Case 24 — 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-30568/24: address this question within its stated limits.
Something to keep apart: sunburst and gradient dials can look like different colours depending on viewing angle, even on the same piece. A shift that appears only at certain angles is a finish effect, not a batch difference. Include a straight-on shot and one tilted shot so readers can tell the two apart.
Case 43 — Case finishing: distinguish a reflection from a surface mark · source wording exercise
Limit of the answer in “Case finishing: distinguish a reflection from a surface mark”: “A mark should be assessed across multiple views; aggressive polishing…” 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: source wording. Retain the source wording beside any paraphrase.
Case 117 — Shipping timeline: separate dispatch, handover and scan events · documentation exercise
Clarification for “Shipping timeline: separate dispatch, handover and scan events”: the point beginning “Ask the sender or carrier for clarification; missing scans alone…” 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: documentation. Distinguish an original record from a proposed record format.
Case 19 — 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-27693/19: address this question within its stated limits.
Case 14 — 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-26582/14: address this question within its stated limits.
Correction note for “Comparing dial colour under different lighting”: retain the wording beginning “Compare controlled images where available and avoid calling a…” 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. Keep the stated question separate from any broader claim.
Start with function, legibility, assembly and clear visible damage. Explain what the full-size image shows, what the crop adds and what remains uncertain; do not turn an overlay into an automatic verdict.
Case 27 — First QC request: the minimum useful information
What should an initial QC request include so replies can address the actual question?
Exercise RWF-22474/27: address this question within its stated limits.
Case 32 — Service enquiry: information a watchmaker can use
A service question only says that the watch stops occasionally. Which observations make an initial enquiry more useful?
Exercise RWF-21408/32: address this question within its stated limits.
Case 41 — Movement identification: the limits of a rotor photograph · source wording exercise
Reader check for “Movement identification: the limits of a rotor photograph”: distinguish the discussion point “Ask a qualified watchmaker to inspect it if identification matters for…” 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 24 — 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.
Micro-adjust spacing varies by clasp. Measure the actual change at each setting rather than assuming a standard number of millimetres; compare the usable range with the link length.
Treat the comparison as inconclusive. Repeat with equal light source, charging duration, elapsed time and camera settings; disclose conditions rather than assigning an unsupported quality score.
Case 20 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
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.
