Case 237 — Maintenance question: how do I tell if an automatic actually needs service? · indexing exercise
Common advice says service every five years, but service is expensive and some people run watches much longer. What observable signs actually indicate a mechanical watch needs attention, as opposed to just being due on a calendar?
Review focus: indexing. Make the reasoning findable without reducing it to a trust score. Use the original answer fragment “If the manufacturer provides a suitable procedure, a running-time…” as the discussion anchor; no new event or result is supplied.

Case 23 — 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.
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: scope. Keep the stated question separate from any broader claim.
Case 9 — Case finishing: distinguish a reflection from a surface mark
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.
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 1 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
New here and reading spec sheets for the first time. Four terms keep tripping me up: complication, caliber, jewel count and power reserve. Short definitions would help, and so would a note on which ones actually matter when comparing two everyday watches.

Back-play is the most objective feel measurement. Set the bezel on a click and gently push it the other way without forcing it. Noticeable wobble before it engages means play. A little is common and within normal production, but if one model has visible movement and the other doesn't, that's a real difference you can describe.

Case 41 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic? · source wording exercise
My entry-level automatic loses about 8 seconds a day. The spec sheet lists a tolerance range, but I'm not sure how to read it or whether my measurement is reliable. Is this something to fix or something to live with?

Case 10 — What a water-resistance claim does and does not establish
Summary draft for “What a water-resistance claim does and does not establish”: the answer addresses “Ask a qualified watchmaker about a suitable test for that individual…”; the related point is “A photograph or a caseback engraving is not…”. 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 46 — Lug-to-lug and end-link overhang in wrist photographs · source wording exercise

Case 11 — 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?

Keep the date, work performed, provider invoice reference and test results where available. Redact addresses and payment information; do not invent service events to fill an empty history.
