Rugged outdoor watches

12 models · 7 makers, ~$250–$1,000

Thick cases, military-standard claims, buttons usable with gloves, and battery quoted in weeks, often with a solar figure on top. Several use memory-in-pixel screens that are always on by design, which is why their always-on figure is the same as their headline.

Ordered by price, lowest first.
