hi everyone welcome back to wesknows tech news and reviews today we'll be talking about the huawei
watch fit so this is the smart watch that i've got right here so it does look like the honor watch
yes but no it's the fit so the biggest differences are the fact that it's got continuous spo2
monitoring so this is already a very premium feature another awesome feature is that it's
got dual inbuilt gps and today we'll be checking how accurate the heart rate sensor on the back
of this watch is as well as the gps accuracy let's get into it if you are new to westnow's
tech news and reviews we talk about the latest tech news we do brutally honest reviews and
share hacks and tricks along the way so how did i actually do the test so i went to the park and
well this is the park it's more like a forest it's not really a park it's quite dirty and rugged so
i went out for about 45 minutes i was going uphill downhill all over the show sometimes in the middle
as soon as i saw a bench i would get down on it i would do some push-ups some press-ups then i
would be doing some lunges as well as squats then without a break i would continue walking
sometimes you'll be downhill sometimes uphill so in some cases it was quite intense in some cases
it was a bit more relaxed but overall there's 45 minutes of activity which i was measuring
now the benchmark for this particular exercise these 45 minutes was the polar h10 ecg chest strap
so that provided the heart rate benchmark so we'll be comparing the heart rate accuracy
of the huawei watch fit optical heart rate sensor versus the polar h10 now in regards to the gps
i was using two apps so the polar beat as well as the gpx app on my iphone 12 and of course we're
going to be using that as the benchmark and the gps the inbuilt gps on the huawei watch fit so the
polar h10 as well as the iphone 12 with a number of apps are the benchmarks and of course this is
the tester device so now let me tell you some key facts about the huawei watch and then we can get
into the numbers into the details right so let's quickly have a chat about the huawei watch fit if
we talk about the display this smartwatch is also quite premium the screen size is 1.64 inches and
the fact is it's an amoled display bright it's crisp the contrast is very high and you can see
any of the notifications any of the metrics and stats in any light conditions another important
factor even though it's a budget smartwatch you don't only have the brightness levels you also
have an ambient light sensor here that means that it does have auto brightness available
obviously you will need to use the huawei health app with this smartwatch and that will give you
an absolutely huge amount of downloadable faces there's been a couple of updates to the smartwatch
and now you can upload doesn't matter if you're using an android or an ios device you can upload
your photos from your camera from your phone onto the watch face as custom faces and that
is very handy and quite cool now let's talk about the features and functions if we talk about the
features though let me say we're not going to be covering off things like your timer your stopwatch
your weather widgets no that's basic i want to talk about those things that make this budget
smartwatch so absolutely cool and quite premium so what's really cool about the huawei watch
well the fact is it's got 95 sport modes that's plenty that's more than any of us or most of us
will ever use on top of that there is a dedicated running app which will which will guide you
through 13 running courses and can get you running from whether you're a newbie to an expert runner
on top of that there's a workout course and in it there are 44 animated gestures and these animated
gestures do look great they will actually show you how to perform a particular exercise
they will time you they will guide you through those exercises that's handy that's useful and
it will save you from any injuries really because you can actually see how you should perform
those particular exercises on top of that there is dual inbuilt gps this smartwatch is waterproof up
to 50 meters so you've got no issues with taking it to the shower to the pool in fact because it
does have the inbuilt gps you can take it to open water swimming so go to a lake go to the sea well
do whatever you need this thing can take it if we talk generally about the sensors on this so
you've got continuous heart rate monitoring then you've got continuous stress monitoring you've
also got sleep monitoring and it does measure your light sleep your deep sleep and rem sleep so the
full three stages and considering it does use the huawei true sleep technology which was the which
was developed with the harvard medical school so there is a claim to fame another really awesome
thing about this particular smartwatch is that it can track your spo2 but not just the on-demand and
the spot spo2 readings it can actually monitor and track your spo2 or your blood oxygen saturation
over a period of time it can track it continuously and that is very useful and quite premium i don't
know of any other smart watch under 150 or 200 bucks that can do it today and we've actually
done a previous test on that and you will see that the accuracy is spot-on and it's just
as good as the garmin venue i will put a link to that particular video just above me right now
anyway now that we've discussed all the positives about this particular smartwatch let's talk about
the actual test let's get into the numbers let's check how accurate the heart rate sensor is as
well as the gps first of all let's touch upon the heart rate accuracy so we know that the benchmark
was the polar h-10 ecg chest strap now the polar h-10 is supposedly one of the best of one of the
most accurate heart rate trackers ecg hardware trackers in the world it's actually being used
for scientific studies for medical studies as well as by professional athletes so it does
have claim to fame and it is quite a trusted device so let's have a look at the plot so we
can see that the polar h10 has actually measured the average heart rate at 128 beats per minute
while the max was 160 beats per minute so we can see that this smartwatch has actually
measured the average heart rate of 124 beats per minute while the max was 153 beats per minute so
that is four beats per minute underestimated for the average and seven underestimated for
the max when we look at the plot we can see that in general the tracing is quite good
there were only a number of points where a peak was overestimated by the smartwatch over what
was recorded by the polar h10 but that's at the start of the actual walk so in the first half
in the first 20 minutes or so as we get into the second half of the activity we can see that there
was a max being hit and that's the 160 beats per minute as registered by the polar h10 and
the smartwatch actually underestimated that peak so overall we can see that in some of the cases
the smartwatch did underestimate the heart rate as opposed to the polar h10 ecg chest strap
and that does give us this lower average and the lower peak now is the difference that major well
i don't think so it's all generally under 5 so over 45 minutes that's quite a lot of data there
now let's take a look at the gps accuracy because there were a couple of issues here
we can see that the gps as calculated by iphone 12 using polar beat gave us 3.5 kilometers while
the watch actually gives us 2.81 kilometers that is quite a massive difference that's a difference
of about 20 percent and the previous tests we've done the gps tests with the huawei watch
it has shown approximately the same differences but anyway these are the results let's sum it up
if you want a smart watch which is very sporty which has got a lovely design a huge 1.64 inch
amoled display then the huawei watch fit is amazing it's a great fit the price is budget
it offers 95 sport modes there's a workout course there's a running app there's just
so much i can just say that with some of the features offered by this smartwatch
i don't think you can get a better deal on the market today and that's particularly if
you're after the sports if you're after swimming and you do want to do some open water swimming
