Know your heart, steps and sleep at a glance
Stop digging through your phone mid-workout. Read your heart rate, steps and calories on a large wrist screen and move on with your day.
A bigger screen you can read at a glance

Read your heart rate mid-set
The heart rate monitor shows live readings on the full-color touchscreen, so you check effort without stopping the set. Pair it with a heart rate fitness tracker routine and you get a steady read on every session.

Answer calls on your wrist
The watch answers calls and controls music from your wrist. On a ride or a run the phone stays in your pocket, and a missed call no longer means a stopped workout.

Sit less, move more
Sedentary reminders and the step counter turn a long desk day into visible movement goals. The watch nudges you up from the chair, and the step count tells you whether the walk to the kitchen counted.
Inside the box
- 1Open the box
The smartwatch rests on a soft insert, its brushed-metal bezel catching light as you lift it out.
- 2Meet the screen
Power it on and the full-color touchscreen lights up with the time, steps and heart rate. Use the side crown to move between screens.
- 3Fit the strap
The black silicone strap clicks into the quick-release pins with a firm snap, and the brushed buckle closes with a solid tug.
Stop checking the phone mid-set
The phone that always gets in the way
You are halfway through a set and the phone buzzes in your pocket. You reach for it, check who called, check your pace, and the count is gone. Multiply that by every workout and every ride and the phone becomes the thing that keeps you from training.
Your numbers, right on your wrist
The large full-color touchscreen puts heart rate, steps, calories and distance in one glance. Switch between readings with the side crown and the watch becomes the place you check instead of the phone.
A watch that fits your whole day
Gym sessions get a live heart rate and stopwatch. Desk days get sedentary reminders and a step count you can see. At night the sleep log runs in the background and the alarm wakes you on your wrist.
What to expect over time
- First useWatch set up and paired
Set your time, wear the watch and check the readings on the touchscreen. Most of the first session is learning the side crown and screen gestures.
- Week 1Daily habit forming
You start checking steps and sedentary reminders each day. Glancing at your wrist replaces reaching for your phone.
- Day 30Patterns start to show
Logged steps, sleep and workout heart rate give you a clearer picture of your routine over the month.
Easy care for sweaty workouts
- Rinse after sweaty sessions
Run the silicone strap under water and dry it before you wear it again. Sweat left on the band is what attracts lint.
- Wipe the screen and bezel
A soft dry cloth clears sweat and dust from the touchscreen and the metal bezel.
- Keep the mesh dry
If you wear the milanese mesh band to the gym, shake off moisture and let it air dry.

Questions and answers
No. The packaging confirms heart rate, sleep, sedentary reminders, multimotion mode, cycling, call answering, music and camera control. Treat any blood pressure or temperature reading as a wellness estimate for spotting trends, not a diagnosis. Talk to a clinician before you make a health decision based on the watch.
The heart rate monitor gives live readings on the touchscreen during workouts, which is what most people need to pace a session. Wear it snug above the wrist bone so the sensor stays against your skin. Use the numbers to follow trends across weeks rather than to set precise training zones.
Fit it snug above the wrist bone, not loose enough to slide. The strap is adjustable through the metal buckle. If you are between sizes on a silicone band, go snug for workouts, since a loose fit lets the sensor move.
Yes. The strap uses quick-release pins, so you press the release and slide the band out. Snap the black silicone or the milanese mesh option back in with a firm click. No screwdriver or pin tool is needed.
Yes. The watch answers calls and controls music from your wrist, so your phone can stay in a pocket or bag during a ride, a run or a set at the gym.
You get a full-color touchscreen, a metal bezel with a side crown and a second strap style, in one box with the watch and a black silicone strap. A basic band has a smaller screen you squint at mid-set. A flagship smartwatch costs several times more for features you may not use every day. This one covers the daily tracking at a price that makes sense.
