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 5 — Movement identification: the limits of a rotor photograph
Limit of the answer in “Movement identification: the limits of a rotor photograph”: “Describe visible bridge shapes and markings separately…” 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.
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.
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 complication is any function beyond hours, minutes and seconds. A date window counts, technically, and so do a chronograph, GMT hand or moon phase. More complications usually mean more parts, more thickness and more service cost. For a first everyday watch, decide which functions you'd really use before treating them as value.
Correction note for “Lug-to-lug and end-link overhang in wrist photographs”: retain the wording beginning “Record lug-to-lug and the effective span…” 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 9 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
On anti-reflective coatings: inner-surface AR cuts glare without wear concerns. Outer-surface AR improves legibility further but can scuff over time, and the scuffs show up as hazy patches in certain light. When comparing two watches, check which surfaces are coated. Spec sheets often just say 'AR coated' without saying where.
Case 13 — 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?
Exercise RWF-24433/13: address this question within its stated limits.
Reader check for “QC photography: what photos actually help verify a pre-owned listing?”: distinguish the discussion point “Ask for a straight-on dial photo with diffuse light and no…” 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: scope. Keep the stated question separate from any broader claim.
Case 10 — Reading a timegrapher recording without losing the context
Summary draft for “Reading a timegrapher recording without losing the context”: the answer addresses “Keep the complete recording and ask for the…”; the related point is “A single number cannot establish service condition, movement identity…”. 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 1 — Seller review template: facts, dates and unresolved questions
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.
Case 51 — Service enquiry: information a watchmaker can use · source wording exercise
A service question only says that the watch stops occasionally. Which observations make an initial enquiry more useful?
Review focus: source wording. Retain the source wording beside any paraphrase. Use the original answer fragment “Be honest about the watch and request an assessment…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-19445/51: 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.
Case 5 — 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.
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.
