Case 32 — 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 19 — Timegrapher reading context: what do rate, amplitude and beat error actually tell me?
I ran a watch on a basic timegrapher and got +6 s/d, 245 degrees amplitude and 0.8 ms beat error, dial up, about an hour after winding. Is this good, bad or normal? I don't want to send it for service on a single reading.

Case 16 — Comparing versions without mixing case sizes
Summary draft for “Comparing versions without mixing case sizes”: the answer addresses “Match reference, dimensions and…”; the related point is “List confirmed differences separately from seller descriptions and date the comparison…”. 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 21 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
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.
Case 10 — Comparing versions without mixing case sizes
Limit of the answer in “Comparing versions without mixing case sizes”: “Match reference, dimensions 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 201 — Maintenance question: how do I tell if an automatic actually needs service? · correction exercise
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?
Review focus: correction. Preserve the old wording if a later source changes the interpretation. Use the original answer fragment “Once you have that, later…” as the discussion anchor; no new event or result is supplied.
Exercise RWF-25905/201: address this question within its stated limits.
Keep the date, work performed, provider invoice reference and test results where available. Redact addresses and payment information; do not invent service events to fill an empty history.
Case 14 — Maintenance question: how do I tell if an automatic actually needs service?
Sealing and movement performance are separate questions. Ask a qualified watchmaker about inspection and testing appropriate to the particular watch and its intended use; a healthy rate does not establish water resistance.
Case 18 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
My entry-level automatic loses about 8 seconds a day. The spec sheet lists a tolerance range, but I'm not sure how to read it or whether my measurement is reliable. Is this something to fix or something to live with?

Case 36 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
Thickness matters more than people expect. Straps around 4 to 5mm at the lugs can hit the case or stop the strap folding down on watches with short lugs or tight lug-to-case clearance. Do you know whether your watch has drilled lugs or a tight gap between strap and case? That tells you how much thickness is safe.
Case 22 — 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 3 — Service enquiry: information a watchmaker can use
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Document when it stops, winding behaviour, recent impacts and…” 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 4 — Lume questions: why does my lume fade so quickly, and how should I compare it?
Use a consistent charge, fixed exposure and several elapsed-time observations. Record readability and the conditions rather than applying an unsupported universal fade-time threshold.
Case 24 — Case finishing: distinguish a reflection from a surface mark
Summary draft for “Case finishing: distinguish a reflection from a surface mark”: the answer addresses “Ask for photographs with the light moved and…”; the related point is “A mark should be assessed across multiple views; aggressive polishing…”. 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 10 — Lug-to-lug and end-link overhang in wrist photographs
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.
