T-BAND HD (Hidden Display) model is designed for people who want all of the smart watch functions while being super discreet. LED panels are embedded below a thin “membrane” like material which hides the display. When it’s turned off (default mode), the T-band HD actually looks like the ND model (rubber band). When there is a push notification or alert, the hidden LED panel lights up and display the necessary information. Battery life is same as the OD model (200mAH) which is expected to last 2-3 days on a full charge. The HD model however has one downside- it can only display English alphanumeric text and numbers. Non-alphabet characters (such as Chinese, Japanese, Korean Arabic, Russia, etc.) will not be displayed. Images and videos are also not able to be displayed through this model.
