GPS, GLONASS, GALILEO, HRM, barometric altimeter, compass, gyroscope, accelerometer, thermometer, SpO2 I'll discuss in the next section why I love the current display, but I think many people will ditch that perk willingly for a more compact fit that's better suited for sleep tracking.Ģ55: 1.3-inch (260x260) MIP 255S: 1.1-inch (218x218) MIPĢ55: 22mm (industry-standard) 255S: 18mm (industry-standard)Ĥ5.6 x 45.6 x 12.9mm 49 grams/1.73 ounces I'm strongly considering buying myself the Forerunner 255S to cut down on the size a bit, even if it means trading away screen space and battery life. Thankfully you can count on the Gorilla Glass 3 to prevent most scratches, but you may want to invest in a third-party screen protector - though I couldn't find many compatible models on Amazon as of yet. I have found it will occasionally catch onto furniture or doorways, in a way other watches wouldn't.

In practice, the watch weighs about the same as many premium running watches which is to say it's noticeable, but doesn't quite drag down your wrist as a larger Forerunner or Fenix would. That's something long-time Garmin fans won't mind, but anyone used to narrower fitness trackers or lifestyle watches may resent. It's still 1.5mm thinner than the Forerunner 955, but it certainly has a hefty profile on your wrist. Despite their many differences, Garmin has a consistent throughline in its most recent devices: They have faster menuing, improved battery life and sensor accuracy, and added software features compared to the previous generation.īut while the 2nd-gen Venu and Instinct models got thinner than their predecessors, the Forerunner 255 is 0.7 millimeters thicker (0.2mm with the smaller 255S) than the 245.
