Case 23 — 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.
Clarifying question first: do you have a baseline? If you've never recorded the watch's rate or power reserve, 'drifting' is hard to judge. Start a simple log now with daily offset against a reference time for a week, and the hours it runs from full wind. Once you have that, later changes mean something.
Case 42 — Service enquiry: information a watchmaker can use · source wording exercise
Clarification for “Service enquiry: information a watchmaker can use”: the point beginning “Be honest about the watch and request an assessment…” 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.
Method note for “Clasp photographs: what to request before judging alignment”: use “Separate cosmetic alignment from whether the clasp engages reliably;…” 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 30 — QC photography: what photos actually help verify a pre-owned listing?
A dated note in the frame can support a claim that photographs are recent, but it is not conclusive proof of ownership, authenticity or an honest transaction. Treat it as one limited check alongside independent verification.
Clarifying question for the thread: is the goal to check authenticity, condition, or both? For condition, the request list above is enough. For authenticity, you also need caseback, serial or reference engravings, and ideally movement photos. Movement photos usually require opening the watch, which a seller may reasonably refuse without a watchmaker present.
Case 23 — Strap compatibility: width is only the first measurement
Two straps share the same nominal width but differ in thickness and spring-bar clearance. Which dimensions need checking?
Exercise RWF-20591/23: address this question within its stated limits.
Case 22 — Crown operation: when a forum cannot diagnose the resistance
Correction note for “Crown operation: when a forum cannot diagnose the resistance”: retain the wording beginning “Describe whether resistance occurs during winding or setting 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. Keep the stated question separate from any broader claim.
Case 28 — Strap compatibility: width is only the first measurement
Two straps share the same nominal width but differ in thickness and spring-bar clearance. Which dimensions need checking?
Exercise RWF-18318/28: 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 32 — Date window centring: compare the same date at the same angle
Summary draft for “Date window centring: compare the same date at the same angle”: the answer addresses “Use the same numeral, camera axis…”; the related point is “Keep the uncropped originals alongside the detail crops and distinguish…”. 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.
First, a clarifying question: how many links are on each side of the clasp right now? Fit often improves by moving one link from the 6 o'clock side to the 12 o'clock side, or the reverse. That doesn't change length, but it shifts where the clasp sits under the wrist, and a centred clasp feels less tight.
Case 27 — Strap dimensions: lug width, taper, thickness and spring bar diameter explained
I want to buy aftermarket straps but keep seeing 20/16, 22mm, 4mm thick and spring bar sizes. Which measurements do I actually need to take from my watch, and how do I measure them without the right tools?
Exercise RWF-13517/27: address this question within its stated limits.
Case 13 — What a water-resistance claim does and does not establish
Method note for “What a water-resistance claim does and does not establish”: use “Ask a qualified watchmaker about a suitable test for that individual…” 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.
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.
