A tracker that's off records nothing
Smartwatches light up in meetings and buzz at 6 a.m. Fitness bands read as gym gear with everything else you own, and a fixed-size ring can't follow a wrist that changes through the day. So the tracker comes off the wrist and the data stops.
- No display and no vibration alerts, so there's nothing on your wrist to react to
- A pavé bar on a woven chain that reads as a bracelet, not as gym gear
- A sliding bolo clasp that follows a wrist that swells or shrinks
What it tracks, and what it keeps quiet
Five things the bracelet does, and one it doesn't.
Screenless by design
No illuminated display and no vibration alerts. You read heart rate, sleep and stress in the app, when you decide to, instead of reacting to your wrist.
Full-body tracking
Heart rate, heart rate variability, blood oxygen, stress levels, sleep duration and quality, and daily activity, all in one app. No subscription required.
Sliding bolo clasp
Two chain tails run through a slider bead, so one bracelet adjusts through the day and works over or under a sleeve.
10 ATM water resistant
Rated for the shower, the pool and swimming, so the hours you'd normally take a tracker off still get recorded.
5 days, 2-hour charge
Up to five days and nights per charge, then a full magnetic charge in about 2 hours. One top-up covers a week of sleep.
What it doesn't do
It's not a medical device. It doesn't diagnose or monitor any condition, doesn't measure blood pressure, and replaces nothing your doctor does. There's also no time, no notifications, no step count and no alarm on the bracelet itself, and no vibration to wake you.
Fits a day that doesn't stop
The same bracelet, from the first meeting to lights out.
Who this bracelet is for
Great for
- You want sleep and heart data without a screen on your wrist
- Your work or your outfits rule out a smartwatch
- You shower and swim without taking your tracker off
- You sleep in your tracker and don't want wrist vibration
Not the right pick if
- You want time, steps or notifications visible on your wrist
- You need a vibrating alarm or move reminders
- You want blood pressure or any medical-grade reading
A pavé bar that carries the sensors
The whole tracker lives in one curved bar module, with jewelry on both sides of it.
- Bar about 1.6 in long and 0.22 in (5.6 mm) thick, curved to follow the wrist, with roughly five rows of pavé stones
- A short run of prong-set crystals at each end feeds into a woven mesh chain about 2 mm across
- Both chain ends pass through a smooth slider bead and hang as two ball-tipped tails; 0.4 oz (12 g) total

Getting the first five days right
Three things to do before you wear it to bed.
Charge it first
Give it a full 2-hour magnetic charge before day one, so your first night of sleep data runs end to end.
Set the slide once
Slide the clasp until the bar sits flat on top of your wrist, snug but not tight, then check it again after an hour.
Pick a top-up slot
Dry it fully, then charge during a shower or a workout. Two hours from empty covers about five days and nights.
One bracelet, one charger
- Activity tracker bracelet in the finish you choose - one bracelet, not a three-piece set
- Magnetic charging cable

What people ask most
Will it fit my wrist?
It's one size, adjusted by the sliding bolo clasp, so it covers a range rather than a fixed measurement. The supplier doesn't publish exact minimum and maximum wrist sizes, so a very large or very small wrist may fall outside the clasp's range.
How long does the battery last and how do I charge it?
Up to 5 days per charge. A full charge on the magnetic charger takes about 2 hours. Dry the bracelet completely before placing it on the charger.
Is it a medical device?
No. It records heart rate, heart rate variability, blood oxygen, stress, sleep and activity as wellness data only. It doesn't diagnose or monitor any condition and doesn't measure blood pressure. For anything health-related, talk to a doctor.
Can I shower and swim in it?
Yes. It's rated 10 ATM, about 330 ft (100 m), for the shower, the pool and swimming. It isn't rated for diving, hot tubs, steam rooms or high-pressure water jets. Rinse with fresh water after the pool or ocean.
How do I clean it?
Rinse with clean fresh water after salt or chlorine, dry it fully, then wipe the chain and pavé bar with a soft dry cloth. Keep lotion, perfume and hairspray off the stones.
What comes in the box?
One bracelet in the finish you choose, plus the magnetic charging cable. The three bracelets shown together are the finish options, not a set: one order is one bracelet.
