In addition to heart health and blood pressure, it can do an ABPM, which monitors your blood pressure over a 24-hour period and checks your blood oxygen levels.Huawei does stress that the results are for reference only and should not be used for definitive medical diagnosis.Another thing that’s impressed me about this watch is the battery life. Up until this point, I have only ever used Apple watches.But it used to frustrate me that I could barely get to the end of the day without the battery dying on me.The strap is strong and comfortable, with a sleek beige colourHuawei Watch D3, £399.99BUY HEREIncredibly, I’ve only had to charge this watch twice in the four weeks I’ve had it (I was on holiday for 10 days in that time and didn’t take it with me).Despite running all sorts of tests and programs on it, the battery life more than holds up.With typical usage, it can last for up to six days – making it a formidable piece of tech that you can rely on.I’ve also enjoyed a deeper analysis of how much sleep I’m getting – including how many times I woke up, my REM sleep and my breathing patterns while sleeping.And just like on an iPhone, you can sync this watch to your smartphone and get all your text notifications, plus use the device to find your phone if you lose it.The D3 is priced at £399.99 in the UK, but Huawei is offering a special deal for those who purchase early.Customers who buy the device between launch day and November 3 will receive 10 months of Bupa Well+ Silver health subscription, normally worth £200.That will provide you access to digital GP appointments, physiotherapy and mental health support.You will also get a £30 Amazon coupon to go with it.It’s very hard to fault the D3 given how comfortable it is to wear and how many different features it gives you.But the most important takeaway is that it’s a genuine healthcare companion.Especially for those of us entering our 30s, 40s and beyond, our health is becoming so important.The D3 simply helps you keep an eye on it, so you can focus on living better.FAQsIs Huawei D3 worth the money?At £399, this is definitely a premium product, but with the amount that’s packed into it, you can see why.Those who have previously splurged on an Apple Watch and want to switch things up might be interested given that most Apple devices are around the same price range.However, much of the cost is down to the state-of-the-art features found in the watch, with a focus on health and fitness.If you’re more into the techy stuff that the Apple Watch offers, this might not be for you.The bag used to measure your blood pressure is hidden beneath the elegant strapHuawei Watch D3, £399.99BUY HEREHuawei D3 key features: What can it do?The D3 comes with an array of features designed to keep users informed about their health and aware of how their body reacts to exercise.Huawei emphasises that any data provided by the Watch D3 is for informational purposes only and is not intended to replace a professional medical diagnosis.Here is a list of key features it offers:Blood pressure monitoring: The D3 comes with a bag hidden under the strap that inflates to take your readings.ABPM: The device can automatically take your blood pressure overnight and across a 24 hour period.ECG and SpO2: The watch can take an electrocardiogram to detect any arrhythmias and can check your blood oxygen levels.Dedicated BP workout mode: The D3 can monitor blood pressure before and after a workoutHost of fitness modes: More than 80 workout modes, whether you’re running, skiing or simply having a workout at the gym.Long battery life: Up to six days of battery life – though with regular ABPM tracking it decreases to one day.For more sports, health and fitness content and buying guides, check out our dedicated talkSPORT shopping hub.
