The high-performance heart rate sport watch

...for runners and cyclists

Before ALPHA, HR monitor choices fell short in terms of comfort and ease of use. Alpha's disruptive technology changes the game - and training for it too.

Accurate at high speeds

Built for performance

Alpha uses patented technology from the research labs at Philips Electronics, to achieve precise heart rate readings.

Comfort, Form, Function

Take it anywhere, no set-up, always be ready for action

Totally unobtrusive, ALPHA delivers maximum performance in ultimate comfort. No chest strap means no worry it will slide down or chafe. Alpha's soft, stretchable silicone wrist band ensures a snug fit in a form factor that won't slow you down. So comfortable, you can wear it all day!

Data review (total exercise time; average heart rate; time "in zone") Bluetooth Smart connectivity

Technologically Advanced

Two light beams and an electro-optical cell "sense" the volume of blood under your skin

Alpha is a true scientific breakthrough. Technology proven accurate at rest in medical use is now robust enough for sport. Sophisticated algorithms are applied to the pulse signal so that the heart's true rhythm can be detected even while running at performance speeds

Added data such as speed, GPS, distance & pace

Alpha uses Bluetooth ® Smart (4.0) technology to connect to compatible devices
