The Syntra pairs a bold 1.73-inch always-on AMOLED with round-the-clock heart, blood pressure, oxygen and sleep tracking — plus Bluetooth calls from your wrist and a battery that runs 7–10 days between charges.
✓ Free shipping ✓ 30-day money-back guarantee ✓ Works with iPhone & Android
Six tools that quietly work all day, behind a watch face you’ll actually want to wear.
Round-the-clock tracking that nudges you when your numbers wander off course.
A few seconds against your wrist and your oxygen saturation is on screen.
Guided breathing sessions to slow a racing day back down.
Answer and make calls straight from the watch — phone stays in your pocket.
Your night mapped automatically — depth, duration and disturbances.
A two-hour magnetic charge runs the better part of two weeks.
Energy dips, restless nights and a heart that races on the stairs all leave traces. The Syntra logs them quietly in the background, so you argue with data instead of guessing — and change habits before they change you.
No cuff, no pharmacy queue, no waiting room. Glance at your wrist with your morning coffee and your reading is logged — building a history your doctor can actually work with.
For wellness tracking and awareness — not a replacement for a medical blood pressure monitor.
Check your blood oxygen whenever you like, then let the guided breathing sessions walk you back to calm — slow inhales, slow exhales, measurable results on a screen big enough to follow.
Designed for awareness and conversation with your physician — not for diagnosis.
Wear it to bed and wake up to the whole story — how long you slept, how deep it went, and how tonight stacked up against the rest of the week. Fixing sleep starts with seeing it.
Walking the dog, carrying shopping, elbow-deep in the garden — when the phone rings, just talk to your watch. Built-in speaker and mic keep the conversation going while your hands stay busy.
For the parent who never mentions the dizzy spells or the partner who skips check-ups: a watch they’ll wear for the style, that quietly keeps their heart, pressure and sleep on record.

“Charged it when it arrived, charged it again over a week later. My blood pressure log goes with me to every appointment now.”
“I bought it because it looks nothing like a medical gadget. The heart readings while I’m gardening are the part I’d never give up.”
“Took a call on my wrist with a coffee in one hand and the lead in the other. Sound is clearer than I expected.”
