Case 43 — Movement identification: the limits of a rotor photograph · source wording exercise
Correction note for “Movement identification: the limits of a rotor photograph”: retain the wording beginning “Ask a qualified watchmaker to inspect it if identification matters for…” 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 35 — Service enquiry: information a watchmaker can use
Limit of the answer in “Service enquiry: information a watchmaker can use”: “Document when it stops, winding behaviour, recent impacts and…” 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 39 — Bracelet fit: measuring the usable clasp adjustment · source wording exercise
Reader check for “Bracelet fit: measuring the usable clasp adjustment”: distinguish the discussion point “Request the closed bracelet circumference rather than inferring…” 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 47 — Comparing versions without mixing case sizes · source wording exercise
Reader check for “Comparing versions without mixing case sizes”: distinguish the discussion point “List confirmed differences separately from seller descriptions and date the comparison…” 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.
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Case 230 — Crystal reflections: why a dark patch is not a coating test · indexing exercise
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. It should not be read as a report that a new check, purchase or experiment has been completed. Review focus: indexing. Make the reasoning findable without reducing it to a trust score.
Case 16 — Crystal reflections: why a dark patch is not a coating test
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. 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.
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 2 — Lug-to-lug and end-link overhang in wrist photographs
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Record lug-to-lug and the effective span…” 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.
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.
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.
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.
Case 32 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
Domed crystals of any material add distortion at the edges, which some people like and others find hard to read at angles. Box-shaped or high-domed crystals also add thickness. If you're comparing two otherwise similar watches, check total thickness against crystal profile before assuming the case itself is thicker.
Case 34 — QC photography: what photos actually help verify a pre-owned listing?
Ask for a straight-on dial photo with diffuse light and no flash, the full dial in frame, and the hands placed away from the indices (10:10 isn't ideal, because it covers the upper markers). Flash flattens printing and hides lume condition. Diffuse light shows print edges, alignment and any spotting.
Case 4 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
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?
Exercise RWF-15056/4: address this question within its stated limits.
