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.

Case 11 — Disputed observation: is this dial colour shift real or just lighting?
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.
Case 15 — QC photographs: perspective or a genuinely tilted index?
Request a level straight-on image with the hands clear of the marker. Compare two independently aligned images before drawing a conclusion; an overlay cannot correct an oblique camera angle.
Case 56 — QC photography: what photos actually help verify a pre-owned listing? · source wording exercise
When asking a seller for extra photos of a pre-owned watch, what shots are actually useful as evidence? Listings tend to have glossy angled photos that hide more than they show. I'd like a standard request list the forum can reuse.
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Flash flattens printing and hides…” as the discussion anchor; no new event or result is supplied.

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.

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.

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.

Case 17 — Service enquiry: information a watchmaker can use
Document when it stops, winding behaviour, recent impacts and the positions in which it happens. Be honest about the watch and request an assessment before approving work or ordering parts.
Case 48 — Forum comparison archive: link the evidence and the correction · source wording exercise
Method note for “Forum comparison archive: link the evidence and the correction”: use “Preserve the reasoning trail instead of silently replacing an…” 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 15 — Disputed observation: is this dial colour shift real or just lighting?
Suggested protocol. 1) Both dials in one frame. 2) Diffuse daylight, no direct sun, plus a second shot under neutral indoor light. 3) Grey card visible. 4) No filters, no editing. 5) State camera settings if known. If both shots show the same direction of difference, the claim is supported. If the difference flips between lighting conditions, it's most likely lighting.
