Case 9 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
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 19 — Crystal reflections: why a dark patch is not a coating test
Method note for “Crystal reflections: why a dark patch is not a coating test”: use “No single lighting setup settles…” 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.
The calendar interval is a conservative default, not a rule. Useful signs, in rough order of seriousness: power reserve noticeably shorter than spec from full wind, rate drifting outside its usual range, the watch stopping on the wrist, gritty or rough winding, and the date changing slowly or late.
Case 1 — Shipping timeline: separate dispatch, handover and scan events
Distinguish label creation from physical acceptance and retain dated event text with personal details removed. Ask the sender or carrier for clarification; missing scans alone do not establish loss or seizure.
Case 25 — 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-26823/25: address this question within its stated limits.
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.
Method note for “What a water-resistance claim does and does not establish”: use “Ask a qualified watchmaker about a suitable test for that individual…” 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 23 — First QC request: the minimum useful information
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.
On alignment, a clarifying point: is the misalignment visible straight on, or only from an angle? Parallax on a raised bezel can make a perfectly aligned pip look half a click off when viewed slightly from the side. Photograph straight above the dial before calling it misaligned.
Case 20 — Movement identification: the limits of a rotor photograph
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Exercise RWF-19403/20: address this question within its stated limits.
Case 34 — Lug-to-lug and end-link overhang in wrist photographs
Limit of the answer in “Lug-to-lug and end-link overhang in wrist photographs”: “Record lug-to-lug and the effective span…” 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.
Case 8 — QC photographs: perspective or a genuinely tilted index?
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Request a level straight-on image with the hands…” 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 15 — 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-15832/15: address this question within its stated limits.
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 26 — A maintenance log that remains useful after a sale
Limit of the answer in “A maintenance log that remains useful after a sale”: “Keep the date, work performed, provider invoice reference…” 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.
