Case 4 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Correction to a common shortcut: don't measure lug width on an existing strap. Leather and rubber straps compress or swell, and some are made slightly undersized on purpose. Always measure between the lugs themselves, with the strap removed if possible.
Case 72 — What a water-resistance claim does and does not establish · source wording exercise
Reader check for “What a water-resistance claim does and does not establish”: distinguish the discussion point “A photograph or a caseback engraving is not…” 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: source wording. Retain the source wording beside any paraphrase.
Case 6 — Maintenance question: how do I tell if an automatic actually needs service?
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 257 — Comparing dial colour under different lighting · reader check exercise
Reader check for “Comparing dial colour under different lighting”: distinguish the discussion point “Compare controlled images where available and avoid calling a…” 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: reader check. State what a new reader can and cannot infer from this exercise.
Case 44 — Crown operation: when a forum cannot diagnose the resistance · source wording exercise
Clarification for “Crown operation: when a forum cannot diagnose the resistance”: the point beginning “Stop forcing it and arrange inspection rather than trying…” 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.
Case 30 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
The core trade-off is scratch resistance versus shatter resistance. Sapphire is very hard to scratch but can chip or crack from a sharp impact on an edge. Acrylic scratches easily but flexes, rarely shatters, and light scratches can be polished out at home. Mineral glass sits in between and is often the cheapest to replace.
Case 22 — Shipping timeline: separate dispatch, handover and scan events
A tracking page has no new event after a label was created. How can the timeline be discussed without inventing a carrier explanation?
Exercise RWF-19694/22: address this question within its stated limits.
Record the change and the circumstances without treating the suspected cause as established. A competent watchmaker can test and diagnose it; random adjustment is not a substitute for assessment.
Case 9 — Magnetism and rate: record evidence before naming a cause
Method note for “Magnetism and rate: record evidence before naming a cause”: use “Record the change and the circumstances without treating…” 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 31 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
One more term that will come up is 'hacking', meaning the seconds hand stops when you pull the crown so you can set the time to the second. It's minor, but beginners often assume every automatic has it, and not all do. That rounds out the glossary: caliber means what, complication means extra functions, jewels mean bearings, power reserve means how long it runs, hacking means precise setting.
Case 21 — Forum comparison archive: link the evidence and the correction
Method note for “Forum comparison archive: link the evidence and the correction”: use “Add a dated correction near the original conclusion…” 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 “First QC request: the minimum useful information”: the point beginning “State the model configuration, the specific concern and…” 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 32 — 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-11192/32: address this question within its stated limits.
Case 13 — Clasp photographs: what to request before judging alignment
Clarification for “Clasp photographs: what to request before judging alignment”: the point beginning “Request open and closed views from both sides,…” 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.
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.
