A smart watch doesn’t require very much current. A ribbon cable should be more than sufficient for a device that can last days on a 185mAh battery. Especially since a ribbon cable is already delivering most of the power to the device’s main board.
But I agree that a soldered on battery isn’t a big deal.
How much current does that thin ribbon cable carry? Battery connectors need to be more robust.

Should still be able to carry 1 amp, shouldn’t it?
