Case 25 — Comparing dial colour under different lighting
One image was taken beside a window and the other under a warm lamp. How should a colour comparison be qualified?

Clarification for “Case finishing: distinguish a reflection from a surface mark”: the point beginning “Ask for photographs with the light moved and…” 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.
State the lighting and white-balance limitations. Compare controlled images where available and avoid calling a colour defect from differently processed photographs.
Case 36 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Regulation is possible if you want it closer. On many movements it's a quick adjustment by a watchmaker. Can you check whether the losing rate is consistent or getting worse? A stable -8 is a good candidate for simple regulation. A growing loss points to something else, such as falling amplitude, and regulation alone won't fix that.
Case 38 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained · source wording exercise
Reader check for “Strap dimensions: lug width, taper, thickness and spring bar diameter explained”: distinguish the discussion point “Measure with a ruler marked in millimetres, ideally…” 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 40 — Date window centring: compare the same date at the same angle · source wording exercise
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Keep the uncropped originals alongside the detail crops and distinguish…” 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 19 — Reading a timegrapher recording without losing the context
The supplied screen shows a rate but does not identify the lift angle, position or winding state. Which observations should accompany the recording?
Exercise RWF-24476/19: 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.
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 4 — What a water-resistance claim does and does not establish
Method note for “What a water-resistance claim does and does not establish”: use “Ask a qualified watchmaker about a suitable test for that individual…” 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.
No single lighting setup settles that question. Compare multiple controlled angles and describe the visible observation without asserting material specifications that have not been verified.
A practical test without a camera: charge both watches the same way, sit in a dark room, and check readability at 5 minutes, 30 minutes and 2 hours. Write down which you can still read the time on. It's subjective but repeatable, and more useful than a single photo.
Case 5 — Packing photographs: document condition without exposing an address
Method note for “Packing photographs: document condition without exposing an address”: use “Photograph the item and protective packing…” 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.
Correction note for “QC checklist: prioritise observable faults over pixel hunting”: retain the wording beginning “Start with function, legibility, assembly and…” 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.
