The Prisma monitors your heart rate around the clock and turns it into clear daily trends in the Da Fit app — so a quick glance tells you how your day is really going.
The Prisma monitors blood pressure 24 hours a day — anytime, anywhere, with one-click measurement — and tracks blood oxygen saturation on demand, charting max to min so you can watch your health change instead of guessing. For wellness awareness, not medical diagnosis.
With a speaker and microphone built in, the Prisma handles calls from your wrist — perfect for cooking, driving prep or when your phone is buried in a bag.

Wear it to bed and the Prisma tracks your sleep scientifically — stages, duration and quality — then shows you a simple morning summary you can act on.
For wellness awareness and conversations with your physician — not a replacement for a medical device.
Intelligent AI algorithms combine with the watch’s own health data to predict menstruation, ovulation and safe periods — with thoughtful reminders in the Da Fit app so nothing arrives unannounced, and support for pregnancy planning too.
The built-in flashlight sounds like a gimmick until the first time you find a keyhole in the dark, check under the sofa or walk the dog at midnight. Then it becomes the feature you mention to friends.
From walks to full workouts, 100+ sports modes and scientific exercise tracking keep score of every session — steps, calories and heart rate included.
The 340mAh battery gives you 5-7 days of normal use and up to 30 days of standby — with magnetic charging when it finally asks for a top-up.

Screen technology is the one spec you interact with every single time you look at the watch. Here is what AMOLED actually changes.
That is the entire difference, and everything else follows from it. Black pixels on an AMOLED are genuinely off, which gives deep contrast and means a mostly-dark watch face costs very little power. An LCD backlight is on or off for the whole screen regardless of what is displayed.
Outdoors, the enemy is glare washing out the difference between text and background. High contrast is what wins that fight, which is why an AMOLED panel stays legible in conditions where an LCD of the same brightness does not.
On AMOLED, choosing a face with a black background rather than a bright photographic one measurably extends runtime, because unlit pixels draw almost nothing. That is not true on an LCD, where the backlight runs regardless. It is the easiest battery win available and most people never try it.
Even on an efficient panel, keeping the display lit permanently is the largest single drain on any smartwatch. Turning it off and letting the screen wake on a wrist raise is usually the difference between a week and a month. See what actually drains a watch.
Heart rate is the reliable figure; blood-pressure and SpO2 estimates are optical and shift with fit, motion and circulation, so read them as trends against your own baseline. The American Heart Association target heart rate guide has the ranges and the CDC activity guidelines the weekly targets. The flashlight is genuinely useful — see everyday flashlight watches.

For a watch, generally yes. AMOLED lights each pixel individually, so blacks are truly off and contrast is far higher, which is what keeps the screen readable in direct sunlight. It also means a dark watch face uses noticeably less power. The trade-offs are cost and that very bright, mostly-white content draws more than an LCD would — which is why watch faces on AMOLED tend to be dark by design.
Not by itself — how you use it decides. Prisma quotes up to 30 days of standby with the display waking on a wrist raise. Switch on always-on display and that figure falls sharply, regardless of screen size. If you want the big screen and the battery, keep always-on off and pick a dark watch face; on an AMOLED panel both genuinely help.
Pair it with your phone over Bluetooth and incoming calls ring on your wrist. Answer through the built-in speaker and microphone — no need to touch your phone.
With normal use expect 5-7 days per charge; in standby the 340mAh battery stretches up to 30 days. Charging is magnetic and takes about two hours.
