Case 23 — What a water-resistance claim does and does not establish
Correction note for “What a water-resistance claim does and does not establish”: retain the wording beginning “Ask a qualified watchmaker about a suitable test for that individual…” 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.
Case 13 — Date window centring: compare the same date at the same angle
Limit of the answer in “Date window centring: compare the same date at the same angle”: “Use the same numeral, camera axis…” 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.
Keep the complete recording and ask for the settings, winding state and position. A single number cannot establish service condition, movement identity or performance on a wrist.
Case 17 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
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 82 — Seller review template: facts, dates and unresolved questions · comparison exercise
Clarification for “Seller review template: facts, dates and unresolved questions”: the point beginning “Use fields for order date, promised terms, dated…” 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: comparison. Make the basis of a comparison explicit before interpreting it.
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.
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
Record wrist circumference, removable links and the clasp adjustment range in millimetres. Request the closed bracelet circumference rather than inferring it from marketing dimensions.
Case 6 — Clasp photographs: what to request before judging alignment
The available image hides the hinge and only shows the outer surface. Which additional views would answer the question?
Exercise RWF-24037/6: address this question within its stated limits.
Case 21 — 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.
State whether thickness includes the highest point of a domed crystal. Different measurement methods can produce different figures, so keep both the source and method beside each dimension.
Case 39 — 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?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Comparing against a phone clock once a day for a week,…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-20169/39: address this question within its stated limits.
Case 25 — First QC request: the minimum useful information
What should an initial QC request include so replies can address the actual question?
Exercise RWF-19200/25: address this question within its stated limits.
Case 29 — What a water-resistance claim does and does not establish
Ask a qualified watchmaker about a suitable test for that individual case and record the test date and method. A photograph or a caseback engraving is not proof of water resistance.
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.
