   Probably the best smartwatch if you have a Samsung Phone (or Android)
   Update after few weeks of usage – Everything I reported before is still same. But there is a way to get BP and ECG test on to watch by installing modified versions of Samsung health monitor. So there is a way of getting that to work unofficially.I have bought the 45mm BT version of this watch. This is my experience after using it for 2 days.Price – Reasonable. I purchased with the launch offer at 28k. It is relatively expensive compared to Android Wear watch options, but I think if you have a Samsung Phone, it might be worth it. I have Samsung Note 10 and Samsung works well with Samsung, but I think with the necessary apps installed it’ll work the same way on other Android phones.Android Wear vs Tizen: I previously had Fossil Explorist Gen 4 watch which runs on Android Wear. In my personal experience, Android Wear as an operating system needs a lot of work. The Fossil watch was unbearably slow, battery backup was very bad, thought it could do the normal smartwatch things, because of the poor battery, I couldn’t use it at all. I just kept the watch on Flight mode and used as a normal watch to display time. My experience here could be biased as I didn’t really use Android wear to the fullest. I used it for Navigation a few times, but for that to work, the same Google Maps app has to be open on your phone. It will just tether the content to the watch. On contrary, Tizen doesn’t really have Google Maps app or any equivalent navigation alternatives. So it may not be the best for Navigation. Otherwise, the OS basically looks like a modern Smart Watch – with widgets, notification area, quick control panel etc.The watch has an option called Automatic WiFi where it will connect to the WiFi in case it gets disconnected from the phone (Bluetooth). This is super useful. On Samsung phones, there is an option called Call and Text on other devices. If you are signed in with your Samsung account and this option is enabled, even when my phone isn’t connected to watch, I can still make and receive calls just using watch while it is connected to WiFi. This is such a great option, just like the LTE version, but on Bluetooth watch using WiFi.Health Features: The watch DOESN’T have ECG enabled in Indian units. They recently got approval in US from FDA but who knows what regulations are there in India and if it will ever come to this. The hardware required is there in the watch, just that Samsung has to get approvals and enable it through Software. Even last year’s Galaxy Watch Active 2 is waiting for this. So don’t get the hopes high about this. Other than this, it has Blood Oxygen tracking which works, Heart Rate sensor and automatic workout detection. There are a bunch of pre-set workouts in the watch that it can track. And it does a pretty good job. Using Samsung Health app on phone, you can get access to a lot more third party exercise tutorials.Sleep tracking is also available on the watch and it works great. It can precisely track sleep in my opinion and gives out detailed analysis of sleep pattern and efficiency. Once you connect the watch to phone via Bluetooth, all these data gets synced with phone and you can detailed overview on the Samsung Health app on phone.Battery: Battery lasts 2 days if you don’t have the always on display. If watch is always on to show time, it takes up a lot more battery. During these 2 days, I used it to track a lot of my exercises, sleep tracking, basic notifications and the battery easily lasted 2 days. But I had the always on disabled. There is a toggle on the watch itself through which you can easily turn this on and off to save battery when required.Miscellaneous: The watch band feels very cheap and light. Though it says leather, the leather band I have with Fossil watch feels a lot premium. This watch band even makes cheap plastic type of noise when you try to wear it. Otherwise, watch is pretty comfortable to wear. Also I prefer the way Fossil looks. This watch looks more like a fitness watch than a regular watch.So to end the review, following are the pros and cons in my opinion:Pros: Great battery backup – almost 2 days, easy to charge using any wireless chargers, has a tonne of features – you can check YouTube videos to know all the features available, works perfectly with Samsung phones, can connect to WiFi in case it is not connected to phone via Bluetooth and you can still make and receive phone calls. This works only with Samsung phones I think, so check about this if this is important.Cons: ECG doesn’t work yet, watch band feels very light and cheap, no proper Navigation app, lack of app support because of Tizen OS

   It’s a good watch if you have Samsung phone
   It works great sometimes it does lag but it’s manageable the display is bright the battery however is not so good but if you charge it regularly then it’s not a issue you can use navigation by using a app but proper Google maps support could have been better the bands feel cheap but you can replace it by other straps the mic is alos surprisingly good overall a good product if you want a smart watch with decent workout tracking

   After using 60 days
   I used watch for 60days..Battery:Performance wise everything is okay but battery drains with in 2 days if you’re using normal mode . There are three modes to use,second mode is power saving which displays time and notifications and third is watch mode which displays only time.With the third and second modes battery won’t drains quickly.Connectivity:You can connect watch through Bluetooth and wifi . And u can organise ur watch through galaxy wearable app or else u can organise directly through watch.For LTE , u should have either Airtel postpaid number or jio or vi.Health:ECG and BP are still not activated.But Oxygen level and pulse(heart beats) are availablePrice :Price is very high , i bought LTE 4G 41MM SILVER colourWatch strap is premium quality but after wearing for more hours intialy ,it is not comfortable but now it’s fine

   Excellent Formal Looking True Smart Watch3 by Samsung
   Excellent Android smart watch, money can buy. Accurate sleep tracking, accurate Spo2 reading but please keep the watch rightly on your wrist as suggested by Samsung, otherwise some reviewers like GeekyRanjit might mislead you by telling that Spo2 does not work on wrist. Spo2 reading is not a video game, it needs lot of accuracy and specific positioning on wrist. Hats off to Samsung for providing an accurate Spo2 measurement. Battery life is adequate and quite at par with any other truly functional smart watch. One and a half day for sure with moderate use and one full day with all functions on and active. ECG & BP will come soon to India after government formalities. ECG has come to USA recently.

   Wrist companion of phone
   Moderate size to my wrist , felt 45mm is slight bigger , weight is felt, vibration is moderate, leather strap is semi premium , call sound ,and answering is clear and audible without any distortions. WhatsApp messages are visible, I could pair with my samsung phone easily with wearable app and with health app. Walking is tracked and notifications can be seen both at phone and watch. So you wont miss your alerts and calls anymore . Many display dial faces are with app and you can even modify it custom . Good one,though pricy .

   Beautiful and customizable device. Sold me on the very idea of a smartwatch
   It’s a lovely device – well made, well designed and the rotating bezel draws attention like nothing else. If you have a Samsung phone, then the camera controls are an added bonus. Good battery life as well.Cons – No ECG tracking in India, O2 monitor is iffy and needs a lot of adjustment to work. However, getting a metal strap did alleviate this to an extent.

   Good smart watch for Samsung users and fan boys
   Premium look. Super crisp and clean display with wide array of colours. Speaker volume and sound quality could be better. Battery life is sub-par as the charge stands only for 2 days(my daily usage experience). Software management is excellent and well optimised. Activity tracking is a little inaccurate(especially for steps and running. Even waving your hand in the air also counts as a step😂). Overall a good smart watch
