Case 48 — Comparing dial colour under different lighting · source wording exercise
Correction note for “Comparing dial colour under different lighting”: retain the wording beginning “Compare controlled images where available and avoid calling a…” 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.
Limit of the answer in “Case finishing: distinguish a reflection from a surface mark”: “Ask for photographs with the light moved and…” 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.
Case 12 — Comparing versions without mixing case sizes
Method note for “Comparing versions without mixing case sizes”: use “Match reference, dimensions and…” 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.
Document when it stops, winding behaviour, recent impacts and the positions in which it happens. Be honest about the watch and request an assessment before approving work or ordering parts.
Limit of the answer in “Date window centring: compare the same date at the same angle”: “Use the same numeral, camera axis…” 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.
Case 96 — Disputed observation: is this dial colour shift real or just lighting? · comparison 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: comparison. Make the basis of a comparison explicit before interpreting it. Use the original answer fragment “Any comparison needs both dials in the same frame, under the…” as the discussion anchor; no new event or result is supplied.

Case 19 — Case finishing: distinguish a reflection from a surface mark
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?

Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Ask a qualified watchmaker to inspect it if identification matters for…”; the related point is “Describe visible bridge shapes and markings separately…”. 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 27 — 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 24 — Model comparison: dive bezel action and alignment, how to compare fairly
Separate three properties: click count (60 or 120 positions), feel (how firm each click is, and whether there's back-play), and alignment (whether the pip lines up with the 12 o'clock marker at rest). Crisp vs mushy is mostly about feel and back-play. Alignment can be measured, so treat it separately.
Case 10 — 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.
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 14 — 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.
A bright initial glow followed by a steep drop is normal for photoluminescent pigments. Afterglow fades fastest in the first minutes and then settles to a dim, long-lasting level that dark-adapted eyes can still read. The real question is whether it's readable after an hour in darkness, not how it looks right after charging.
Case 3 — Date window centring: compare the same date at the same angle
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
