GREAT AND SMALL Garmin Forerunner 255S

Petite, packs a punch and, in fact, it's the smallest full-featured triathlon watch you can buy today

They say good things come in small packages... well, they may have a point when it comes to the Garmin Forerunner 255S. It's a milestone for people with smaller wrists and the new features have made it more than a mere running watch.

The 255S is smaller than the Forerunner 245 used to be and the standard 255, while still possessing the normal five-button layout. Sadly, no versions of the Garmin Forerunner 255 come with an AMOLED display, nor do they have the solar-harvesting Power Glass included - a shame, really, especially considering that other new Garmin watches feature at least one of these.

It does come with all the smart, health and fitness features under the sun, however. These include 24/7 heart rate tracking, sleep tracking, stress tracking, VO2 max estimations, training status reports, smart notifications, weather reports, a quadrillion sports modes - including the new triathlon mode - blood oxygen measurements, Body Battery... the list goes on.
