[Demo] Comparison thread: 38mm vs 40mm versions of the same field watch, with a dated correction log · WATCH-11593

Synthetic demo • AI-assisted. Fictional discussion exercise with simulated dates. No real purchase, customer review, patient, expert identity or experimental result is represented.

I'm putting together a side-by-side of the 38mm and 40mm versions of a common three-hand field watch design. The aim is a reference post we can fix over time instead of repeating the same arguments. Corrections go in a dated log at the bottom. What should the table include besides case diameter, and which specs are usually misreported?

Discussion record: WATCH-11593. No additional facts are implied by this exercise format.
