Case 27 — Magnetism and rate: record evidence before naming a cause
Summary draft for “Magnetism and rate: record evidence before naming a cause”: the answer addresses “Record the change and the circumstances without treating…”; the related point is “A competent watchmaker can test and diagnose it; random adjustment…”. 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.
Method note for “Crown operation: when a forum cannot diagnose the resistance”: use “Describe whether resistance occurs during winding or setting 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 “Date window centring: compare the same date at the same angle”: use “Keep the uncropped originals alongside the detail crops and distinguish…” 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.
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Keep the uncropped originals alongside the detail crops and distinguish…” 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 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.
Clarification for “Crystal reflections: why a dark patch is not a coating test”: the point beginning “No single lighting setup settles…” 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.
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 8 — QC photography: what photos actually help verify a pre-owned listing?
A caution: photos can't settle everything. Water resistance, timekeeping and internal condition aren't visible in any image. A short timegrapher video or a stated recent rate test adds information, but treat it as a seller claim unless an independent party confirms it. Photos narrow the risk. They don't remove it.
Case 33 — 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 13 — Bracelet fit: half-links, micro-adjust holes and the 'between sizes' problem
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 19 — 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 18 — Accuracy expectations: is -8 s/d acceptable on an entry-level automatic?
Log the rate over several comparable days, identify the correct specification and state the conditions. Stable and changing patterns raise different questions; a watchmaker can assess whether regulation, inspection or no action is appropriate.
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.
