Case 1 — 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 1 — 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.
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.
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Case 3 — 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?

Case 38 — Comparing dial colour under different lighting · source wording exercise
One image was taken beside a window and the other under a warm lamp. How should a colour comparison be qualified?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Compare controlled images where available and avoid calling a…” as the discussion anchor; no new event or result is supplied.

Case 17 — Model comparison: dive bezel action and alignment, how to compare fairly
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.
Clarifying question for the thread: is the goal to check authenticity, condition, or both? For condition, the request list above is enough. For authenticity, you also need caseback, serial or reference engravings, and ideally movement photos. Movement photos usually require opening the watch, which a seller may reasonably refuse without a watchmaker present.
Case 42 — Disputed observation: is this dial colour shift real or just lighting? · source wording exercise
Correction note for “Disputed observation: is this dial colour shift real or just lighting?”: retain the wording beginning “Two photos of the same dial under different light can…” 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.
Case 17 — Maintenance question: how do I tell if an automatic actually needs service?
The calendar interval is a conservative default, not a rule. Useful signs, in rough order of seriousness: power reserve noticeably shorter than spec from full wind, rate drifting outside its usual range, the watch stopping on the wrist, gritty or rough winding, and the date changing slowly or late.
