Advisory firm says no Apple Watch units were shipped with a faulty taptic engine14
Because AAC Technologies' version of the taptic engine failed its longevity tests, there was some fear at Apple that some consumers would find their Apple Watch not working all of a sudden. The taptic engine is supposed to alert Apple Watch owners by simulating a tap on the wrist by vibrating. The part is also used to transmit a user's heartbeat to other Apple Watch users. The Journal said that the initial delay in shipping out the product was due to the problems with the defective part, which has reduced the number of watches available to send out. This has forced Apple to limit sales to online orders and a small number of high-end retail locations. It has also pushed back the shipping date for some online purchases to as long as July.
The good news is that apparently, none of the Apple Watches containing the faulty taptic engine were sent out. "I believe no faulty Apple Watches were shipped to consumers. I don’t think this is damaging at all," said Patrick Moorhead, founder of Moor Insights & Strategy. So far, it would seem as though this assessment of the situation is right. We haven't heard from a large number of Apple Watch owners complaining that their new timepiece is defective. Apple Watch pre-orders started shipping on April 24th.
