Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.

Case 32 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
The core trade-off is scratch resistance versus shatter resistance. Sapphire is very hard to scratch but can chip or crack from a sharp impact on an edge. Acrylic scratches easily but flexes, rarely shatters, and light scratches can be polished out at home. Mineral glass sits in between and is often the cheapest to replace.
Case 20 — Clasp photographs: what to request before judging alignment
Correction note for “Clasp photographs: what to request before judging alignment”: retain the wording beginning “Request open and closed views from both sides,…” 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 19 — A maintenance log that remains useful after a sale
Correction note for “A maintenance log that remains useful after a sale”: retain the wording beginning “Keep the date, work performed, provider invoice reference…” 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.
Clarification for “Strap dimensions: lug width, taper, thickness and spring bar diameter explained”: the point beginning “Lug width is the essential one: the inside distance between…” 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.
Clarification for “Case finishing: distinguish a reflection from a surface mark”: the point beginning “Ask for photographs with the light moved 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.
Case 1 — Date window centring: compare the same date at the same angle
Method note for “Date window centring: compare the same date at the same angle”: use “Use the same numeral, camera axis…” 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 49 — Movement identification: the limits of a rotor photograph · source wording exercise
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Ask a qualified watchmaker to inspect it if identification matters for…” as the discussion anchor; no new event or result is supplied.

Correction note for “Beginner glossary Q&A: complication, caliber, jewel count, power reserve”: retain the wording beginning “Caliber is the movement's model designation,…” 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 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.
Case 21 — Comparing versions without mixing case sizes
Summary draft for “Comparing versions without mixing case sizes”: the answer addresses “Match reference, dimensions and…”; the related point is “List confirmed differences separately from seller descriptions and date the comparison…”. 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 10 — Lug-to-lug and end-link overhang in wrist photographs
A wide-angle wrist photo exaggerates the nearest edge of the case. How can two watches be compared fairly?

Case 29 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Clarifying question: what does daily wear mean for you? Desk work, manual labour or sports change the answer. For desk use, sapphire's scratch resistance is the main benefit. For work with frequent knocks, a slightly domed acrylic that you can polish may last longer in practice, despite the scratches.
Clarification for “First QC request: the minimum useful information”: the point beginning “State the model configuration, the specific concern 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.
Case 33 — Disputed observation: is this dial colour shift real or just lighting?
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?
