I recently picked up the Samsung Gear Sport for the possibility of skydiving with it, tracking my daily activity, and getting notifications from my iPhone. Temptation got the best of me, and around hour one, I decided to have a look what's inside.

Disassembly of SM-R600 (Samsung Gear Sport)

Overall, disassembly is easy. Just remove the four, 3-wing screws located in each corner. The bottom pops off with a gentle pry from a spudger. Obviously, be sure to clean off both mating surfaces before closing the unit back up for waterproofness.

Once inside, carefully remove the only screw. Be careful not to touch the pad next to the diode as that is the battery output.

Placing a piece of Mylar or similar insulator here will disconnect the battery. I would highly recommend doing that before continuing.

Removing the connector and sliding it through the carrier will disconnect the board/battery carrier from the watch face. In this shot, I removed the EMI copper tape to get a better look at the processor stack.

Note: The NFC antenna is the coil on the bottom left.

A cover keeps the battery in place and some adhesive keeps the battery from sliding aft.

Just bellow the battery are three hall effect sensors for sensing the spinning bezel.

The flex push button assemblies are simply taped on to the carrier.

Here is the backside of the motherboard with two more enclosed EMI shields and the antenna front end (top right).

The backside of the carrier houses the two pins for the RF antenna to connect to the body and the haptic feedback source.

It's interesting that they use the stainless steel body as the RF antenna. The two antenna pads can be seen above. Note the housing's metal is sealed so these two access points are the only conductive surface on the body. Unfortunately, I don't have a LRC meter to find out the "antenna's" impedance, but this is an extremely interesting technique.

On the case's backside we can see the o-ring sealed pressure sensor, wireless charging-charging coil, and window for the HR sensor. There are also three magnets that give the rotating bezel its 'click'. I'm unsure why there is an additional MEMS pressure sensor on the main board with this submersible sensor, but it's there. Perhaps someone that knows can drop us a line.

Wow, the display assembly packs a lot in a small space. 360x360 16M colors AMOLED display, ambient light sensor, and gesture touch sensor, all protected by Corning® Gorilla® Glass SR+.
