Case 20 — 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.
Case 34 — 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 109 — Movement identification: the limits of a rotor photograph · documentation exercise
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Review focus: documentation. Distinguish an original record from a proposed record format. Use the original answer fragment “Ask a qualified watchmaker to inspect it if identification matters for…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-28278/109: address this question within its stated limits.
Correction note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “A mark should be assessed across multiple views; aggressive polishing…” 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 8 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
My bracelet is either slightly too tight or slightly loose with any link combination. The clasp has three micro-adjust holes, and there are no half-links. What are the options before I give up and go to a strap?
Exercise RWF-25919/8: address this question within its stated limits.
Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “Record the change and the circumstances without treating…” 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.
Jewel count describes bearings used in a movement design; it is not a quality ranking. Compare the documented movement architecture and service support rather than assuming a higher count makes one watch better.
Case 25 — Bracelet fit: measuring the usable clasp adjustment
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 26 — Comparing dial colour under different lighting
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.
Case 24 — Crystal reflections: why a dark patch is not a coating test
No single lighting setup settles that question. Compare multiple controlled angles and describe the visible observation without asserting material specifications that have not been verified.
Case 3 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Clarifying question: what does daily wear mean for you? Desk work, manual labour or sports change the answer. For desk use, sapphire's scratch resistance is the main benefit. For work with frequent knocks, a slightly domed acrylic that you can polish may last longer in practice, despite the scratches.
Case 51 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log · source wording exercise
Correction note for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: retain the wording beginning “Diameter alone tells you little…” 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.
Case 11 — 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.
The difficulty is that phone cameras adjust white balance automatically, and blue dials are especially sensitive. Two photos of the same dial under different light can easily look like a 'batch difference'. Any comparison needs both dials in the same frame, under the same light, ideally next to a neutral grey or white reference card.
A stated water-resistance rating does not establish the present condition of an individual watch. Separate the manufacturer specification from a dated inspection or test of the particular example.
