The most advanced health monitor on a smartwatch
The watch that watches out for you. Galaxy Watch3 combines smartphone-level productivity and leading health technology in one premium and classic device. Our most advanced Galaxy watch yet, Galaxy Watch3 helps you effortlessly manage your life and health — putting your well-being in your hands.

The only smartwatch with precision rotating bezel for app navigation
Take your pick of two sizes, 45mm or 41mm, each with a face you won't soon forget. Available in premium Mystic Black, Mystic Silver, and Mystic Bronze hues, the elegant design is outlined in a unique rotating bezel for a look that works around the clock.

Beauty with smarts to match

Take your health into your own hands, with your wrist

Monitor and track your blood pressure
Check your blood pressure via the Samsung Health Monitor App without regularly needing a cuff. Before first use simply calibrate with a cuff, then smart sensors measure your blood pressure through pulse wave analysis as you wear it. Check it daily to track trends and get reports right on your phone

Breathe easier with built-in oxygen measurement
Galaxy Watch3 uses red LED and infrared rays to estimate your SpO2 levels, or the amount of oxygen in your bloodstream. Because this oxygen saturation is directly linked to physical performance, you can use Galaxy Watch3 to push your routine to the next level

Fall detection that won't fall down on the job
Explore fearlessly. Galaxy Watch3 automatically detects hard falls with its enhanced accelerometer, sending an SOS to your emergency contact with your location.

Get a better night's sleep
Galaxy Watch3 records your REM cycles, deep sleep, and total sleep time to score and help improve the quality of your rest. Samsung partnered with the National Sleep Foundation to include educational content and sleep tips right on your device, to help you understand and improve your sleep.

Improve every stride
Galaxy Watch3's running guide lets you keep pace as you get tips on the go. The advanced algorithm analyzes how you move to help improve your form and prevent injuries. You can even measure VO2 max values and keep up with your daily, weekly, and monthly performance right from your phone.

Smartphone-level power is now within reach

Keep the conversation going
When you get a new text, Galaxy Watch3 shows your chat history so you can effortlessly follow the conversation. You can also see images without an extra tap, making it even easier to keep the mood going while on a run.

Add a little context with smart reply
Stay connected with others even on the go – and without fumbling to reply. Galaxy Watch3's smart reply analyzes texts and photos you receive and gives you suggested replies, supporting different categories that include food, celebrations, selfies, and more.

More fun in your messages
Bitmoji stickers open up fun new ways to communicate. Personalize your Bitmoji to look just like you and use Bitmoji stickers to jazz up the way you talk to family and friends.

The beat goes on and on
Your music doesn't stop as you go from one device to another. Play Spotify on your Galaxy Note20, then open it with the Spotify app icon on your watch face to easily switch songs from your Galaxy Watch3. Or you can even touch and hold Galaxy Buds Live to get lost in the music.

Team up with other apps
Put together a team of Galaxy Apps to join you and your phone in your day-to-day. Find your phone and see your phone's photos from your watch, or switch between devices to control your music and check reminders. The perfect partners are all on your wrist.

Leave your phone at home
Go out for new experiences without the weight of your phone. You can still call, stream, and check your steps — all from your watch. Disconnect from your phone, while staying connected with life.

Samsung Galaxy Watch3 SM-R840 Reviews

  • Galaxyスマホ持ちにはベストな選択肢
  • by John Smith / 17 December 2020
  • 12月4日にポチッと購入。 3〜4日でヤマトにて配送完了。 開封してセッティング開始直後、選べるロケーションが中東地域のみで焦る… でも日本語は表示されるし、あとでどうでもなるだろうとロケーションはUAE選択。 (箱を見るとUAE向けの商品と判明w) 手持ちのGalaxy S10とペアリングさせると難なく認識。 そこから使用言語も日本語に変更可能でした。 すぐにファームウェアの更新があり、今に至る。 商品は質感も高く、特にダイアルリングでの操作性が秀逸。 Galaxy S10でのメッセージやリマインダー、通話など一通りコントロール可能で バッテリーの持ちも新品だからか、あまり使わなければ3日くらいはギリギリ行けそう。 その他心拍計などの機能もそこそこ正確な数値を表示しているので日々の 生活にはなかなか重宝。 また、サードパーティーの付属品(バンドやリング・ケース保護カバーなど)は国内の A○○zonで豊富に売っているので好みで揃えられる。 ただ、唯一の弱点は電子マネーがSamsung Payしか対応していないので、 電子マネー系重視の方には向かない。
  • とてもいい!

  • galaxy gear s3を使っていましたが、壊れてしまったため買い替えです。 国内販売されるのを待てずにこちらで購入しました。 バッテリー持ちはgear s3の倍程度になり2日弱もちますが、妻が使用しているhuawei watch gt2には遠く及ばずですが、サードパーティアプリを使えるので自分色にできます。 今は自作ウォッチフェイスで遊んでます! 楽しい!
  • つかいやすい!

  • 購入から5日程度で届きました。 日本で購入するよりもやすく、また使いやすいです。
