Yep,replacement strap. We were devloping it to work with any device, but now with "accessory port" on Time, we will be able to leverage the battery and data connection to watch, which simplify the design. @Contactless: we are developing a new sensor technology for measuring HR which will not be in contact with the skin(like optical sensors/bio-impedance metal stubs). This means that the sensor is embedded inside the silicone strap as you can see in the demo video. Any suggestions ? pls mail me : ms@gethbeats.com
