FOSMET “R1” is a round smartwatch equipped with an AMOLED display, sapphire glass, Bluetooth calling, and sports modes.
It is designed to cover “broadly and shallowly” from daily notifications and calls to light exercise recording, and we felt it was a good choice for those who also want to emphasize the quality of the appearance.

Design and texture: Satisfaction for those who prioritize appearance

The FOSMET smartwatch with a black face and metal band displays 11:39 AM and September 7th
FOSMET's black metal smartwatch
Point
  • A luxurious appearance with a metal and sapphire glass combination
  • Fits both casual and business styles
  • For those who prioritize quality over lightness

The first impression of the R1 is that it “looks more expensive than it is”. The stainless steel exterior combined with sapphire glass gives it a calm and luxurious feel. It looks good in everyday use and doesn’t feel out of place with a suit.

However, because of the metal construction, it has more presence than lightweight resin models, and some people may feel it is heavy after wearing it for a long time.

Ms. Gadget

Does it stand out in both work and private life?

Mr. Gadget

Yes, the calm design makes it easy to match with a wide range of scenes. However, it may be a bit heavy for those who prioritize lightness.

Screen visibility: The strength of AMOLED

The FOSMET smartwatch with a black metal band displays 11:39 AM on September 7th

The 466×466 pixel AMOLED display has clear characters and vivid colors. It has high visibility both indoors and outdoors, and also 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. Gadget

AOD compatibility is great!

Mr. Gadget

Well, just be careful as it will drain the battery.

Battery and charging

The R1 is officially advertised as lasting 7-14 days with normal use. Charging takes about 3 hours to complete, and it can last up to 25 days in standby mode.
However, battery life will vary depending on the number of notifications, screen brightness, and frequency of exercise measurement. Those who frequently use notifications and workouts may find the actual battery life to be shorter.

Mr. Gadget

I measure my heart rate frequently and turn on AOD, so my experience is about two days.
Battery life depends on how you use it, but don’t expect too much.

Calls and notifications

It supports Bluetooth calling, allowing you to make and receive calls without taking out your smartphone. It’s convenient to finish short calls while doing housework or commuting.

Health management and sports: A design that covers a wide range

It is equipped with basic health management functions such as heart rate, blood oxygen, stress, and sleep monitoring. It also has over 100 sports modes, widely supporting running, walking, and strength training.

However, it does not have a built-in GPS function, so you need to connect it to your smartphone to record your exercise route. Also, the measurement values are for reference only as it is not a medical device.

Mr. Gadget

Well, these are features that are common in most smartwatches these days.
This smartwatch prioritizes the metal appearance, but it still supports these features.

Waterproof and durability: Daily resistance of IP68

It is IP68 waterproof, so sweat, rain, and water splashes during hand washing are no problem. The sapphire glass is scratch-resistant, which is reassuring for everyday use.
However, use in hot water, seawater, or saunas is not recommended, so be careful depending on the usage environment.

App

The device screen of the smartwatch management app displays 6:20 AM and Sunday, September 7th, with a battery level of 86%. It also shows the watch face market and settings menu.
The smartwatch watch face selection screen displays various designs showing time, steps, and other information.

FOSMET R1 uses a smartphone app that allows you to manage detailed data and settings by connecting to the device.
Many inexpensive smartwatches have a problem with the usability of the app, but the FOSMET R1’s companion app is simple and intuitive.
You can choose from a wide variety of watch face designs and easily check your health data.

A perfect watch for everyday use

The “FOSMET R1” is a smartwatch equipped with the necessary functions for daily use, such as an AMOLED display, sapphire glass, and Bluetooth calling.

The body has a luxurious design with a metal exterior and is easy to match with both suits and casual wear. It is highly satisfying for those who prioritize appearance, but it may feel heavy for some people.

The battery lasts 7-14 days with normal use, but it will be shorter if you use AOD or many notifications.

It does not have standalone GPS or advanced exercise analysis functions, but it is sufficient for those who mainly use it for health management and light exercise logging.
