If you’re into multi-sports, go watch. Cycling only? Go computer. I have suunto spartan ultra. For cycling, I have small piece of pipe insulation on my handlebar for the watch. If it on your wrist when riding you’ll have trouble just like Fast Fred above does.

My my wife does a lot of tri. She had many problems with Garmin Watch. Buttons stop working after a couple of months. Send it in for repair. Same problem after a couple of months. Switched to Suunto. No problems. I’ve had no problems with mine either.
