According to the document, the company attempted to use lead-free solder in the manufacture of the quartz crystal oscillators that keep time in its watches. The company said as much as 30% of the lead-free oscillators had metal whiskers growing from them, and 5% had short-circuited because of the whiskers.

The company's figures are in line with an estimate by metal whisker expert and Uptime Institute Senior Consultant Robert Sullivan, who says 20% to 30% of electroplated sheet metal will grow whiskers.
