Reliable beacon/ibeacon wearable

Anyone has suggestions for a beacon/ibeacon that is reliable (constantly sending out signal and not once every or based on movement) and that can be worn as a bracelet (or alternative…?) while looking good?
Not some nerdy solution that is only functional, it also has to be somewhat fashionable :slight_smile:

You can try a Fitbit device or iWatch

solved it with a card beacon behind the cover of my smartphone
