@brechtvb the problem is that different sensors work for different people. Race S is said to be better than the older ones. Apple Watch is said to be excellent, but I read from people where Apple Watch was not working at all. Very difficult topic.
YouTuber ActiveIdeas has a Vertical and says it is spot on for him.
For me the Race S is okay, using a velcro strap. However the strap that came with it gives worse reading. Even 196bpm while cycling home from work while breathing through my nose. A pity because I love that power orange…
That said my Garmin Epix Pro let me down several times as well. 10bpm off while taking a walk in a park…

it’s just not nice coming from a watch where you had the feeling the sensor was working to a new watch where you have the feeling it is not working.
it kinda feels like wasting money and leave you disappointed.
if the watch then also restarts from time to time…though it’s already been a few weeks without a restart…

@Jaakers Well indeed, garmin and coros use the latest HR sensors. Unsure for apple and samsung.
If suunto uses an old unreliable HR sensor, one cannot ask such money for the watches.
Garmin just performs quite well for OHR even on cheap watches.
Some people don’t care about OHR, but we are in 2025 and integrating a lot of sensors in a watch, so we don’t have to use other tools.

@isazi Last year it was March 25th (same as this year), then April 23rd, and finally May 21st. I would have expected at least a bug fix, if only for the Wi-Fi issue, which is quite annoying

As I said before this is not true. Coros has an OHR arm band that recommends to use to have good readings doing sports, you can check their athletes in Instagram, they do not use the watch OHR. Garmin has just presented a new chest strap. So, you have other tools and the brands are telling you, without telling you, that do not trust your OHR.
Is you are a little bit serious in any sports you won’t rely in the watch OHR, in my opinion is only useful for daily tracking, very easy walks and night sleep.

If you practice any sport other than just recreational around your home, you use a chest band. No watch: Garmin, Coros, Suunto, Polar are not suitable for precise heart rate measurement and setting zones with the help of, for example, a watch.
When you go for a professional zones test, no one measures your heart rate from your watch, but from chest band
The Polar H10 seems to be the best and most accurate one available at the moment.
-
@Adrian.S In fact, now a days, you can get your zones using ZoneSense with the chest strap. In my opinion ZoneSense is “the feature” and a killer for the other brands, only for this the watch is worth the money.
I have the chest strap form Suunto, the Polar H10 and the Coros arm band, in my opinion the most comfortable is the coros armband but of course is not as reliable/quick reacting as the chest strap and not compatible with ZoneSense. Between the Polar H10 and the Suunto smart band I do not see any difference in accuracy and the Suunto is samller and more comfortable than the Polar, besides the Polar is more hard with the battery. In the other hand the Polar can have 2 simultaneous BT connections and one ANT+ whilst the Sunnto only one connection.
-
5 more answers and hrv is not reliable anymore…
i think most of us are not serious athletes…
but i had the feeling that running in the correct zones was doable with my previous watch and it probably (99% sure) was.
if not, then how many people are pretending to be doing ok when actually there are not? -

Still not following this.
Garmin does a better OHR than suunto, it’s a simple as that. All brands provide a chest strap, it’s a different type of sensor, more accurate indeed.
But for many people that do some cycling/running/whatever and want a good indiciation of their heart rate, OHR is sufficient, and garmin does it better for less money.
-
For whatever reason, I’m one of those who get wrong OHR readings from the Race. For example, it will regularly measure upwards of 90 BPM sitting still, when by manual method I can measure lower than 60 BPM.
With the right expectation, I can accept the error and use a chest monitor during exercise. The watch is so great, I told myself I would do just that and live with the OHR problems. But my biggest issue came with sleep monitoring and confirming cool down.
What is the point of accepting what is wrong generally 85% of the time when the data is used in calculated feedback? It’s an honest question, in the hope someone could give me some insight I didn’t consider… seriously, I’m hoping for a reason to keep using this thing!

Long time Suunto user here, you guys clearly didn’t use a Suunto 9/9 Baro, THAT was a watch with unreliable OHR.
Agreed with @cosme.costa, since S9P, Suunto’s OHR offering has been getting better and better, now SRS is the best OHR from Suunto (Suunto Run due in a few might take that crown due to less heavy materials
).Anyways, my advise for those seeing bad OHR on Suunto watches while exercising, just try a couple of things:
A) wear it on your less dominant hand (it does make a difference, at least it does on me)
B) wear it at least once finger width above wrist bone like shown below :
Read more tips from Suunto on how to get better OHR readings here.
https://us.suunto.com/pages/how-to-get-more-accurate-wrist-heart-rate-readingsEither way, if you own a Suunto, ZoneSense is such a hook, should have you interested in wearing HR chest strap most of the time
Hope that helps.

A long time suunto user as well. A few points:
- The oHR is decent should you keep your wrist a bit steady. If the way is to wear thw watch a bit higher or to have a different strap, or by how you clench your fist… it’s up to you. I measured this multiple times and is like spot on. Otherwise it does fluctuate, but does it really matter? If it does, wear a chest strap , if it doesn’t , it doesn’t really matter .
- I cannot understand why would anyone care about sleep tracking through a consumer product… You do know that your body was created to give you those indicators right? One may argue that it is advertised it does make a difference… You are right, most sports’ watches do … but it’s time to get back to reality and understand, it’s almost as accurate as coffee fortune telling …
- do you like the watch? use it, you don’t like it and you can afford to replace, do so.
- Do you train for the number of metrics shown or for the training/fun/exercise/experience ? if it’s the latter, use your watches for what it was made for… if its the former… then there are better options that have hundreds of metrics with quite broad usage (not questionable value)
There are people who train as if they are in a hamster wheel , others who do it for fun, others who are professionals etc… I don’t train/exercise to make a living neither do I do it because someone (or a watch) tells me so . I do it because i Like it hence i quite enjoy my vertical

I’ve been using or testing other brands than Suunto : Garmin, coros, polar
None of any model of any brand works fine on me while exercising.
I’m using HR strap if I want accuracy.
Some of my close friend have excellent accuracy with Suuntos, other with Garmins. Not me.
Its not a disappointment : it’s works fine for daily and sleep tracking, and I use hr strap because I want accuracy anyway while exercising and also zonesens. -

maybe your sensor is defective, owning a Race for more than one year I can say that my HR readings are mostly correct when not doing sport activities. When at sleep also oxygen saturation looks good (while it’s always wrong when awake)
