Case 25 — QC photography: what photos actually help verify a pre-owned listing?
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 39 — Reading a timegrapher recording without losing the context · source wording exercise
The supplied screen shows a rate but does not identify the lift angle, position or winding state. Which observations should accompany the recording?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “A single number cannot establish service condition, movement identity…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-30288/39: address this question within its stated limits.
Case 28 — 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.
Case 29 — Maintenance question: how do I tell if an automatic actually needs service?
Clarifying question first: do you have a baseline? If you've never recorded the watch's rate or power reserve, 'drifting' is hard to judge. Start a simple log now with daily offset against a reference time for a week, and the hours it runs from full wind. Once you have that, later changes mean something.
Case 35 — Date window centring: compare the same date at the same angle
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 26 — 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?

Case 216 — Lug-to-lug and end-link overhang in wrist photographs · correction exercise
Correction note for “Lug-to-lug and end-link overhang in wrist photographs”: retain the wording beginning “Use a similar camera distance and neutral wrist position; photographs support…” 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. Preserve the old wording if a later source changes the interpretation.
Case 2 — Lug-to-lug and end-link overhang in wrist photographs
Correction note for “Lug-to-lug and end-link overhang in wrist photographs”: retain the wording beginning “Record lug-to-lug and the effective span…” 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 30 — Strap compatibility: width is only the first measurement
Method note for “Strap compatibility: width is only the first measurement”: use “Measure the lug opening and document bar diameter,…” 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.
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Method note for “Bracelet fit: measuring the usable clasp adjustment”: use “Record wrist circumference, removable links and the clasp…” 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.
Summary order of importance. 1) Lug width, measured between the lugs. 2) Lug-end thickness against clearance. 3) Spring bar diameter. 4) Taper and buckle width. 5) Length, which is usually given as long side / short side in mm and should be compared with a strap that already fits you.
Case 38 — 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.
Case 19 — 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 20 — Crown operation: when a forum cannot diagnose the resistance
Limit of the answer in “Crown operation: when a forum cannot diagnose the resistance”: “Describe whether resistance occurs during winding or setting 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.
