Case 2 — Date window centring: compare the same date at the same angle
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
Exercise RWF-28599/2: address this question within its stated limits.
Case 25 — QC checklist: prioritise observable faults over pixel hunting
A large crop makes tiny differences look dramatic. How can a checklist remain proportionate?
Exercise RWF-26465/25: address this question within its stated limits.
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.
Describe visible bridge shapes and markings separately from the proposed identification. Ask a qualified watchmaker to inspect it if identification matters for servicing; do not open the case merely for a forum answer.
Case 7 — Model comparison: dive bezel action and alignment, how to compare fairly
Separate three properties: click count (60 or 120 positions), feel (how firm each click is, and whether there's back-play), and alignment (whether the pip lines up with the 12 o'clock marker at rest). Crisp vs mushy is mostly about feel and back-play. Alignment can be measured, so treat it separately.
A notation like 20/16 means 20mm at the lugs, tapering to 16mm at the buckle. Taper affects look and comfort more than fit. A strong taper suits smaller and dressier cases, a straight strap suits sport watches. Your buckle or clasp also has to match the narrow end, so check that if you want to reuse an existing buckle.
Case 9 — Crystal reflections: why a dark patch is not a coating test
Correction note for “Crystal reflections: why a dark patch is not a coating test”: retain the wording beginning “No single lighting setup settles…” 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 22 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
Resolution checklist. 1) Rebalance links around the clasp. 2) Test every micro-adjust hole with each link count. 3) Check fit morning and afternoon. 4) Look for half-links by bracelet reference. 5) Accept slightly loose if the head is light. If none of that works, a strap with finer hole spacing is a reasonable conclusion, not a failure.
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.
Reader check for “Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?”: distinguish the discussion point “Start with how you…” 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.
Photograph the item and protective packing separately from the label. Remove names, addresses, barcodes and tracking tokens from public images while keeping originals privately.
Summary draft for “Beginner glossary Q&A: complication, caliber, jewel count, power reserve”: the answer addresses “Caliber is the movement's model designation,…”; the related point is “Two watches from different brands can share the same caliber…”. 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 5 — 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.
Case 12 — Date window centring: compare the same date at the same angle
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved?
Exercise RWF-10445/12: address this question within its stated limits.
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.
