Case 28 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Wrist size changes during the day and with temperature, sometimes by several millimetres. A fit that feels tight in the afternoon may be right in the morning. Before buying parts, check the fit at different times. You may find the 'too tight' setting is only a problem a few hours a day.
Compare the observed rate with the exact caliber and cased-watch specification, if available. An example such as -8 seconds per day cannot be declared acceptable solely from its price category.
Case 39 — Crystal reflections: why a dark patch is not a coating test · source wording exercise
A dark area appears at an oblique angle in a single photograph. Does that establish a coating difference?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Compare multiple controlled angles and describe the visible observation without asserting…” as the discussion anchor; no new event or result is supplied.

Case 20 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
First, a clarifying question: how many links are on each side of the clasp right now? Fit often improves by moving one link from the 6 o'clock side to the 12 o'clock side, or the reverse. That doesn't change length, but it shifts where the clasp sits under the wrist, and a centred clasp feels less tight.
Limit of the answer in “Disputed observation: is this dial colour shift real or just lighting?”: “The difficulty is that phone cameras adjust white balance automatically,…” 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.
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.
Clarification for “What a water-resistance claim does and does not establish”: the point beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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 32 — Model comparison: dive bezel action and alignment, how to compare fairly
People keep comparing the bezels on two similar dive-style watches. One is called crisp, the other mushy, and alignment complaints come up for both. What would a fair comparison look like, and what is actually a defect versus a preference?

Case 13 — Forum comparison archive: link the evidence and the correction
Summary draft for “Forum comparison archive: link the evidence and the correction”: the answer addresses “Add a dated correction near the original conclusion…”; the related point is “Preserve the reasoning trail instead of silently replacing an…”. 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.
