Case 13 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Correction to a common shortcut: don't measure lug width on an existing strap. Leather and rubber straps compress or swell, and some are made slightly undersized on purpose. Always measure between the lugs themselves, with the strap removed if possible.
Case 26 — Maintenance question: how do I tell if an automatic actually needs service?
Common advice says service every five years, but service is expensive and some people run watches much longer. What observable signs actually indicate a mechanical watch needs attention, as opposed to just being due on a calendar?

Case 40 — Movement identification: the limits of a rotor photograph · source wording exercise
Reader check for “Movement identification: the limits of a rotor photograph”: distinguish the discussion point “Ask a qualified watchmaker to inspect it if identification matters for…” 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 39 — Lume comparison: keep exposure and charging conditions consistent · source wording exercise
Summary draft for “Lume comparison: keep exposure and charging conditions consistent”: the answer addresses “Repeat with equal light source, charging duration, elapsed time and camera…”; the related point is “Treat the comparison…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
Case 13 — First QC request: the minimum useful information
Method note for “First QC request: the minimum useful information”: use “State the model configuration, the specific concern and…” 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.
Method note for “Movement identification: the limits of a rotor photograph”: use “Describe visible bridge shapes and markings separately…” 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 51 — What a water-resistance claim does and does not establish · source wording exercise
Limit of the answer in “What a water-resistance claim does and does not establish”: “A photograph or a caseback engraving is not…” 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: source wording. Retain the source wording beside any paraphrase.
Case 35 — Case finishing: distinguish a reflection from a surface mark
A bright line appears in one polished-case image. What additional evidence would distinguish a mark from reflected light?
Exercise RWF-21341/35: address this question within its stated limits.
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.
Summary draft for “Crown operation: when a forum cannot diagnose the resistance”: the answer addresses “Describe whether resistance occurs during winding or setting and…”; the related point is “Stop forcing it and arrange inspection rather than trying…”. Keep both connected to the opening question, and mark any conclusion needing further records as unresolved. Review focus: source wording. Retain the source wording beside any paraphrase.
A correction worth making: 'sapphire = premium, mineral = cheap' oversimplifies it. A well-fitted mineral crystal on a modest watch can be perfectly suitable, and replacing a cracked sapphire is usually more expensive. Material is one factor among several, alongside fit, gasket quality and coating.
A sudden rate change has several possible causes. Ask a watchmaker to test suspected magnetism rather than diagnosing it from a compass or attempting an adjustment based on forum replies.
Method note for “Date window centring: compare the same date at the same angle”: use “Use the same numeral, camera axis…” 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 1 — Packing photographs: document condition without exposing an address
Summary draft for “Packing photographs: document condition without exposing an address”: the answer addresses “Photograph the item and protective packing…”; the related point is “Remove names, addresses, barcodes and tracking tokens from public…”. 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.
Case 2 — Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log
I'm putting together a side-by-side of the 38mm and 40mm versions of a common three-hand field watch design. The aim is a reference post we can fix over time instead of repeating the same arguments. Corrections go in a dated log at the bottom. What should the table include besides case diameter, and which specs are usually misreported?
