I worked hard to get the Apple Watch. I had high expectations for it and I bought it. I could mention quite a few positives, but the PRICE and the BATTERY are really THORNS. A-THORN, which overshadow many other positives. I have thought many times about selling it and going back to my small and beloved Xiaomi band (6). If the band 7 comes out and I like it, I would replace it without a second thought, to be honest. But let's not forget the dream I bought it for after I worked hard and treated myself. If you read this, I would love your opinion on anything or your own experiences! Tough times for princes and expenses amounting to half a salary (in the best of cases).

+ Perfect synchronization even with iPhone 6s.
+ Amazing screen, perfect colors.
+ Sturdy device.
+ The speaker for the alarm clock.
+ Strong and nice-feeling vibration.
+ Because you can download third-party apps, you can also download a game to pass the time.
+ Let's not kid ourselves: beautiful, elegant, luxurious.
+ You can respond with voice dictation to messages. And you can talk with the watch if you want to feel like James Bond for 2 minutes. Of course, this helps while driving. Personally, I don't find responding with the watch very convenient anyway.
+ Many activity modes.
+ Nice lens.

- The price!!!!
- It doesn't recognize when you stop exercising. What the hell, for €350 I would want this feature.
- Coming from the Mi Band 6, it annoys me IMMENSELY that to track your sleep you have to activate the sleep mode and it doesn't recognize it automatically. If you fall asleep without doing it, you lose your measurements. Also, the information from "Health" about sleep is at least disappointing, especially compared to the Xiaomi app.
- Battery, battery, and BATTERY! In 6 months it dropped to 96%. With everything activated, I would say it lasts about 1.5 days. With many workouts and many measurements, at most 1 day. The battery is a joke. I like that it has hiking for measurement. If you go to the mountains for a 2-day hiking trip, the watch is useless. Unless you want to carry a charger and power bank, then I give up. In the summer, I go on all-day hikes and we walk for 8-10 hours. If you track for so many hours, forget about the watch! It has slept half the day.
- Generally, the "Health" app. I find it chaotic, incomplete, and difficult.
- It doesn't have stress measurement.

• Guys, I don't know if the measurements are good. I think they are generally. The steps it counts daily, let's not kid ourselves, are not accurate. No watch is accurate. You fold clothes and it shows 100 steps, you know what I mean.
• Also, if you set automatic measurement for oxygen, heart rate, etc., it measures them infrequently compared to Xiaomi. For example, it might measure every hour. The Mi Band measured every ~5 minutes, for instance. Not that such frequent measurement is necessary, but I point it out.
• Okay, quite a few faces. Quite elegant, some playful. But you don't have countless options.
• Towards the end of the day, if I still have battery, I like the always-on feature on my wrist. It makes the watch even more beautiful!
• Guys, I'm afraid to put it in the bathroom. It says waterproof for showering, but I don't want my €350 to drown. You don't worry about the Mi Band at €30. Plus, I took a bath in the Aoos River for hours with it and it didn't suffer ANYTHING!

Guys, in general, but personally, any smartwatch has A LOT of things. BUT... what do I need the photos for on my watch, for example? Maybe a good smart band, with basic-daily-quick applications (weather, altimeters, measurements, music...) would be enough! This allows for a lower price, a larger battery, and in this, Xiaomi, HUAWEI, Honor, and Amazfit have won.

At first, until I received it, I had doubts about whether it would be worth so much money, but really, as soon as I tried it... Every trace of doubt vanished! It is exceptional! You can do almost everything from your wrist! Music, Calls, Messages, Fitness Tracking, Heart Rate Monitoring, Sleep Tracking, and many more! It has countless Watch Faces for every taste and age. Also, it is waterproof, so you can bathe with it and wash your hands without worrying that it will break, and it even has a function to remove any drops from its speaker. Essentially, it is a jewel with a built-in Smartphone. Its battery lasts one and a half to two days with regular use, and a full charge takes less than an hour. (I haven't measured exactly) Its operating system is very user-friendly and every movement you make on it is very smooth, something that unfortunately is rare in Android Smartwatches. The only "flaw" of Apple Watches is that they are not compatible with Android devices, only with Apple. In my opinion, if someone is looking to buy a Smartwatch, the Apple Watch is the best they can get.

In 2017, I made the choice to switch from the Android space to iOS.

Initially, I was a bit hesitant, but along the way until today, it made me dive even deeper into the Apple ecosystem with several of its products.

The latest product was the Apple Watch series 6, which as I mentioned before, was a one-way street for me, as this, like all the other products in the ecosystem, integrates perfectly with each other!

