Domed crystals of any material add distortion at the edges, which some people like and others find hard to read at angles. Box-shaped or high-domed crystals also add thickness. If you're comparing two otherwise similar watches, check total thickness against crystal profile before assuming the case itself is thicker.

Clarification for “Movement identification: the limits of a rotor photograph”: the point beginning “Describe visible bridge shapes and markings separately…” 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 23 — Case finishing: distinguish a reflection from a surface mark
Method note for “Case finishing: distinguish a reflection from a surface mark”: use “Ask for photographs with the light moved 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 42 — Service enquiry: information a watchmaker can use · source wording exercise
Limit of the answer in “Service enquiry: information a watchmaker can use”: “Be honest about the watch and request an assessment…” 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: source wording. Retain the source wording beside any paraphrase.
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
Correction note for “Clasp photographs: what to request before judging alignment”: retain the wording beginning “Separate cosmetic alignment from whether the clasp engages reliably;…” 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 30 — QC photography: what photos actually help verify a pre-owned listing?
Proposed reusable request list. 1) Straight dial, diffuse light, hands clear of markers. 2) Both case profiles. 3) Lug tops at an angle. 4) Caseback and engravings. 5) Clasp and bracelet end links. 6) Dated note in frame. Optional: timegrapher reading or movement photos. Add or change items with a reason, and I'll keep the list current.
Case 23 — Strap compatibility: width is only the first measurement
Clarification for “Strap compatibility: width is only the first measurement”: the point beginning “Measure the lug opening and document bar diameter,…” 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 23 — Case finishing: distinguish a reflection from a surface mark
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?
Exercise RWF-19445/23: address this question within its stated limits.
Case 28 — Strap compatibility: width is only the first measurement
Clarification for “Strap compatibility: width is only the first measurement”: the point beginning “Measure the lug opening and document bar diameter,…” 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 “A maintenance log that remains useful after a sale”: use “Keep the date, work performed, provider invoice reference…” 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 33 — What a water-resistance claim does and does not establish
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.
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 27 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
A notation like 20/16 means 20mm at the lugs, tapering to 16mm at the buckle. Taper affects look and comfort more than fit. A strong taper suits smaller and dressier cases, a straight strap suits sport watches. Your buckle or clasp also has to match the narrow end, so check that if you want to reuse an existing buckle.
Case 13 — 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.
