Morepro V19 health watch (used but working)

​ECG/EKG Monitoring: This is the V19's "party trick." You touch the metal electrode on the front, and it gives you an electrocardiogram reading. It’s designed to spot things like arrhythmias or atrial fibrillation. (Just don't fire your doctor yet; it's a $40 watch, not a hospital rig).
​Dual Light Detection: It uses both green and infrared light. Green for heart rate and infrared for Blood Oxygen (SpO2) and Blood Pressure.
​Scientific Sleep: Unlike basic trackers, this monitors your respiratory rate and "OSAS" (obstructive sleep apnea symptoms) during the night.
​Direct USB Charging: No annoying proprietary cables to lose. You just pull the strap off and stick the watch's "tongue" directly into a USB port like a tech-themed popsicle.
​The Technical "Meh" Factors

​Waterproof: It’s IP68, so it’s fine for a shower or a rainy run, but don't take
