Inside the watch there is a water proofing o-ring normally held in a guide groove by the back cover plate. Also exposed is a flange held in place by 4 mounting screws. The flange is in electrical contact with landing pads on either side of the watches top most circuit board. Be careful there is a very small spring that makes contact with a pieazzo electric element on the back case of the watch which is now free to fall out. | |||

Pictured inside the case to the right of the images you can see the PCB landing for the watches "joystick", which is bolted to the case. On the far side, or top, of the case pictures are three small metal points which allow for the watch's serial signals to pierce the case. There are also 4 non-metal points piercing the watch case in order to allow for button function. | |||
