The lift angle must match the movement specification for the amplitude reading to be meaningful. If it is unknown, label amplitude as provisional instead of accepting the instrument default.

Case 7 — Comparing versions without mixing case sizes
Two purported versions differ in case diameter and bracelet. How can the comparison avoid attributing every difference to a revision?
Exercise RWF-30442/7: address this question within its stated limits.
Case 11 — Date window centring: compare the same date at the same angle
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Use the same numeral, camera axis…” 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.
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
Case 31 — Forum comparison archive: link the evidence and the correction
Summary draft for “Forum comparison archive: link the evidence and the correction”: the answer addresses “Add a dated correction near the original conclusion…”; the related point is “Preserve the reasoning trail instead of silently replacing an…”. 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.
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.
Use fields for order date, promised terms, dated communications, delivery evidence and resolution. Leave unsupported fields blank and separate observations from opinions; this reference is not a seller endorsement.
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: source wording. Retain the source wording beside any paraphrase.
Case 34 — Disputed observation: is this dial colour shift real or just lighting?
Status for now: unresolved. The claim is plausible, but no controlled comparison has been posted. Until one appears, describe it as 'reported, not verified'. When someone posts a same-frame, grey-card comparison under two lighting conditions, the thread can update the status with a date and a link to that post.
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. Retain the source wording beside any paraphrase.
One more term that will come up is 'hacking', meaning the seconds hand stops when you pull the crown so you can set the time to the second. It's minor, but beginners often assume every automatic has it, and not all do. That rounds out the glossary: caliber means what, complication means extra functions, jewels mean bearings, power reserve means how long it runs, hacking means precise setting.
Method note for “QC photographs: perspective or a genuinely tilted index?”: use “Request a level straight-on image with the hands…” 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.
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.
Limit of the answer in “Lume questions: why does my lume fade so quickly, and how should I compare it?”: “A bright initial glow followed by a steep drop…” 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.
If the manufacturer provides a suitable procedure, a running-time log can support a service enquiry. State the winding method and stop time. A shortened run does not identify the cause by itself.
