The Fitbit Surge was released in 2015 and is identifiable by model number FB501BKL. This is a smartwatch that is capable of monitoring your heart rate, pace, elevation, and distance.

gyroscope and a accelerometer

Did not see these items in your teardown of the FitBit Surge. Are they in there and could you tell me who the MFG is?

Looks like a MEMS 3-axis accelerometer, but I can't find the part number for that or the gyroscope without the device in hand. Maybe https://www.ifixit.com/User/1210134/Tiag..., the author of the teardown, still has the device and would be willing to look?
