Heart Rate Smartwatch with IP67 Waterproof Sport Tracking

Heart rate, steps and rings on one round screen

Live heart rate, no chest strap

The built-in sensor shows a live BPM on the dial, like the 068 BPM reading shown on screen, with a heart-rate graph beside it. Glance down between sets and you know whether you are pushing or coasting. No band around your chest, no extra gear in the gym bag.

Built for sweat and rain

The IP67 rating covers splashes, rain and handwashing, so you keep the watch on at the sink and through a downpour on the walk home. It is rated for water resistance, not swimming or diving, so take it off before a pool or the sea. Pair it with a watch bands set if you want a backup strap for wet days.

Looks like a real watch

The full round touchscreen runs edge to edge under a glass face, finished with a polished metal buckle and a matte silicone strap. Swap between jet black, blush pink, steel silver and deep teal blue. If you want a different texture, a silicone wristband fits the same idea.

Guesswork ends on your wrist

The guessing game

You start a workout with no real sense of effort, and the walk you planned for a step goal ends up as a guess. A chest strap would fix the number, but it is one more thing to clip on every morning.

The rain and the handwash

The tracker comes off when the sky opens up or your hands hit the sink, then it sits in a pocket until the next day. Half the week goes uncounted, and the numbers you did get are missing the best parts.

A watch that stays on

The ZL02 keeps live BPM, your step count and activity rings on a round screen. It stays on through sweat, rain and washing up, so the numbers keep coming in all week.

What to expect as you start

1. First use
   Pair, set up and check your BPM

   Set your time and basics, then check the live heart rate on the dial during a short walk. Compare the readout to your own sense of effort to get a feel for it.

2. Week 1
   Build the habit of wearing it

   Wear it through daily life and a few workouts. Checking your step count and activity rings becomes a quick habit, and you start to notice your normal pace.

3. Week 4
   Spot trends in your activity

   Your activity rings and heart-rate graph start to show patterns, so you can see which days you move more and which days you slip.

4. Day 90
   Use it as a routine check-in

   Tracking becomes part of the routine. Treat the data as a rough guide to your effort, not a medical measure, and adjust your training from there.

Rinse, dry and wear it again

• Rinse after sweaty sessions

  Clean off sweat and grime from under the silicone with water.

• Dry before you wear it again

  Let the watch air out so trapped moisture does not sit against your skin.

• Wear it snug, not cinched

  About a finger's width above the wrist bone keeps the sensor in steady contact.

• Swap straps to rotate wear

  Alternating colors gives each strap time to dry out between workouts.
