    @watwatch I think it is usable for everyday tracking…

    If you wanna have a review for this, watch dc rainmaker… He was very positive about this.

      @watwatch This is my exact use case. I only rely on the OHR for everyday life/sleep/activity. For any sort of timed activity I always use a HR strap. Used this way the Race S works pretty well for me.

          I’m having issues with the heart rate sensor. It drops out randomly for no obvious reason.

          The first picture is on a gravelbike, but on flat asphalt road. Second picture is real gravel road and actually in the flat part, i was doing concrete roads.

            @brechtvb I’d really recommend an external HR device for any sport such as running or cycling, especially gravel bike or mountain bike. The well respected Reviewer DC Rainmaker basically finds watch OHR never performs well when there’s a lot of movement/vibration. Coospo do some pretty cheap but decent belts and armband OHR sensors (although with optical you won’t be able to use ZoneSense) or there’s the well known manufacturers such as Suunto’s own belt, Wahoo, Polar and Garmin.

            Wrist based OHR is fine for everyday and good enough for aerobics, spin classes or rowing machine but for anything more it’s worth the external sensor 🙂

              @far-blue Below the picture of a bike ride (asphalt, nearly no gravel) with a garmin forerunner 55 (the el-cheapo).

              The drops in heart rate are perfectly explainable to the speed drops. All dots together: a today 150 euro garmin outclasses a 350 euro Suunto in measuring heart rate.

              i have plenty more with (nearly) zero heart rate error.

                @brechtvb I’m glad you feel you can rely on it for your activities 🙂

                However, the internet is littered with posts, comments and reviews from thousands of people who can’t, regardless of whether it’s a $100 amazfit or a $1000 Fenix. The wrist is pretty much the worst possible place to try and take an optical HR reading.

                  @far-blued I’m really unhappy with the optical heart race on My Suunto Race S, the data is inconsistency even though I follow all the wearing tip from the manufacturer. I have not get the similar issue with other optical watch brand.
                  It is very annoying when going out for a run then suddenly there is no heart rate signal on watch or it jump extremely high.

                    @far-blue I sold the forerunner because I sint want to deal with so many devices, obviously.

                      There is a new update: 2.40.38
                      who knows this solves a thing.

                        @brechtvb For me the update solved nothing, perhaps made the OHR situation worse, i.e. fewer reasonable readings (not exercising).

                            @erik_ibk I have the same problem and these are vital things to work so I’m really disappointed this issue has been constant for weeks and nothing is being done, even if MANY people are having the same issues. I think I might return the watch since these issues have been here the whole time I have had this. So disappointing.

                            I can’t just be restarting this all the time and I can’t know when it is not going to measure the sleep. So it’s not helping to restart to get that sleep data back. How is it possible that there has been promised update but it’s been WEEKS? this would have never happened with Garmin. So I guess I have to return this then?
