There are several problems:
	1.	The temperature in a computer tends to fluctuate much more
		than the temp of a watch.
	2.	The electrical noise environment in a computer is rather
		severe.
	3.	The power supply voltage to the chip _may_ be different
		depending on whether the computer is on or off.
