Steps, heart rate and sleep show up on one round colour screen, and the watch swaps from silicone to mesh in a few seconds. It is built for fitness-minded adults who want real numbers without a premium price. Three straps come in the box, so one watch covers the gym, the office and the weekend.
Round color-display smartwatch with heart rate, activity and sleep tracking, available in interchangeable straps and finishes
- tracking daily activity and steps
- monitoring heart rate during workouts
- monitoring sleep
Every step, heartbeat and night of sleep on one round wrist
Stop guessing how you slept or how hard you pushed. Glance at your wrist and know, then swap straps and head out the door.
Steps, heartbeat and sleep in one glance

Your heartbeat, on your wrist
The built-in heart rate monitor tracks you through workouts and everyday wear without a chest strap. Outdoor running mode puts heart rate on screen mid-run, so you know whether an easy jog is actually easy.

Steps and sleep, at a glance
Steps, calories and sleep duration appear on the round colour display. You check your progress without unlocking your phone, and the sleep view tells you how long you actually stayed down.

Three straps, one watch
The silicone and mesh straps swap with the silver pin-and-tuck buckle. The pearl white finish uses imported Japanese paint, so the case keeps a soft pearl look rather than a flat plastic one.

Stop guessing how your body is doing

The guesswork
You finish a hard week and cannot say whether your body is recovering. Your phone logged a few thousand steps, but it had no idea what your heart was doing on the climb or how you slept after it. The workouts blur together and the mornings feel heavy for no clear reason.

Data on your wrist
The round colour screen shows steps, calories and heart rate in one glance. Sleep duration waits for you in the morning. Nothing needs unlocking, and the numbers sit exactly where you already look for the time.

One watch, every day
Silicone for the gym, mesh for the office, and the same watch for the walk home. Swapping takes a moment with the silver pin-and-tuck buckle, and the watch keeps tracking through the whole day into the night.
What you will notice over time
- First useSet your face and strap
Pick a watch face you like, swap to the strap for your day, and check that steps and heart rate show on the round display.
- Week 1Daily habits start to show
Checking steps and sleep each morning becomes routine. You begin to see how walks, workouts and bedtime line up across the week.
- 30 daysPatterns you can actually read
A month of logged activity and sleep gives a clear picture of your routine. Use the trends to decide when to push harder or rest more.
Easy care for silicone and mesh
- Rinse after sweaty sessions
Fresh water and a soft cloth take off salt, sweat and dust.
- Wipe the mesh
Mesh holds lint and sweat, so wipe it down after training.
- Let straps air dry
Dry the strap fully before the next wear to keep it fresh.

Questions and answers
Yes. The DK02 is listed for Android and iOS, so it pairs with either phone. Check the companion app setup on your phone before the first run.
The sensor sits on the wrist, which makes it a daily tracker for trends and session effort. A chest strap is still the better pick for precise training zones. For most fitness-minded adults, the wrist reading is enough to see how a workout landed and whether your resting pattern is shifting.
The DK02 carries an IP67 rating, which covers rain, sweat, splashes and washing up. Check the rating before taking it into a pool or open water, and rinse it with fresh water after salt or chlorine.
Yes. The silver pin-and-tuck buckle makes the swap quick. Snug the strap again after each change, since a different strap sits a little differently on the wrist during runs.
Your phone counts steps only while it is with you, and it has no sensor for heart rate or sleep. The DK02 logs steps, heart rate and sleep from your wrist, and it comes with two extra straps, so you get a full tracker for a fraction of what premium smartwatches cost.
The case uses a sturdy shell with pearl-like paint, the buckle is metal, and the mesh option adds a premium feel. Rinse the straps after sweaty sessions and the watch will keep looking fresh. The three-strap bundle gives real value for the price.
