Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.

Record lug-to-lug and the effective span including rigid end links. Use a similar camera distance and neutral wrist position; photographs support fit discussion but do not replace measurements.
Case 26 — 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.
Correction note for “Model comparison: dive bezel action and alignment, how to compare fairly”: retain the wording beginning “Separate three properties: click count (60 or 120 positions), feel (how…” 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 46 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
Reader check for “Shipping timeline: separate dispatch, handover and scan events”: distinguish the discussion point “Ask the sender or carrier for clarification; missing scans alone…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: source wording. Retain the source wording beside any paraphrase.
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
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 35 — Model comparison: dive bezel action and alignment, how to compare fairly
On alignment, a clarifying point: is the misalignment visible straight on, or only from an angle? Parallax on a raised bezel can make a perfectly aligned pip look half a click off when viewed slightly from the side. Photograph straight above the dial before calling it misaligned.
Record wrist circumference, removable links and the clasp adjustment range in millimetres. Request the closed bracelet circumference rather than inferring it from marketing dimensions.
Case 27 — Comparing dial colour under different lighting
Summary draft for “Comparing dial colour under different lighting”: the answer addresses “State the lighting and…”; the related point is “Compare controlled images where available and avoid calling a…”. 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 27 — Magnetism and rate: record evidence before naming a cause
Limit of the answer in “Magnetism and rate: record evidence before naming a cause”: “Record the change and the circumstances without treating…” 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 32 — Comparing dial colour under different lighting
Summary draft for “Comparing dial colour under different lighting”: the answer addresses “State the lighting and…”; the related point is “Compare controlled images where available and avoid calling a…”. 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.
Lug width is the essential one: the inside distance between the lugs where the strap fits. Measure with a ruler marked in millimetres, ideally reading it under magnification. Most watches use even numbers (18, 20, 22mm), but odd widths exist. If you measure 19 or 21, measure again and check the manufacturer spec before ordering.
Case 37 — Strap compatibility: width is only the first measurement · source wording exercise
Summary draft for “Strap compatibility: width is only the first measurement”: the answer addresses “Avoid forcing an assembly that does not fit and…”; the related point is “Measure the lug opening and document bar diameter,…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
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.
