I have had this watch for about 4 months now. At first, I was quite hesitant about buying it. In the end, after studying the competition thoroughly, I decided to go ahead with the purchase.
I exercise 4 to 5 times a week, either at the gym or running outdoors. I can say that its measurements are accurate (heart rate, oxygen, distance, etc.) as I have verified them with external sources and the results are similar. That is, the heart rate and oxygen levels have a deviation of (+) or (-) 1 unit. As for the distance measurement outdoors, thanks to GPS, it is very stable. If there is any deviation, it would be during indoor running on a treadmill, with a maximum deviation of about 2%-3%.
The screen is very large and allows for reading messages and emails with good brightness.
The battery life for the Apple Watch is quite good, lasting about 2.5 to 3 days, including two 90-minute workouts each. If it lasted 5 days, it would be simply perfect.
It has a large memory for storing apps and music.
One main reason that made me choose it is its durability against impacts. I couldn't have a product that I would have to worry about breaking with every intense activity.
Certainly, the reason for purchasing it is not only for the measurements during sports activities, but also for serving daily activities. Personally, it helped me in setting important notifications (messages and emails) to appear on the watch, while all other notifications remain only on my phone. This way, it helped me decide whether I should pay attention to each phone notification or not, significantly reducing the time I spend looking at my phone screen and getting distracted by other apps. It greatly reduced the screen time of my phone.
The response with the iPhone is excellent. The call quality is very good, and the ability to reply to messages with dictation is very convenient. There are many apps available in the App Store for users to customize it according to their personal preferences and needs.
It is a very good solution for someone who is involved in activities and wants it to serve them in their daily life with some functions for their work. Although it leans more towards being a smartwatch due to its apps rather than a sports watch. Perhaps a more demanding user in terms of workouts may not feel satisfied as they would need to charge it more frequently.
It is more expensive than the competition with other brands, but I consider it a very good choice for iPhone users. In my personal opinion, it has helped me have a more productive daily life, combined with the quality monitoring of my sports activities, without the fear of it easily breaking like other watches from the same brand, at least.
