Monitor and calculate your heart rate and blood pressure with this Smart Watch & Heart Rate Monitor. Heart attacks are the leading cause of death according to healthday.com so having a device that is able to inform you on your heart condition is very important. 
This powerful Smart Watch & Heart Rate Monitor does not only inform you about your heart rate, but also detects various health problems as well!
How do Smart Wrist Watches measure the heart beat on the wrist?
The heart rate monitor is based on a difficult to pronounce technology called photoplethysmography, but it basically comes down to using green LED lights paired with light‑sensitive photodiodes to illuminate your skin and measures changes in light absorption.
The sensor is designed to compensate for low signal levels by increasing both LED brightness and sampling rate. That’s why the heart rate sensor on the back of the device flashes its LED lights hundreds of times per second, helping the device calculate heart rates precisely.
But when it measures your heart rate every ten minutes, the Watch switches to using infrared light. And if it fails to provide an adequate reading while using the infrared light, the device switches back to the green LEDs.
In order for the sensor to work as advertised, the Watch must be close to your skin. The company advises tightening the band in case the sensors aren’t reading your heart rate accurately.
All in all, the heart rate sensor in the Watch is a great feature, especially if you’re something of a fitness buff. It checks your heart rate during workouts for an at-a-glance overview of both the intensity level and the heart rate change over time.
