I think you may be getting David Empson (of New Zealand) mixed up with me

[David Wilson (of Australia)].

I certainly posted information about the battery in a NSC.

If you remove the ROM chip from the NSC you will be able to see a chip,

PC board and a large letter (A/B/C/D/E/F depending on model of SmartWatch).

Placing the clock chip so that the letter is the right way up (and to the

right hand end of the chip, look for two small terminals to the right of

the letter (above and below). They should be marked - (the top one) and +

(the bottom one). You will see a trace leading from the -ve terminal to

the top righthand corner of the chip inside the SmartWatch. This goes to

both pins at the rh end of the chip then goes past the + terminal to the

external pin on the SmartWatch package (pin 12 or 14 depending on the model).

It looks like the +ve terminal is connected on the other side of the PC board.

If you were to cut the connection between the -ve terminal and the chip,

this would disconnect it. Then you could connect an external battery +ve