On the positive side:

1: Very good and quality construction materials
2: Measurements are quite accurate with minimal deviation
3: Clear screen with very good customization
4: Excellent interaction with all Apple products and with the use of iCloud, everything is instantly synchronized between them
5: Many times I caught myself using my smartphone less and less, as I see most notifications on the Watch and manage them better by evaluating their urgency in terms of response or whether to waste time looking at them
6: Excellent fitness tracking with many parameters and options, as well as competitive challenges that you can do with friends who also have an Apple Watch, giving you an extra motivation and encouragement to exercise in the form of a game
7: Health features (Electrocardiogram & blood oxygen monitor) which, as Apple states, do not replace medical monitoring and advice, but provide you with some information that, if it causes you concern and reflection, you can immediately consult a specialist doctor
8: Fall detection function that, in the event of an accident, notifies emergency contacts that you have registered after a short period of time

On the negative side:

1: It could have had automatic sleep tracking instead of needing to download a third-party app from the App Store, although there are several reliable options available
2: Although I haven't had any accidents so far, the construction of it worries me that with a fall or impact, mainly on the screen, a scratch or even worse, a breakage could occur, making the use of a case necessary in order to feel safer, especially if one is careless or engages in intense physical activity

Overall, if you have an iPhone, I believe that this smartwatch is a one-way street.

I am not an expert on smartwatches. It is the first one I bought after 2 Huawei smartbands. Night and day in terms of functionality and usability.

There are many positives that I won't mention since they are mentioned on all sites and reviews. One positive compared to the Apple Watch 5 that a friend has, is that the 6 lasts almost 2 full days of use (instead of 1 and something) with notifications from messenger, viber, email and responding to them through voice dictation, with speech on some calls due to inability to access the phone, but without any particular effort other than walking half an hour a day for various tasks.

A positive thing I will mention is that the screen is incredibly durable. I'm used to not caring about hitting my hands with smartbands, etc., scratching them without caring, and it's difficult for me to adjust to wearing a watch that costs 400+ euros. I've hit it several times against walls, desks, doors, etc., but after cleaning it well and looking at it carefully from an angle, there is absolutely nothing visible. Wow.

As for the negatives, one thing that impressed me apart from the battery, which although it lasts noticeably longer than the 5, is much lower compared to Samsung or Huawei smartwatches that offer at least 5 days, is the absence of sleep analysis. A huge negative if you consider that even "cheap" bands of 30-50-70 euros have this feature and it seems to be quite accurate. The only thing it shows you is the duration of sleep. There are apps that offer it, but to get close to the analysis that, for example, Huawei Health does, you have to pay a subscription of 30 euros per year. Simply unacceptable.

Another negative is the inability to choose the default language of each application or at least the input language. I also include the fact that you can't add/remove some quick replies to fit your needs and the way you communicate.

Mainly for the sleep analysis issue, 4/5 stars.

EDIT: One year later, after 4 days. The watch turned off and never turned on again, after an endless boot loop. Luckily, it's still under warranty. Replacement. I hope the new one lasts longer than a year.

Owner of the Apple Watch 6 here for 2 months.
It is a device with many capabilities which is very useful mainly for sports and health reasons. It measures heart rate and blood oxygen levels at regular intervals. It can detect if you have breathing interruptions during sleep as well as heart arrhythmias.
I admit that since I bought it, I have become more active because when you see your measurements on a daily basis, you take care to improve them. You can set daily goals and it informs you about their progress. Its measurements are quite accurate and it syncs perfectly with the iPhone. The sleep tracking is also very good and the sleep program helps you maintain a consistent schedule.
Another nice feature is the vibrating alarm without sound to not disturb those around you.
Also, if you take it off your wrist, it requires a passcode to unlock and of course, you can locate it with Find My.
The battery is quite satisfactory as it charges in about 2 hours and with theater mode, it can last up to 48-50 hours. Even with heavy usage, the battery lasts at least 18 hours.
The package includes two straps that cover all hand sizes.

On the negative side, I would say that the main drawback is the fact that it is not a 100% standalone device. Some of its functions are available even without having the iPhone near you, such as measuring blood oxygen, ECG, step counting, etc. However, for many useful functions like making calls and sending SMS, you will need to have your phone nearby (<30 meters). These functions are available in the cellular version which unfortunately is not available in Greece.
It does connect with Airpods, but if you want to listen to music when you go out for a run (streaming from Apple Music or Spotify), you will have to carry your iPhone. Even to listen to downloaded playlists from Spotify, you will need to have your phone nearby.
The blood oxygen measurement is not very accurate as sometimes it can measure 99% oxygen and the next minute 93%.
If you have the Apple Watch 5, I believe that it is not worth the upgrade and it would be preferable to buy an oxygen measurement device for less than €30 which will be more accurate.
