FOSMET R1 Review & Usability
Design & Texture: Satisfaction in aesthetics


- Luxurious appearance with metal and sapphire glass
- Fits well with both casual and business styles
- For those who value quality over lightness
The first impression of the R1 is that it looks more expensive than its price tag. Combining a stainless steel exterior with sapphire glass, it has a refined, luxurious feel. It doesn’t look out of place for everyday use, nor when paired with a suit.
On the other hand, because it is made of metal, it has more presence than lightweight resin models, and some people might find it heavy when worn for long periods.
Ms.GadgetsDoes it look out of place at work or in private settings?
Mr.GadgetsNo, the understated design makes it easy to match with a wide range of scenes. However, it might be a bit heavy for those who prioritize lightness above all else.
Screen Visibility: The strength of AMOLED

The 466×466 pixel AMOLED display renders text sharply and colors vividly. It has high visibility both indoors and outdoors and supports Always-On Display (AOD).
However, enabling AOD increases battery consumption, so those who use it frequently should be aware that the charging interval will be shorter.
Ms.GadgetsAOD support is great!
Mr.GadgetsWell, just be careful because it will worsen battery life.
Battery & Charging
The R1 is officially rated to last 7–14 days with typical use. Charging takes about 3 hours, and it can stay on standby for up to 25 days.
However, battery life varies depending on the number of notifications, screen brightness, and the frequency of exercise tracking. For those who frequently use notifications and workouts, the actual battery life will likely be on the shorter side.
Mr.GadgetsI measure heart rate frequently and keep AOD on, so in my experience, it lasts about two days. It depends on how you use it, but I feel you shouldn’t have overly high expectations.
Calls & Notifications
It supports Bluetooth calling, allowing you to make and receive calls without taking out your smartphone. It’s convenient for handling short calls while doing housework or on the move.
Health Management & Sports: “Wide coverage” design
It includes essential health management features such as heart rate, blood oxygen, stress, and sleep monitoring. Furthermore, it comes with over 100 sports modes, supporting a wide range of activities from running and walking to strength training.
However, it does not have built-in GPS, so smartphone connectivity is required to record exercise routes. Please note that since this is not a medical device, measurements should be treated as reference values only.
Mr.GadgetsWell, these are features found in almost every smartwatch these days. Even though this watch focuses on a metal design, it at least supports them.
Waterproof & Durability: Daily IP68 resistance

It supports IP68 waterproofing, so exposure to sweat, rain, or water while washing hands is not an issue. The use of sapphire glass provides scratch resistance, which offers peace of mind for daily use.
However, use in hot water, seawater, or saunas is not recommended, so please be cautious depending on your environment.
App


The FOSMET R1 can be used with a smartphone app that allows for detailed data management and settings by connecting to the device.
While the difficulty of using apps is a major pain point for users of many inexpensive smartwatches, the companion app for the FOSMET R1 is simple and allows for intuitive operation.
You can choose your preferred style from an abundance of watch face designs, and it is designed so you can check your health data at a glance.
| Item | Details |
|---|---|
| Health Data Management | Real-time display of heart rate, SpO2, sleep data, etc. |
| Notification Settings | Individual settings for calls, messages, and SNS notifications |
| Watch Face Customization | Abundant designs |
| Device Search | Find the location of the smartwatch with sound |
| Firmware Update | Apply updates for functional improvements and new features |
