been verified.

Case 14 — Forum comparison archive: link the evidence and the correction
A comparison has been corrected after a new photograph arrived. How should the original thread remain useful?
Exercise RWF-30406/14: address this question within its stated limits.
Case 18 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
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.
Reader check for “Comparing versions without mixing case sizes”: distinguish the discussion point “Match reference, dimensions and…” 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.
Case 8 — A maintenance log that remains useful after a sale
Clarification for “A maintenance log that remains useful after a sale”: the point beginning “Keep the date, work performed, provider invoice reference…” 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.
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.
Clarification for “QC photography: what photos actually help verify a pre-owned listing?”: the point beginning “Ask for a straight-on dial photo with diffuse light and no…” 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 14 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
A notation like 20/16 means 20mm at the lugs, tapering to 16mm at the buckle. Taper affects look and comfort more than fit. A strong taper suits smaller and dressier cases, a straight strap suits sport watches. Your buckle or clasp also has to match the narrow end, so check that if you want to reuse an existing buckle.
Case 4 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
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 8 — Movement identification: the limits of a rotor photograph
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
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.
Start with how you measured it. Comparing against a phone clock once a day for a week, at the same time, and noting the offset is reliable enough. One 24-hour reading isn't, because rate depends on wrist time, position overnight and state of wind. Average across several days before deciding anything.
Case 30 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Summary. Pick sapphire for scratch resistance in low-impact use, acrylic for impact tolerance and easy polishing, and mineral as a low-cost middle option. Prefer inner-surface AR if you're worried about wear. Look at crystal profile when comparing thickness. Choose by how you'll use the watch, not by the material label.

Case 16 — 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.
