Case 33 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
A correction worth making: 'sapphire = premium, mineral = cheap' oversimplifies it. A well-fitted mineral crystal on a modest watch can be perfectly suitable, and replacing a cracked sapphire is usually more expensive. Material is one factor among several, alongside fit, gasket quality and coating.
Clarification for “Lume comparison: keep exposure and charging conditions consistent”: the point beginning “Repeat with equal light source, charging duration, elapsed time and camera…” 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 19 — Disputed observation: is this dial colour shift real or just lighting?
Clarifying question: does anyone in the thread have access to both versions at once? Without simultaneous comparison, every claim either way is weak evidence. If not, the next best option is photos with a grey card in frame and white balance locked or set manually, which at least makes separate photos roughly comparable.
Case 25 — A maintenance log that remains useful after a sale
Which information should a transferable maintenance log retain while protecting the owner’s identity?

Case 36 — Date window centring: compare the same date at the same angle
Summary draft for “Date window centring: compare the same date at the same angle”: the answer addresses “Use the same numeral, camera axis…”; the related point is “Keep the uncropped originals alongside the detail crops and distinguish…”. 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.
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.
Case 7 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
The lift angle must match the movement specification for the amplitude reading to be meaningful. If it is unknown, label amplitude as provisional instead of accepting the instrument default.
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Distinguish label creation from physical acceptance and retain dated…” 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 40 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve · source wording exercise
New here and reading spec sheets for the first time. Four terms keep tripping me up: complication, caliber, jewel count and power reserve. Short definitions would help, and so would a note on which ones actually matter when comparing two everyday watches.
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Two watches from different brands can share the same caliber…” as the discussion anchor; no new event or result is supplied.

Case 22 — QC photography: what photos actually help verify a pre-owned listing?
Ask for profile shots of both case sides and a lug-top shot at an angle. Polishing shows as rounded edges, softened bevels or lug holes that look shallower than they should. Compare against a known-good reference image of the same model, not memory. A side-by-side tells you far more than a description.
Case 1 — Movement identification: the limits of a rotor photograph
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Describe visible bridge shapes and markings separately…”; the related point is “Ask a qualified watchmaker to inspect it if identification matters for…”. 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 19 — Bracelet fit: measuring the usable clasp adjustment
Correction note for “Bracelet fit: measuring the usable clasp adjustment”: retain the wording beginning “Record wrist circumference, removable links and the clasp…” 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.
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 23 — 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?
Exercise RWF-15754/23: address this question within its stated limits.
Add lug-to-lug, thickness and lug width as separate rows. Diameter alone tells you little about wearability. Two cases 2mm apart in diameter can be within 1mm of each other lug to lug, and that number decides whether the watch overhangs a small wrist. Also give the source for each figure: manufacturer sheet, caliper measurement, or catalogue listing.
