Case 14 — Case finishing: distinguish a reflection from a surface mark
Correction note for “Case finishing: distinguish a reflection from a surface mark”: retain the wording beginning “Ask for photographs with the light moved 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 12 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear
The core trade-off is scratch resistance versus shatter resistance. Sapphire is very hard to scratch but can chip or crack from a sharp impact on an edge. Acrylic scratches easily but flexes, rarely shatters, and light scratches can be polished out at home. Mineral glass sits in between and is often the cheapest to replace.
Add lug-to-lug, thickness and lug width as separate rows. Diameter alone tells you little about wearability. Two cases 2mm apart in diameter can be within 1mm of each other lug to lug, and that number decides whether the watch overhangs a small wrist. Also give the source for each figure: manufacturer sheet, caliper measurement, or catalogue listing.
Case 23 — Maintenance question: how do I tell if an automatic actually needs service?
If the manufacturer provides a suitable procedure, a running-time log can support a service enquiry. State the winding method and stop time. A shortened run does not identify the cause by itself.
Case 5 — Date window centring: compare the same date at the same angle
Clarification for “Date window centring: compare the same date at the same angle”: the point beginning “Use the same numeral, camera axis…” 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 — Model comparison: dive bezel action and alignment, how to compare fairly
Correction to earlier posts in similar threads: 120-click bezels aren't automatically worse. More positions means smaller steps, which can feel less pronounced. Comparing a 60-click and a 120-click bezel on crispness alone is apples to oranges. Compare same-click-count designs, or note the difference clearly.
Case 4 — Date window centring: compare the same date at the same angle
Use the same numeral, camera axis and approximate image scale. Keep the uncropped originals alongside the detail crops and distinguish optical balance from physical window alignment.
If the manufacturer provides a suitable procedure, a running-time log can support a service enquiry. State the winding method and stop time. A shortened run does not identify the cause by itself.
Case 6 — Beginner glossary Q&A: complication, caliber, jewel count, power reserve
One more term that will come up is 'hacking', meaning the seconds hand stops when you pull the crown so you can set the time to the second. It's minor, but beginners often assume every automatic has it, and not all do. That rounds out the glossary: caliber means what, complication means extra functions, jewels mean bearings, power reserve means how long it runs, hacking means precise setting.
Summary draft for “Date window centring: compare the same date at the same angle”: the answer addresses “Keep the uncropped originals alongside the detail crops and distinguish…”; the related point is “Use the same numeral, camera axis…”. 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 41 — Comparing versions without mixing case sizes · source wording exercise
Reader check for “Comparing versions without mixing case sizes”: distinguish the discussion point “List confirmed differences separately from seller descriptions and date the comparison…” 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: source wording. Retain the source wording beside any paraphrase.
Case 21 — QC photographs: perspective or a genuinely tilted index?
Correction note for “QC photographs: perspective or a genuinely tilted index?”: retain the wording beginning “Request a level straight-on image with the hands…” 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.
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.
Case 46 — Crystal types: sapphire, mineral and acrylic trade-offs for daily wear · source wording exercise
Limit of the answer in “Crystal types: sapphire, mineral and acrylic trade-offs for daily wear”: “Sapphire is very hard to scratch but can chip or crack…” 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: source wording. Retain the source wording beside any paraphrase.
Case 21 — Model comparison: dive bezel action and alignment, how to compare fairly
People keep comparing the bezels on two similar dive-style watches. One is called crisp, the other mushy, and alignment complaints come up for both. What would a fair comparison look like, and what is actually a defect versus a preference?
