9 shortlists, each saying what it ranks on
Nobody here is picking favourites and there is no test lab. Each list below is a filter and an order applied to the catalog, and it prints the rule at the top, so you can argue with the rule rather than with an opinion.
Smartwatches with the longest battery when the screen stays on
21 qualifying watches
Ordered by the maker's own always-on-display figure, longest first, then by price. Watches whose maker publishes no always-on figure are left out rather than guessed.
Watches with the longest GPS battery
42 qualifying watches
Ordered by the maker's figure for a GPS workout in its standard GPS mode, longest first. Dual-band figures, which drain faster, are shown beside it where published.
Wear OS watches, and what each needs from your phone
6 qualifying watches
Every Wear OS watch, ordered by price, with the maker's own statement of what needs its own phone.
Watches that work with an iPhone, other than the Apple Watch
44 qualifying watches
Every watch from a maker other than Apple that pairs with an iPhone, ordered by price.
Smartwatches with an FDA-cleared ECG
15 qualifying watches
Included when the maker's US page or the FDA's database cites a clearance for the watch's ECG feature. Ordered by price. A clearance is not medical advice; it says what the feature may claim.
Watches whose maker sells no paid tier
12 qualifying watches
Included when the maker sells no paid tier for the watch's app. Ordered by price. Carrier plans for LTE models are a separate cost and are noted on each page.
The lightest GPS watches
42 qualifying watches
Ordered by the lightest case size the maker sells, lightest first. Makers weigh differently (with or without the band), and each figure says which.
The cheapest watches with full topo maps
21 qualifying watches
Included when the maker says the watch carries full topographic maps on the watch. Ordered by price.
The cheapest running watches with dual-band GPS
7 qualifying watches
Running watches whose maker lists dual-band (multi-frequency) GPS, ordered by price.
A list needs at least 3 qualifying watches to exist at all; anything shorter is a comparison with a headline on it. How the catalog is built.
