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.

Case 7 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
Can the same settings and winding state be used for several positions? Record each position separately rather than combining measurements taken under different conditions.
Case 22 — Lug-to-lug and end-link overhang in wrist photographs
A wide-angle wrist photo exaggerates the nearest edge of the case. How can two watches be compared fairly?
Exercise RWF-27179/22: address this question within its stated limits.
Case 33 — Magnetism and rate: record evidence before naming a cause
A sudden rate change is being attributed to magnetism without a measurement. How should the discussion be structured?
Exercise RWF-25919/33: address this question within its stated limits.
Correction note for “A maintenance log that remains useful after a sale”: retain the wording beginning “Keep the date, work performed, provider invoice reference…” 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 25 — Comparing versions without mixing case sizes
Match reference, dimensions and configuration first. List confirmed differences separately from seller descriptions and date the comparison so later readers understand its scope.
Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
Method note for “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: use “Sapphire is very hard to scratch but can chip or crack…” 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 49 — Shipping timeline: separate dispatch, handover and scan events · source wording exercise
Method note for “Shipping timeline: separate dispatch, handover and scan events”: use “Ask the sender or carrier for clarification; missing scans alone…” 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 28 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
Before the table goes live, a question: are you comparing current production only, or older references too? Dial printing, lume colour and crown signing often changed between batches. If older pieces are in scope, add a production-period column, or every disagreement will look like an error when it's really a running change.
Summary so far. Rows: diameter, lug-to-lug, thickness (method stated), lug width, crystal type, water resistance (as specified), movement family, production period. Each row has a source tag. Corrections go in the dated log with old and new values. If nobody objects, that's the template, and later posts should give evidence rather than restate opinions.
Case 16 — Packing photographs: document condition without exposing an address
Clarification for “Packing photographs: document condition without exposing an address”: the point beginning “Photograph the item and protective packing…” 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.
Clarification for “QC photographs: perspective or a genuinely tilted index?”: the point beginning “Compare two independently aligned images before drawing a conclusion; an overlay…” 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.
Case 28 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Resolution checklist. 1) Rebalance links around the clasp. 2) Test every micro-adjust hole with each link count. 3) Check fit morning and afternoon. 4) Look for half-links by bracelet reference. 5) Accept slightly loose if the head is light. If none of that works, a strap with finer hole spacing is a reasonable conclusion, not a failure.
Clarification for “Lug-to-lug and end-link overhang in wrist photographs”: the point beginning “Record lug-to-lug and the effective span…” 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.
