The everbeat Watch Key Components 
        Figure 2: Back of the everbeat watch 
1.  Battery Charger Leads – The two gold colored pickups on the far left of the bottom of the 
everbeat watch line up with corresponding pickups on the charging station. 
2.  PPG  sensor  -  The  green  light  is  a  photoplethysmogram,  or  PPG,  sensor.  It  has  been 
disabled and will not be used by the everbeat system at this time. 
3.  ECG Contacts – These ECG contacts on the bottom of the watch touch your wrist and 
create a circuit through your body when you touch the ECG sensor on the top of the watch 
face. Imagine a circuit starting from these two pickups, traveling up your arm, through 
your chest and down your other arm, and ending at your finger pressing on the ECG sensor 
on top of the watch. This is how everbeat records your ECG. 
4  Wrist Band – The wristband secures the watch to your wrist. It includes a button (#4), a 
loop (#5), and 10 adjustment holes (#6). 
7  Watch band screws – used to secure the band to the watch body. Not to be serviced by 
the user.
