When I worked for Texas Instruments way back when they sold watches, that is 
what they did to keep static electric discharges from frying the insides
of the watches.  They were using plastic cases and found that static would 
travel through the unshielded case and ruin the microprocessor.

So they huddled together and decided to acquire a large chamber that bombarded 
the inside of the plastic cases with metal ions to produce a barrier
through which the static electricity could not travel.  It worked quite well.

In fact the results were so nice that they decided to start using it on the 
outside of the case to produce a metal look in either silver or gold.

Cheers,
Joe
