Withings ScanWatch Horizon – Hybrid Smart Watch with ECG, Heart Rate, Oximeter - 30 Day Battery Life - Smart Watches for Women, Smart Watch for Men, Fitness Tracker - Android & iOS

Purchased to replace Withings HR Steel. Includes both built-in Oxygen Sats and ECG compared with the HR Steel. I have confidence in the Scan version of this health monitoring watch. The watch face has a minimalist analogue design with a large circular digital display. Functions are selected via a revolving & push to select winder button on the right edge (the HR Steel version has a push to select only button). The display on the Scan watch is significantly larger than that on the HR Steel and is used effectively to indicate the ECG and O2 Stats monitoring. The watch has standard sleep monitoring functions and can sense sleep apnea due to the O2 Sats continuous monitoring while monitoring sleep. The watch also continually monitors ECG and will report any Atrial Fibrillation (AF) events encouraging visits to A&E or GP to investigate. The mobile App (Android & iOS) Health integrates data (read and write) with Android and Apple Health systems. The App is adequate for monitoring health parameters but could benefit from refurbishment/upgrade as it feels rather basic and lacks sophistication. I have a number of Withings health monitoring devices such as BP monitor, smart weighing scales & thermometer, which are all well designed and feel accurate (due to the specification rather than actual comparison with professional equipment), a perception which extends to the Scan watch. The Scan watch is an excellent companion ‘always on’ health monitor and could potentially save your life given the continuous AF monitoring.An almost eccentric feature of Withings analogue health watches is the analogue Step indicator dial which shows the percentage of target daily step count completed. It provides a very quick indicator of step count compared to Smart watches which may need the user to use multiple button pushes to display this data.Compared with Smart watches the Withings Health Scan watch’s superb battery life with over a week between charges (compared with daily recharge requirements), on top of which the charge time from <5% residual charge is in the region of 2-3 hours. The watch charge stand is not as elegant as, say, Samsung’s vertical Galaxy Watch charge stand but is magnetic and relatively easy to use and orientate.The Withings Health Scan watch is quite expensive compared to Android Smart watches (not Apple Watches!) and the Withings HR Steel but it is well worth the money with the continuous ECG and O2 Sats monitoring - it might save your life….

This watch is gorgeous and super reliable. I’ve been using it for over a year and the battery life is still great. I wear it every day and the battery lasts more than a month for me (auto wake is off). I love how discreet it is and the fact it looks like a stylish unassuming mechanical watch when the display is off.The software is fine, and there are updates that really improve the watch once in a while. It tracks a good range of data and has great integration with Apple Health. The watch UI is fine and the app is full of features. The ability to see trends over the day, weeks and months is really nice.In terms of quality of data, it probably isn’t as accurate as other trackers out there in terms of step count, HR and sleep monitoring. One of the reasons the battery life is so good is it only measures HR every 10 minutes if not in workout mode. However if you don’t care about the absolute accuracy and are are happy with a good idea of data trends, the Scanwatch is more than good enough.This watch blows away the competition in terms of style, reliability and battery life. I am super happy with this and would absolutely recommend!

I've had a few wearables over the past few years, but always very conscious that they looked obviously like a piece of tech - ie a Fitbit or a Xiaomi Mi band where the entire face lights up.Main purpose of buying is 1) to hold myself accountable for fitness, 2) to have notifications discretely provided and 3) tracking sleep.Best part is that I often forget that it is a piece of tech that is supposed to provide notifications - I've set the long-press of the button to quickly activate Do-Not-Disturb mode, which does accidentally activate a few times it looks like which can be a negative for a lot of people. However, the UX is a bit confusing especially when you have to scroll to go to the 'back' option.The sleep-tech seems accurate based on my recollections of wakign up - but seem relatively binary between 'good' and 'bad' sleep. A bit more integration and smarts between heartbeat and sleep would be nice.I'm pleasantly surprised there is a vibration motor for this which I did not realise in my research - however there's no ability to customise the haptics on how intense it is. Implementation is also a bit iffy - the two sequential buzzes for 'goal reached' for example come as two different notifications spaced around 20 seconds apart, which is enough for me to read the first notification, put my wrist down, then it buzzes again to make me raise it once again. I'm also concerned when it vibrates but isnt on my wrist, but on a hard surface - a short check whether the Scanwatch is actually being worn before vibrating would be useful and probably saves battery life.Battery life in the short term is fantastic - I've charged maybe five times in the past two months but definitely could have done less. If you turn on DND and turn off quick-look, I'm sure battery life could hit 3 weeks with ease. However, I'm not as happy with that the magnetic charger has a USB-A connection at the other end, which should definitely be USB-C.Seem's relatively sturdy - I've hit this on surfaces a few times because its the first time wearing a watch for a very long time. Yet to see any scratches but it has only been a few months. However, noticed that the silicon watchstrap very quickly accumulates sweat and a noticable smell. Will likely swap this out for non-silicon at one point.Looks are fantastic, although in poorly lit environments, the silver markings on a white watchface can be hard to read. I'd expect different watchfaces might have different experiences, particularly silver on black. Surprised that there is not a watchface with black markings on white. Haptics on the knurled knob could also be slightly improved, but otherwise is easy to manipulate.Overall, very happy with this purchase.
