Quick OHR comparison from this morning’s commute to work.
Polar OH1 (left upper arm)
Suunto 7 (left wrist)Distance: 8,87 km
Duration: 24:45
Temperature: -6 CPolar: avg 128bpm, max 150bpm
Suunto: avg 122bpm, max 151bpm
S7 = redIf I look at the course profile the S7 should be more right in the beginning but it’s hard to say, what was the reality.
I’ll try it again on my way home and also with running. -
@JANTIKAINEN I’d say it’s not a very fair comparison
-6 is cold enough to skew something on your wrists when compared to the upper arm blood flow wise. Even mid-course due to wind and stuff.
Also, were you on the bike? That would skew things even further. Generally, wrist location is OK for the bike, but only OK… Upper arm would again have a much better blood flow at all times.
I’d recommend comparing apples to apples: wrist vs wrist. Or better still a strap vs S7. Preferably in activity like running that doesn’t involve wrist flexion.
-
@NickK Yes I was on a bike and yes I think also that it’s not a fair comparison overall, not even if I would be in ideal conditions. Cycling and WHR has never worked for me and looking at the merged chart I find S7 very good.
So my point here was that S7 performs very good. When looking at the course profile it’s actually makes more sense. -
Alright. I ll take this now for a ride and see how the S7 performs in 1c in VogelenSang

I know
But since you are taking the time and effort to do the comparison, we may as well do it strict 
So, certain watch fashion bloggers wouldn’t discount that as flawed. Likewise, if Suunto 7 does fail in one regard or another, I’m sure Suunto would like to know about exact circumstances and benchmarks. -
@NickK I’ll be heading home with my bike in a moment and will try the OH1 in my right wrist vs. S7 on the left.
Temperature at the moment is +1 celcius. -
Ok sorry I broke my promise. Forgot to charge the s7
-
Cycling 8.89 km
Temperature: +1 C
Left wrist: S7
Right wrist: OH1Suunto: avg 118 bpm, max 147 bpm
Polar: avg 122 bpm, max 149 bpm

@JANTIKAINEN I’m really interested in those two spots (middle and end) where sensors disagreed. Do you feel OH1 was right? What was happening on the route?
-
@NickK
The middle part is a section where’s lot of pedestrians crossing the bike lane so this is probably the slowest part of the route. I think the reality could be somewhere between the 2 readings.The end part is strange. The highest OH1 peak is the peak of not so steep uphill. Looks like S7 comes a bit behind but doesn’t reach as high. At the very end where S7 goes down is actually correct, since I’ve already stopped but OH1 still makes a bump up.
-
Here are three comparisons for HR with S7 and S9 using the Suunto Smartsensor. One is SkiTouring and two are intervals for trail running. Temp for ski was -3C and for running was not above 5C.
Run (started S9 again so starts late)
Run
Ski

@Brad_Olwin yes, kind of, but I would like things in different places

Fair enough but, realistically is it just convenience where the fields are? For priorities I would rather have adjustable zones and route import long before we have screen customization. The current modes are not ideal for me but they work well enough.
-
we are getting slightly off-topic here, shall we put all those OHR comparisons in another topic?
I’m just watching the his review video about the S7. Highly interesting for me to see all those menus and stuff. And I really agree with some stuff he says. But I’m also quite sure some of the issues will be solved.
-
@jthomi yes I think a separate section for OHR is a good idea.
-
@JANTIKAINEN feel free to start a discussion
-
Yup that would be nice (OHR)
-
@NickK Coincidentally enough, I had purchased a Venu, and as of today it is packed in the return box with the UPS label ready to be sent back to Amazon. I gave it an honest go with the Garmin Venu, but too many features missing (such as basic audio prompts at each kilometre to announce pace, duration and distance).
Now I am back to looking at the Suunto 7, but so many negative comments, I may just wait out Samsung to see what the Galaxy Watch 2 has in store. -
@EbertsR
You can have a nice bedtime reading today
