Reader check for “Comparing versions without mixing case sizes”: distinguish the discussion point “Match reference, dimensions and…” from its proposed application. The thread offers a way to reason about the question, without adding a personal experience or a newly observed outcome. Review focus: scope. Keep the stated question separate from any broader claim.
Case 31 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Compare the observed rate with the exact caliber and cased-watch specification, if available. An example such as -8 seconds per day cannot be declared acceptable solely from its price category.
Case 19 — QC checklist: prioritise observable faults over pixel hunting
Summary draft for “QC checklist: prioritise observable faults over pixel hunting”: the answer addresses “Start with function, legibility, assembly and…”; the related point is “Explain what the full-size image shows, what the crop adds and…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: scope. Keep the stated question separate from any broader claim.
Case 18 — Magnetism and rate: record evidence before naming a cause
Summary draft for “Magnetism and rate: record evidence before naming a cause”: the answer addresses “Record the change and the circumstances without treating…”; the related point is “A competent watchmaker can test and diagnose it; random adjustment…”.

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 48 — What a water-resistance claim does and does not establish · source wording exercise
Clarification for “What a water-resistance claim does and does not establish”: the point beginning “A photograph or a caseback engraving is not…” 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.
Power reserve is how long the watch runs from full wind until it stops. It matters if you rotate watches: a 38-hour reserve may stop over a weekend off the wrist, while 70-plus hours may not. One clarifying point is that rate stability often gets worse near the end of the reserve, so the full figure is not all precision-grade running time.
Case 21 — Comparing versions without mixing case sizes
Two purported versions differ in case diameter and bracelet. How can the comparison avoid attributing every difference to a revision?
Exercise RWF-17684/21: address this question within its stated limits.
Case 9 — Service enquiry: information a watchmaker can use
Document when it stops, winding behaviour, recent impacts and the positions in which it happens. Be honest about the watch and request an assessment before approving work or ordering parts.
Case 28 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
One method that often helps without any service is using overnight resting position to cancel daily drift. Many watches gain in some positions and lose in others. If yours loses on the wrist, try leaving it crown up or dial up overnight and log the result for a few nights. Some people get close to zero this way.
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “No single lighting setup settles…” belongs to the question as written.

Case 32 — 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.
Start with how you measured it. Comparing against a phone clock once a day for a week, at the same time, and noting the offset is reliable enough. One 24-hour reading isn't, because rate depends on wrist time, position overnight and state of wind. Average across several days before deciding anything.
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Compare two independently aligned images before drawing a conclusion; an overlay…” 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.
