Every claim below comes straight from the manufacturer panels — measured, not embellished.
A 368×448 high-resolution curved display with 2.5D glass and an ultra-wide viewing angle — fluid, bright and pleasing to touch.
Just 6.9mm thin and feather-light — a health watch that disappears on the watch whenever you want a closer look at your heart rhythm.
Continuous heart-rate monitoring plus on-demand SpO₂ readings, running 24/7 in the background.
Advanced algorithms break your night into deep, light and REM phases so you can actually improve your sleep habits.
Answer and make calls from the watch itself — speaker and microphone are built into the slim metal case.
Just 7.5mm thin and 45 grams with a rotating crown — a watch you forget you are wearing.

Most smartwatches announce themselves. At 7.5mm thin and 45 grams in a rounded metal case, the Equilibrium slips under cuffs and past bedtime without a second thought.
Pick from multiple movement modes — running, cycling, rope skipping and more — and the Equilibrium tracks each session with live heart rate, then files it neatly in the app. Training structure, without the bulk on your wrist.


Continuous heart-rate monitoring runs around the clock, and blood-oxygen readings are one tap away — 24/7 health monitoring in a watch that looks nothing like a gadget.
For wellness awareness and conversations with your physician — not a replacement for a medical device.

The slimmest watch in our range still carries a blood-pressure monitor: take a cuff-free reading whenever you like and watch your trends build day by day in the app. Wellness insight, not a medical device — but a habit that weighs nothing.
Advanced algorithms stage your night into deep, light and REM sleep, so mornings come with understanding instead of guesswork — and your habits actually improve.


A speaker and microphone hide inside the slim metal case, so calls happen from your wrist while the groceries, the leash or the coffee stay right where they are.

The curved 1.96-inch AMOLED at 368×448 meets 2.5D glass for an interface that feels fluid under your finger — with an ultra-wide viewing angle from any tilt.

“The sleep breakdown finally explained my 3pm crashes. Light sleep all night. Fixed my caffeine, fixed my nights.”
“So thin it fits under my dress shirt cuff. Takes calls while I cook. My old watch felt like a brick after this.”
