Japanese electronics company Epson will launch its health sensing smartwatch, called Pulsense Watch, and fitness band, called Pulsense Band in September. Consumers can preorder the device on Epson's website until then. The company first announced the devices at CES in January.

The Pulsense Watch costs $199, while the Pulsense Band costs $129.

"The Pulsense product line will be Epson’s first smart wrist wearable devices to leverage the company’s patented Bio sensing technology," Epson America New Ventures Director Anna Jen said when she announced the product at CES. "These products showcase Seiko Epson’s heritage in wrist watch technology and consumer electronics manufacturing. Pulsense has set the performance and features benchmark for the next generation of activity monitors." 

Both devices offer heart rate monitoring, step counting, calories tracking, and sleep sensing features. Epson says the device can continuously sense heart rate and works as a replacement for a chest strap. The company explains that the sensor measures "the amount of light reflected from red blood cells" to measure heartbeats.

The companion app, which is compatible with iOS and Android devices, maps a user's health progress. If a user enters in health goals, like goal weight, then the app will also set targets levels for the user to reach based on past biometric data. The devices have built-in memory that can store up to 480 hours of heart rate data before needing to transfer the information to the companion app.

The company also launched a developers program for app makers to create apps that integrate with the fitness devices. So far fitness app makers Digifit and Custom Fit4You have integrated their apps with the devices.
