Glance at your wrist for heart rate, sleep, steps and incoming calls. The 1.72-inch colour touchscreen makes every number easy to read, and the matte silicone strap keeps it comfortable from the desk to the gym. Pick black, white, rose gold or a matching colourway and wear one watch from morning to night.
Large-screen smartwatch that tracks health metrics and stays connected, in a style to match any colourway
- tracking heart rate and sleep without a separate device
- monitoring blood pressure readings on the wrist
- seeing notifications and controls at a glance
Track your health and stay connected from your wrist
Tired of guessing how you slept or missing calls while your phone is buried in a bag? This 1.72-inch smartwatch puts heart rate, sleep and calls on your wrist, in a colour to match your day.
Everything you need, on a screen you can actually read

A screen you can read at a glance
The colour touchscreen shows steps, kcal, the date and the day of the week on the watch face. Notifications stay readable at a glance, so you know what needs a reply before you lift your arm. The screen is large enough to be useful, not just decorative.

Health data, right on your wrist
Heart rate and sleep monitoring run from the watch itself, and the blood pressure screen shows a 168/68 mmHg reading with its timestamp. Treat the blood pressure figure as a trend check rather than a clinical result, and keep a proper cuff for anything you need to act on.

Stay connected, hands free
Bluetooth calls come through the watch, and music and sports modes sit one tap away on the touchscreen. Pair it once with the companion app and your phone can stay in your bag on the commute. If you want a better fit for the way you already wear your watch, bluetooth headsets wireless pair with it for calls on the go.
The morning your phone stopped being the middleman

The buzzing that never stops
Your phone sits at the bottom of a bag and goes off every few minutes. You dig for it, unlock it, and find a message that could have waited. Your heart rate and last night's sleep sit somewhere in an app you never open, and the band on your wrist has a screen the size of a stamp.

A glance is all it takes
The 1.72-inch colour touchscreen is big enough to read without squinting. One glance shows the time, date, steps and kcal, and an incoming call lands on your wrist where you can answer it with the side crown. You stop reaching for your phone for things your wrist can already tell you.

Dressed for your day
Pick the matte black, pure white, blush pink or silver colourway that suits what you wear. The silicone strap is light and the case looks like a watch, not a gadget, so it works at the desk, on the train and at the gym without a change of wrist.

Questions and answers
No, and it does not claim to be. Heart rate and sleep come from the optical sensor on your wrist, and the blood pressure figure on screen is an estimate that shifts with fit and movement. Use it to spot trends across the week, and confirm any real concern with a clinical cuff or your doctor.
Yes. Pair it over Bluetooth with the companion app, then allow notification and call permissions on your phone. Once it is paired, calls, messages and music controls show up on your wrist. Pairing is the step people skip, so finish it before you wear the watch for the first time.
The strap is matte silicone with perforations, and the buckle is metal with a pin-and-tuck style fastening. Set it snug above the wrist bone for workouts so the sensor keeps good contact with your skin. If you like to switch looks often, silicone replacement watch bands fit a range of styles.
Flagship smartwatches often cost several hundred dollars, and most of that money goes to features a daily wearer never opens. This model covers heart rate, sleep, Bluetooth calls, music and sports modes on a 1.72-inch colour touchscreen. Spread the price over a year of daily wear and the cost per day stays low, which is the real value test.
Yes, especially for the fitness-minded friend or family member who wants data without a premium price tag. The pink and white colourways read as fashion pieces, and the big screen makes it easy to use without a lesson. Check that the recipient has a compatible phone before you buy.
