Apple limited availability of its smartwatch after a key component supplied by a Chinese company was found to be defective, the Wall Street Journal reported yesterday, citing people familiar with the matter.
The component, called the taptic engine, produces the sensation of being tapped on the wrist, the newspaper reported.
Apple declined to comment on the story.
Apple has not given any sales figures for its hotly anticipated Apple Watch since it began taking orders this month. CEO Tim Cook said on Monday that demand continued to outstrip supply.
Some taptic engines supplied by Shenzhen, China-based AAC Technologies Holdings started to break down over time, the Journal said, citing the people. The company is one of two suppliers of these components to Apple, it said.
As a result, Apple is now sourcing nearly all of its components from the other supplier, Japan's Nidec. It may take time for the company to increase production, the people told the Journal.
The Journal said an AAC spokeswoman declined to comment on the company's customers. Reuters was unable to reach the company for comment outside of regular business hours in China.
Nidec was not immediately available for comment.
