Case 38 — Maintenance question: how do I tell if an automatic actually needs service? · source wording exercise
Clarification for “Maintenance question: how do I tell if an automatic actually needs service?”: the point beginning “Useful signs, in rough order of seriousness: power reserve noticeably shorter…” 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: source wording. Retain the source wording beside any paraphrase.
Case 166 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem · uncertainty exercise
Correction note for “Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem”: retain the wording beginning “Measure the actual change at each setting rather than assuming 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. Leave the unresolved part visible instead of supplying a result.
Case 38 — 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.
Method note for “Comparing dial colour under different lighting”: use “State the lighting and…” 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.
Use a correction row with date, old value, revised value and evidence. A worked example could change a lug-width entry from 20 to 22 mm; do not present that example as a correction to a real model.
Case 2 — 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?
Exercise RWF-20816/2: address this question within its stated limits.
Case 29 — 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.
Caliber is the movement's model designation, like a part number. Two watches from different brands can share the same caliber family with different finishing or regulation. On a spec sheet it tells you what's inside and roughly what service parts are available. It doesn't tell you how well that particular example was adjusted.
Case 17 — Comparing versions without mixing case sizes
Method note for “Comparing versions without mixing case sizes”: use “Match reference, dimensions and…” 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 27 — Service enquiry: information a watchmaker can use
A service question only says that the watch stops occasionally. Which observations make an initial enquiry more useful?
Exercise RWF-16049/27: address this question within its stated limits.
Lume photos are close to useless for comparison unless exposure is fixed. Phones raise exposure automatically in the dark, so a dim watch can look as bright as a strong one. For a fair photo comparison: same charge method, same delay after charging, manual exposure, and both watches in the same frame.
Method note for “Lume comparison: keep exposure and charging conditions consistent”: use “Treat the comparison…” 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 34 — What a water-resistance claim does and does not establish
Limit of the answer in “What a water-resistance claim does and does not establish”: “Ask a qualified watchmaker about a suitable test for that individual…” 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.
Clarification for “Comparing dial colour under different lighting”: the point beginning “State the lighting 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.
Thickness matters more than people expect. Straps around 4 to 5mm at the lugs can hit the case or stop the strap folding down on watches with short lugs or tight lug-to-case clearance. Do you know whether your watch has drilled lugs or a tight gap between strap and case? That tells you how much thickness is safe.
