Starting with a generic activity tracker saves a huge amount of time and cost. This is what they look like on the inside. Usually 90%+ of mass market electronic device manufacturing costs are upfront factory equipment and facilities. Raw material and labor cost are usually extremely low. Because of this a $20 activity tracker will often have the exact same components and build quality as a $300 device.
Carving up activity tracker enclosure so it will fit into 3D printed locket interface. Holes for wires etc.
I modeled an adapter to connect the back half of the activity tracker enclosure to the modified locket. You can 3D print this adapter yourself using files attached to this project.
