Lug width is the essential one: the inside distance between the lugs where the strap fits. Measure with a ruler marked in millimetres, ideally reading it under magnification. Most watches use even numbers (18, 20, 22mm), but odd widths exist. If you measure 19 or 21, measure again and check the manufacturer spec before ordering.

Case 16 — Movement identification: the limits of a rotor photograph
Only part of the movement is visible and the rotor hides several bridges. Which details can be described without claiming certainty?
Exercise RWF-26823/16: address this question within its stated limits.
Limit of the answer in “Comparing dial colour under different lighting”: “State the lighting and…” 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.
Case 34 — Case finishing: distinguish a reflection from a surface mark
Ask for photographs with the light moved and retain the same viewing angle. A mark should be assessed across multiple views; aggressive polishing is not an appropriate diagnostic test.
Correction note for “Beginner glossary Q&A: complication, caliber, jewel count, power reserve”: retain the wording beginning “Caliber is the movement's model designation,…” 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.

Clarification for “Magnetism and rate: record evidence before naming a cause”: the point beginning “Record the change and the circumstances without treating…” 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 11 — Model comparison: dive bezel action and alignment, how to compare fairly
People keep comparing the bezels on two similar dive-style watches. One is called crisp, the other mushy, and alignment complaints come up for both. What would a fair comparison look like, and what is actually a defect versus a preference?

Case 25 — 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.
Clarification for “Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log”: the point beginning “Diameter alone tells you little…” 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 6 — Packing photographs: document condition without exposing an address
A condition record is useful but a shipping label contains personal information. How can the record be shared safely?
Exercise RWF-15832/6: address this question within its stated limits.
Case 35 — Clasp photographs: what to request before judging alignment
Correction note for “Clasp photographs: what to request before judging alignment”: retain the wording beginning “Request open and closed views from both sides,…” 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 17 — Shipping timeline: separate dispatch, handover and scan events
Limit of the answer in “Shipping timeline: separate dispatch, handover and scan events”: “Distinguish label creation from physical acceptance and retain dated…” 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.
Case 17 — Model comparison: dive bezel action and alignment, how to compare fairly
Summary table proposal: click count, back-play (none, slight, noticeable), click consistency around the rotation, and alignment (straight-on photo, offset in fractions of a click). With that, the thread can compare actual properties instead of trading adjectives. Dated corrections welcome below.
Case 37 — Disputed observation: is this dial colour shift real or just lighting? · source wording exercise
Clarification for “Disputed observation: is this dial colour shift real or just lighting?”: the point beginning “Two photos of the same dial under different light can…” 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.
