Garmin's 255 Music is a great fitness watch that has all the features a loyal customer wants. It has a bigger screen, better resolution, GPS that locks almost immediately, sturdier buttons, more useful training statistics, and the music function without crashes. It also has a smaller face size and wrist band, allowing it to fit on the wrist during the night. However, the color selection is a bit odd, and the heart rate tracking is not always accurate.
