Research notes

Specification verification pass, 2026-10-25. Updates only the sourced fields in this batch; all other catalog facts and configuration remain unchanged. Manufacturer compatibility requires a supported iPhone; Android pairing is unsupported. GPS model retained; no cellular plan fee inferred. Apple's ECG app listing explicitly excludes Apple Watch SE. Apple's Blood Oxygen support documentation explicitly excludes Apple Watch SE. Earlier research context (2026-10-18); newly verified field notes supersede earlier missing-status statements: 18-hour normal-use claim divided by 24, not 32-hour Low Power Mode. Weight is GPS case only, excluding band. 164 ft is a water-resistance rating, not a safe diving depth. Feature availability depends on region, age and paired iPhone; ECG and SpO2 not inferred from omitted entries. Availability checked 2026-10-18: Manufacturer configurator offers 1.57 in GPS from $249. Source publication/revision date is unreported unless a date is identified above.
