Forerunner 255 wrong open water readings

This is the same open water swim with both fenix 3 and forerunner worn on the same wrist. On the left is 255 and on the right is fenix 3. I I'm using fenix 3 for the last 5 years in training and in triathlon races so I'm pretty sure fenix 3 readings are correct.

People with fenix and epix have same issues. Garmin is quiet about it. I came to this forum to see whether the issue affects new forerunners, and it does. That probably means the issue will not be fixed.

Yes, I have the same problem with the Forerunner 255 Music in open water, what I have realized is that if you download the track from the web version of garmin connect, it measures fewer meters than Garmin Connect shows in its properties. Something is wrong with the software the watch is not displaying the meters correctly during the activity. Let's hope Garmin takes action on the matter. Left Garmin Correct (Web Version) Right Google Earth Track Properties, same track

has anybody updated to the new beta version? Any changes to open water accuracy?

I´m facing similar problem of wrong open water reading with the Forerunner 255, in my case the wacht continue increasing the distance even I'm stopped. When I start the activity, still stopped the distance starts to increase, in the end of activity the distance is greater then the real one. I have tried all Garmin tips to solve this issue. Anyone else is facing this issue and can advice the solution?

7 months passed and not a single response from any garmin rep. It really feels like there will be no change for the better with these garmin watches. 

I'd like to report that after all updates and with the latest firmware the watch is working ok in open water.

So both your watches have the same stats now ?

yes, more or less. Taking of course into consideration all limitations there are in open water gps signal with all sport watches.

Good to know then for those using it in open water. Thx
