A bracelet first
It looks like jewelry because it is jewelry
A fine metal chain bracelet, built like a watch bracelet, with a pulse sensor hidden inside the center plate. No screen. No buttons. Nothing that lights up across a dinner table.
Most fitness trackers ask you to wear rubber and glass with everything you own. This one asks nothing. It sits on your wrist looking like the bracelet you already reach for, quietly counting in the background, and you look at the numbers later on your phone — if you feel like it.
The part people are surprised by
There is genuinely no screen
The center plate is solid metal with a glitter inlay panel set into it. It is not a dark display waiting to wake up — there is nothing behind it to light up, and there are no buttons anywhere on the bracelet.
That is the entire design idea, and it is worth being clear about before you buy. You cannot check the time on it. You cannot read a message on it. Nothing will glow on your wrist in a meeting, a cinema or a restaurant, because there is nothing there that can.
Everything the bracelet records is read in a phone app, over a Bluetooth Low Energy connection, when you choose to open it.
What it measures
Everyday numbers, not medical ones
Inside the plate there is a motion sensor and an optical pulse sensor — the small dark window that sits against your skin. Between them they give you the ordinary things: how much you moved, and an estimate of your pulse.
We want to be plain about the limits of that, because this category is not plain about it. These are fitness estimates from a consumer optical sensor on a moving wrist. They are the kind of number a step count is: useful for noticing a trend over a week, not for deciding anything.
- It is not a medical device. Nothing it shows is a diagnosis, and nothing it shows should be used to make a decision about medication or treatment.
- It does not detect or warn about any condition. It cannot tell you about your heart rhythm, your breathing at night, or your blood pressure, and it is not designed to try.
- If something about your health worries you, see a doctor. A bracelet is not a reason to wait, and a reassuring reading is not a reason to wait either.
Where it fits
The gap between a fitness band and a bracelet
Read that middle column honestly. A fitness band does more. If you want your numbers on your wrist, at a glance, without reaching for a phone, buy the band — you will be happier. This is for the person who has tried that and quietly stopped wearing it because it looked wrong with everything.
Materials and fit
Zinc alloy, in two finishes
The chain and plate are zinc alloy with a polished plated finish, and the sparkle down the center of the plate is an in-mold inlay panel rather than set stones. It is built as a pinned-link watch bracelet, the same construction as a metal watch strap.
- Two finishes. A warm rose-gold tone and a bright silver tone. Both have the matching glitter inlay.
- The center plate measures about 1.45 in long and 0.37 in wide (36.8 × 9.4 mm). That is the plate only — the chain runs from both ends of it around your wrist.
- Sizing. Because it is a pinned-link bracelet, a jeweler can usually take links out to shorten it. We have not confirmed whether a sizing tool or spare links come in the box, so treat that as something to ask us before you order if your wrist is very small or very large.
- A note on zinc alloy. Plated zinc alloy costume jewelry can contain nickel, and our supplier does not document the nickel content of this piece. It is worn against the skin all day, so if you react to costume jewelry, this is not the one to gamble on.
Living with it
Three things worth knowing
It has to be charged
There is a battery in the plate, so it is a thing you charge, not a thing you forget. We have not bench-tested how long a charge lasts on this unit, so we are not going to print a figure we cannot stand behind.
Keep it dry
Our supplier has not documented a water-resistance rating we are willing to repeat, so treat it as jewelry with electronics in it. Take it off to shower, swim or wash up.
The app is where it lives
Without a phone paired to it, the bracelet is a bracelet. Everything it counts is read on the phone, so it suits someone who actually wants to check in occasionally rather than constantly.
Being straight with you
Who should not buy this
It is a narrow product and it is better for you to know now than to find out in a week.
- Anyone tracking a health condition. This is a fashion accessory that counts movement. If you need reliable physiological data, you need a medical device and a clinician, not this.
- Anyone who wants notifications on their wrist. There is no screen and nothing to read. That is deliberate, and it is not going to suit you.
- Anyone who swims or showers in their tracker. Take it off. If you want something you never remove, this is the wrong shape of product.
- Anyone with a nickel sensitivity. Until the alloy is documented, it is not worth the reaction.
- Anyone who wants to know the time. Genuinely — it is a bracelet.
Questions people ask
Does it really have no screen at all?
None. The center plate is solid metal with a glitter inlay set into it. The only thing under the surface is the sensor window on the underside, which sits against your skin. Nothing on the bracelet displays anything.
Can it measure my blood oxygen?
We are not claiming that it can. The sensor our supplier documents is an optical pulse sensor of the type that uses a green light source, and that kind of sensor reads a pulse — measuring blood oxygen needs red and infrared light sources as well. Until we can verify the hardware ourselves, we would rather tell you plainly that we cannot stand behind a blood-oxygen reading from this bracelet.
Can it measure blood pressure?
No, and please do not buy any wrist device on that basis. A consumer optical sensor cannot measure blood pressure without being calibrated against a cuff, and we make no blood-pressure claim for this product at all.
Will it tell me if something is wrong with my heart?
No. It does not detect, monitor or warn about any medical condition, including irregular heart rhythms. If you have a concern about your heart, please speak to a doctor rather than a bracelet.
How accurate is the pulse reading?
Treat it as an estimate. Optical sensors on a moving wrist are affected by fit, skin tone, temperature and movement, and a loose metal bracelet is a harder case than a snug elastic strap. It is useful for a general sense of trend, not for a precise number.
Can I wear it in the shower or the pool?
Please do not. We are not repeating a water rating we cannot verify, so the safe assumption is that it is not waterproof. Take it off before water.
Does it track my sleep?
It records movement and pulse overnight and the app presents that as a sleep estimate. It is an inference from how still you are and how your pulse behaves, not a sleep study, and it cannot detect anything clinical about your sleep.
Will it fit my wrist?
It is a pinned-link bracelet, so links can usually be removed to size it down. We have not confirmed the supplied length or whether a sizing tool is included — if your wrist is at either extreme, message us before ordering and we will find out for you.
Does it work with an iPhone and with Android?
It pairs to a phone over Bluetooth Low Energy, which both platforms support. We are confirming the exact companion app and its minimum operating system versions with our supplier, and we will publish those here once we have them in writing.
The tracker you will actually keep on.
Not because it does the most. Because it looks like something you would have worn anyway.
