Very "complete" watch.

  • Lots of tools
  • Including training programming
  • Nice and accurate navigation
  • 255s is only available in pink and gray strap.

Highly recommended for the recreational runner. Will definitely take you to a higher level. Very motivating.

Top for intermediate/advanced runners

  • Good for smaller wrists
  • Many possibilities
  • Good connection with mobile phone/headphones for calling, controlling music, etc.
  • I don't think buttons are entirely logical

Really liked it so far! I have small wrists and this is large enough to be able to read all the statistics while walking, but small enough that it stays in place. Battery lasts a long time, many programs/activity options. I mainly use it for running, which I think is great so far. Very easy to create workouts/routes and sync them with the watch. So far the GPS has been very accurate, my previous watch had a lot of trouble with laps in the park, but this one measures that well too.

The buttons take some getting used to, I had a Polar watch before and found the order/function of those buttons more logical. I think it's a shame that Garmin doesn't have a coaching program for a full marathon, but I use the half marathon program and am happy with it so far. All in all a comfortable watch with all the features I would want for running!

Many options, highly recommended

  • Versatile and complete
  • Many functions

The watch offers many functions and insights that make running a little more fun for me. The training schedules and insights help me achieve my goals. It takes some getting used to how everything works, but you get the hang of it quickly enough.
