Method note for “Crystal reflections: why a dark patch is not a coating test”: use “No single lighting setup settles…” 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 27 — Movement identification: the limits of a rotor photograph
Summary draft for “Movement identification: the limits of a rotor photograph”: the answer addresses “Describe visible bridge shapes and markings separately…”; the related point is “Ask a qualified watchmaker to inspect it if identification matters for…”. 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 7 — 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-28409/7: address this question within its stated limits.
Caliber is the movement's model designation, like a part number. Two watches from different brands can share the same caliber family with different finishing or regulation. On a spec sheet it tells you what's inside and roughly what service parts are available. It doesn't tell you how well that particular example was adjusted.
The difficulty is that phone cameras adjust white balance automatically, and blue dials are especially sensitive. Two photos of the same dial under different light can easily look like a 'batch difference'. Any comparison needs both dials in the same frame, under the same light, ideally next to a neutral grey or white reference card.
Clarification for “Reading a timegrapher recording without losing the context”: the point beginning “Keep the complete recording and ask for the…” 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 8 — Movement identification: the limits of a rotor photograph
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?

Case 39 — Seller review template: facts, dates and unresolved questions · source wording exercise
Method note for “Seller review template: facts, dates and unresolved questions”: use “Leave unsupported fields blank and separate observations from opinions; this…” 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. Retain the source wording beside any paraphrase.
Case 11 — First QC request: the minimum useful information
State the model configuration, the specific concern and links to clear redacted images. Include complete instrument settings where relevant and say explicitly what evidence is missing.
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 46 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Summary draft for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: the answer addresses “Sapphire is very hard to scratch but can chip or crack…”; the related point is “Acrylic scratches easily but flexes, rarely shatters, and light scratches…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
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.
Case 22 — Model comparison: dive bezel action and alignment, how to compare fairly
People keep comparing the bezels on two similar dive-style watches. One is called crisp, the other mushy, and alignment complaints come up for both. What would a fair comparison look like, and what is actually a defect versus a preference?

Case 31 — First QC request: the minimum useful information
Limit of the answer in “First QC request: the minimum useful information”: “State the model configuration, the specific concern 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 11 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
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.
