Brown leather is apt for formals and Black silicon is great for casuals.● DISPLAY ●--------------# It sports 1.39" HD AMOLED display which gives crystal clear output.# The display is Round with Vibrant colours and Bright Light (Adjustable).# Has Adjustable Backlit for better visibility and it also sports a Sensor to Auto adjust the brightness.# Its very responsive and has Awesome readability in direct sunlight as well.# It has awesome Always ON Display which can be customized as Digital or Analog.● FEATURES ●----------------*It has 5 main options namely Notification menu, Toggle Menu, QUICK access, Sports Mode & Main Menu.# In the Toggle Menu, there DND mode, Display mode, Find my phone, Alarms & Settings.# Notification menu is at the bottom and shows all the notification of the connected smartphone.* You shall get ONLY Notification alerts from almost all the apps (i.e. you can Read the message), but Can't Reply.# It also has Phone calling feature, via which incoming call can be attended or calling can be dialed from watch when connected via BT. And calling quality is surprisingly good.# Swipe Left or Right to get Quick access. It has Widgets like Weather Forecast, Heart Rate Sensor, Stress Mode, Music Player, Health data.● Sports Mode -->============* It activates by pressing Dedicated Sports button placed at the bottom.* There are 16 Main Modes in fitness App ranging from running, cycling, Swimming etc.* There's Voice Tech which notifies as workout starts, paused, ends, etc which is very unique and practical.* It tracks the data using GPS and Heart rate sensor. I used Walk and "Other" option daily and I must say that its very accurate. The GPS works accurately measuring the distance and speed with maximum accuracy. Heart Rate sensor is very accurate and measures the heart rate continuously. All the stored data can be easily accessed from watch directly and can be Exported to phone or Mail.* I noticed it to be Most accurate data till date.● Watch Faces ->===========* There are 14 watch faces inbuilt. Watch faces are quite impressive and has nice details.* It supports installing 3rd party watch faces as well, so this section is covered well.* There's setting available in few watch faces for colour adjustment and other stuffs.● Sleep Tracker & Heart Rate Tracker :-============================Accuracy of Huawei GT v1 is carried on to this watch as well. Its Most accurate in terms of sleep tracking as well.It can track Night sleep as well as DAY TIME NAPS accurately, which is NOT available in most of the watches currently.All the Data can be accessed from Watch itself or from Smartphone.It has also got Sedentary Reminder which reminds if you are sitting in one position for Longer period.Heart Rate sensor is also very accurate, rather the most among all. It tracks continuous rating seamlessly.Best part about HR sensing is, it is coupled with motion sensors, so when watch is lying on the table, it DOESN'T keep on tracking HR reading, thus saving Battery.*Even this feature is not available in most of the other watch yet.● MAIN MENU ●-------------------* It can be accessed using Dedicated Top button.You can access other features like Calling, barometer, compass, breathing exercises, timer, alarm, etc via it.●● BATTERY PERFORMANCE ●●-------------------------------------# It takes less than 120 minutes to charge device from 0 - 100%.# With HR sensor on 24hr mode + TruSleep ON + Bluetooth ON 24hr + 1hr Fitness tracking gives 7 days of backup.# With HR sensor on 24hr mode + TruSleep ON + Bluetooth ON 24hr gives 8-9 days of backup.# With Bluetooth connected 24hr and normal tracking gives 10-12 days of backup.# With Smartwatch in Offline mode with normal tracking gives over 14 days of backup.### All the above Backup Times are REDUCED to Half when Always ON Display is Turned ON #### When AOD is OFF battery backup is just insane for a smartwatch, but even with AOD ON its still the Best among any watches currently available in Market.●● CONS ●●--------------There's no 3rd party app support yet, but this is in turn facilitates the Ultra smooth functioning of the watch.●● COMPARISON with Galaxy Watch ●●----------------------------------------------# I am comparing it with Samsung Galaxy watch because both are very similarly priced at times,especially during recent sale period.1. Design section -Both watches have almost same Design and shades, except Galaxy having rotating bezel which I personally like.But Overall comfort is better with GT2.Winner - GT2.2. Display section -Both have almost similar resolution display, with GT2 being slightly bigger and better.Touch response is also same.Winner - GT2.3. Pedometer & Workouts -Pedometer accuracy is almost same on both the bands.But there are twice as many workout modes on Galaxy watch compared to GT2.Winner- Galaxy watch.4. HR Sensor -Both the watches have 24hr HR sensing, but GT2 has smart sensing which saves ton of battery.Level of Details are immaculate in both of them.Winner - GT2.5. Sleep Tracker -Both the watches Record Day & Night time data, but Sleep tracker of GT2 is undoubtedly much more accurate.Data Representation is also better in GT2.Winner - GT27. Battery Backup -Battery backup is indeed better on GT2, more than double compared to Galaxy.Winner - GT28. Accessories -Replacement straps are easy to access on Both the watches, but 3rd party accessories are cheaper for GT2 compared to Galaxy watch, least when you buy from India.Winner - GT29. Features -Features are even matched on both the watches.But Galaxy has access to app store, which is limited again.Winner - Galaxy watch.10. Price -Finally GT2 is more than 3000 rupees cheaper than Galaxy watch.Winner - GT2.Final Result - Huawei GT2 - 8 & Galaxy Watch - 2P.S. Don't even think of comparing GT2 with any other smartwatches under Rs.20k segment, as none of them could match it currently.Also some users may have different opinions for the sections like Design, Display & Features, but rest of the 7 sections are Facts based, so kindly note that.●● VERDICT ●●------------------Its indeed a impressive overall smartwatch in current market. Has almost all the features one needs. GPS and HR monitoring is Precise and with battery life of over 8 days its just a charm.So if you are fine with in-built interface & features, then certainly go for it. Its best deal in the current market.Having tried almost all the smartwatches in this price segment and comparing it straightaway with Galaxy watch, its no brainer for anyone with said budget to go for GT2.Hope this helps you make sound decision.
