As the owner of the watch for about 2 months, I have the following to say:
1. Premium construction from the case to the strap. The high-quality and bright screen enhances the overall image, and you won't encounter any issues with it.
2. The touch function will never let you down, as it responds instantly and accurately. This is evident in all its functions, especially the keypad for calls, where many smartwatches fall short.
3. You can install applications from the playstore, such as Strava, and track your workouts there.
4. The battery can last from 2 to 10+ days, depending on the mode you have it on (power-saving or smart mode). Personally, I use the smart mode with two power-consuming functions disabled: always-on display and respiratory assessment (which measures breaths and snoring, estimating danger). With these settings, the battery lasts around 5 days, including 2-3 workout recordings. I have also disabled automatic workout tracking. It requires some exploration in the settings menu to find what you need and disable unnecessary battery-consuming features, such as long-press text magnification, permanently larger font sizes, and more.
5. It is waterproof, as I have worn it in the shower (not with hot water) and even in the sea. However, be cautious with hot water and make sure to rinse it after being in the sea.
6. It comes with several pre-installed watch faces, and you can also find many free or paid ones from other developers. Additionally, you can find many affordable straps on well-known websites from China.
7. It is comfortable, lightweight, and adequately sized on the wrist, as seen in the photos. I would have preferred it to be slightly larger (coming from the Garmin Fenix series with a 51mm diameter), but this is subjective. The two buttons can be customized to activate almost anything with a single or double press.
8. It continuously records heart rate and blood oxygen saturation. It also provides a comprehensive sleep analysis with detailed information. It offers workout tracking and energy-saving features. It measures barometric pressure, altitude, stress, has a compass, maps, NFC for payments, and more.
9. The screen is made of sapphire crystal with a 2.5D hardness and MIL-STD-810H military-grade certification. It works seamlessly without ever disconnecting from my OnePlus 12, as well as with the OnePlus Buds 2 Pro. The accompanying mobile application, OHEALTH, is user-friendly and provides ample information and explanations.
10. Charging is very fast, taking around 60 minutes to go from 0 to 100%.
Areas for improvement:
1. The round button on the watch is rotatable but doesn't serve any specific purpose, such as scrolling through menus. OnePlus claims it was designed this way for durability against impacts.
2. It does not have an electrocardiogram feature or measure blood pressure, which some users may desire. Additionally, it could include a fall detection sensor and notification system, in conjunction with other parameters, to contact a chosen emergency number. However, all these additions would increase the cost of ownership. Furthermore, you cannot view photos in messages, only the text.
In general, it is a good smartwatch that outperforms the competition due to its build quality and battery performance. The price, around €270, is good for what it offers. The exact rating I give it is 4.6/5. I hope I helped potential buyers by sharing my experience as objectively as possible.
