I have the Garmin 645 right now and it’s fine, gets the job done - but the battery life isn’t what it used to be after around 2 years of using it. I’m planning to get a Pace 2 in the next few months.

UPDATE: GPS stopped working after 18 months...

Great watch while the GPS was working. Small and light. It effectively became useless for my running and cycling workouts after it stopped recording the GPS data 2-3 weeks ago while I was traveling. I bought it in April 2018. Also, the LCD screen started showing an area of dead pixels in the 4-5 o'c...

No issues with lighting at night nor when sleeping. The battery is also very good. Charges fast and lasts a long time. Never had it go to 0 but I think I've used it about a week without charging so far.

First time with Garmin, overall impressed!

Some quick background information. I'm still relatively new to running. I started on a couch to 5k plan a couple of years ago and was hooked! I've since run a number of events (5k, 10k and Half-marathons), and typically run 4 days a week. I thought I would write this review as series over time as I ...

First, the Forerunners are made for running, versus Apple, which doesn't make a running watch. Forerunners are feature rich, good software, and every website/tool works with them. Articles [like are not uncommon: Garmin 645 is seen as the best all-around running watch, the Garmin 245 is best for the money (what I use), and the Garmin 45 is the best budget pick.

Overall great sports watch

So far I'm loving the watch. I enjoy seeing all of the health and running statistics in the Garmin Connect app and I think its a big motivator. The last running watch I had was an old Forerunner 305 that died a few years ago, so I'm really amazed on how much improved the whole experience is along wi...

Which GPS watch is the one to get now?

I've run using an old Tomtom watch for years and have recently upgraded to a Garmin 645. Both work but the Garmin has many more features and a better app. Also a much longer battery life which is why I finally upgraded.

This watch is dying a slow death after 1 year

Let me start off by saying I had originally given this watch a 4 star review. About six months into my purchase Oh, I noticed my vo2max had started to improve. I assumed I was becoming more fit. Little did I know the heart rate sensor was failing a slow death. Now it basically doesn't work at all. I...

Garmin running watches

I have used the Vivoactive 3 for two years and use the forerunner 645 music now...the Vivoactive is incredibly annoying for running. I find it that I was in need of a running watch first and not e-watch if you catch my drift.

Pros and Cons of the Watch

I’ve had this watch for 2 years. It lasted 2 winters and 2 summers and finally broke beyond repair. The part where the strap snaps into the watch face ripped off during a Lysol wipe down.

Pros: it lasts in sweat, rain, sea, pools, showers, etc. The menstrual cycle tracker is an integral part of my ...
