Case 46 — QC photographs: perspective or a genuinely tilted index? · source wording exercise
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Compare two independently aligned images before drawing a conclusion; an overlay…” 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. Retain the source wording beside any paraphrase.
Case 175 — Bracelet fit: measuring the usable clasp adjustment · uncertainty exercise
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. Leave the unresolved part visible instead of supplying a result.
Case 47 — What a water-resistance claim does and does not establish · source wording exercise
Method note for “What a water-resistance claim does and does not establish”: use “A photograph or a caseback engraving is not…” 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. Retain the source wording beside any paraphrase.
Ask a qualified watchmaker about a suitable test for that individual case and record the test date and method. A photograph or a caseback engraving is not proof of water resistance.
Case 10 — What a water-resistance claim does and does not establish
Correction note for “What a water-resistance claim does and does not establish”: retain the wording beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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.
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.
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.
Case 26 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
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.
Case 35 — Case finishing: distinguish a reflection from a surface mark
Correction note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “Ask for photographs with the light moved and…” 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 “Lume comparison: keep exposure and charging conditions consistent”: retain the wording beginning “Repeat with equal light source, charging duration, elapsed time and camera…” 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.
Clarification for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: the point beginning “Add lug-to-lug, thickness and lug width…” 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.
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.
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.
Treat the comparison as inconclusive. Repeat with equal light source, charging duration, elapsed time and camera settings; disclose conditions rather than assigning an unsupported quality score.
Case 14 — QC checklist: prioritise observable faults over pixel hunting
Clarification for “QC checklist: prioritise observable faults over pixel hunting”: the point beginning “Start with function, legibility, assembly 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.
