@Briggsy1182: Please try pressing the Home and Back buttons simultaneously for around 10 seconds to see if you're able to force a restart. If you are using the original charger that came packaged with the watch, and if the device remains unresponsive after placing it on charge, then please head to samsung.com > Scroll to the bottom of the page > Contact us, and get in touch via your preferred channel, and an advisor will be able to arrange for an authorised engineer to inspect the device.
