The collaboration between Quanta and Foxconn drew a lot of attentions from investors with the view that if Quanta was limited by the defect-free rate, its output would be lower, which could result in Quanta loses to other OEM/ODM firms. It was understood that Foxconn is more likely to be another Apple Watch assembly firm than Inventec.

However, Apple Watch debuted on March 9 at its press conference but until April 10 for pre-orders, the one month waiting time is maybe because of Quanta's defect-free rate is below expectations.

Allegedly, due to the negotiation between Apple, Quanta teamed up with Foxconn in borrowing 3,000 workers for manufacturing Apple Watch. It's widely circulated that currently the defect-free rate of Quanta is below 30 percent.
