Case 10 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Document spring-bar diameter, end-tip fit and the strap’s clearance using appropriate measuring tools. If dimensions or compatibility are uncertain, ask a watchmaker rather than forcing a bar or substituting an unsuitable part.
Case 14 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
On anti-reflective coatings: inner-surface AR cuts glare without wear concerns. Outer-surface AR improves legibility further but can scuff over time, and the scuffs show up as hazy patches in certain light. When comparing two watches, check which surfaces are coated. Spec sheets often just say 'AR coated' without saying where.
Case 55 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me? · source wording exercise
Method note for “Timegrapher reading context: what do rate, amplitude and beat error actually tell me?”: use “Without those fields, the rate, amplitude and beat-error values lack…” 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.
Method note for “Clasp photographs: what to request before judging alignment”: use “Request open and closed views from both sides,…” 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.
Clarifying question: how are you charging it? A few seconds under a warm indoor bulb gives a much weaker charge than daylight or a UV source. Many 'weak lume' reports turn out to be undercharging. Try a consistent charge, such as 30 seconds under a phone flashlight at a fixed distance, before judging.
Ask for profile shots of both case sides and a lug-top shot at an angle. Polishing shows as rounded edges, softened bevels or lug holes that look shallower than they should. Compare against a known-good reference image of the same model, not memory. A side-by-side tells you far more than a description.
Method note for “Crystal reflections: why a dark patch is not a coating test”: use “Compare multiple controlled angles and describe the visible observation without asserting…” 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.
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Use the same numeral, camera axis…” 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.
Ask for profile shots of both case sides and a lug-top shot at an angle. Polishing shows as rounded edges, softened bevels or lug holes that look shallower than they should. Compare against a known-good reference image of the same model, not memory. A side-by-side tells you far more than a description.
State the model configuration, the specific concern and links to clear redacted images. Include complete instrument settings where relevant and say explicitly what evidence is missing.
Case 13 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
Case 16 — Movement identification: the limits of a rotor photograph
Method note for “Movement identification: the limits of a rotor photograph”: use “Describe visible bridge shapes and markings separately…” 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 47 — Crystal reflections: why a dark patch is not a coating test · source wording exercise
Correction note for “Crystal reflections: why a dark patch is not a coating test”: retain the wording beginning “Compare multiple controlled angles and describe the visible observation without asserting…” 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.
Request open and closed views from both sides, with the watch supported safely. Separate cosmetic alignment from whether the clasp engages reliably; functional concerns need hands-on inspection.
Case 16 — 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.
