Rugged square smartwatch with all-day health monitoring and long standby
- need to track heart rate and health daily
- wanting a durable watch for outdoor use
- phone-free calls and notifications on the wrist
Track Your Health on the Trail, Without Your Phone
Stop digging through your pack for your phone to check your pulse. The K57PRO keeps heart rate, steps and calls on your wrist, built for the way you actually spend your days.
Square Screen, Rugged Frame, Easy Controls

A Square Screen You Can Read
The 1.96-inch square IPS touchscreen puts heart rate, steps and weather in plain view. The square face gives you more room than a round dial of the same width, so the numbers you check most sit where your eye lands. Brightness holds up in daylight on a trail or a bench outside.

Rugged Metal-Look Frame
The bezel carries corner screws and a metal-look finish in gunmetal black or brushed silver. The strap is textured silicone with vent holes, closed by a metal buckle clasp. It looks like a tool watch and wears like one, without the premium price that usually comes with that look.

Crown and Buttons for Gloved Use
The rotary crown has an orange accent you can find by feel. POWER and BACK sit on the side, so you move through menus without fumbling for a touch target. Calls, contacts and the voice assistant are all reachable from the same few controls.
Ready on Your Wrist in Three Steps
- 1Charge the watch
Charge it fully before the first wear so the battery is ready for a full day of tracking.
- 2Pair it with your phone
Install the companion app, pair over Bluetooth and set your profile. Notifications and calls start to appear on the wrist after pairing completes.
- 3Wear it snug
Set the strap so the back sits flat on your skin without digging in. A snug fit keeps the sensor in contact during movement, which helps the heart rate and oxygen readings stay steady.
Your Phone Should Not Be Your Health Monitor
The Phone Stays in the Pack
Halfway up a climb, the question is always the same: how hard am I working? The phone is buried under a rain shell and a water bottle. You stop, dig, unlock, and by the time the screen loads your breathing has already told you the answer. Fitness data that lives in a pocket is data you check too late to use.
A Watch That Keeps Up
The K57PRO puts a 1.96-inch square IPS screen on a metal-look bezel with corner screws. The face is bright enough to read in daylight, and the strap is textured silicone with vent holes that stays put once it is snug. It is the kind of watch you forget about until you need it, which is exactly the point.
Your Day, on Your Wrist
Heart rate and steps sit on the face from the first trailhead to the last train. Calls and contacts run from the wrist, and the voice assistant handles quick tasks without a phone in hand. A rotary crown with an orange accent and the POWER and BACK buttons keep the controls simple, even when your hands are cold or gloved.

Questions and answers
No. The K57PRO is a consumer smartwatch. Heart rate, blood pressure and blood oxygen numbers are for spotting trends across your week, not for diagnosis. If a reading worries you, see a doctor.
The metal-look bezel and silicone strap are made for trail, gym and bad weather, so sweat and rain are normal use. Swimming or diving needs a confirmed water rating, so check the product spec before you go in the water.
Long standby is the headline feature, and it is what makes a multi-day trip workable. The listing does not publish a verified runtime in hours, so charge it fully before you leave and top it up whenever you get the chance.
Yes. Calls, contacts and the voice assistant run from the wrist, and notifications show on the screen once you pair the watch through the companion app.
The textured silicone strap adjusts and closes with a metal buckle clasp. Aim for snug, with the back flat on the skin, which also keeps the sensor steady during workouts.
Premium outdoor watches cost several times more. If you want a rugged metal-look frame, a bright square screen, heart rate, blood oxygen and calls on the wrist, the K57PRO covers that daily use at a fraction of the cost.
