Taiwan's Quanta Computer Inc will start mass production of Apple Inc's first smartwatch in July, a source familiar with the matter said, as the US tech giant tries to prove it can still innovate against rival Samsung Electronics.
The still-unnamed watch, which Apple followers have dubbed the iWatch, will be the company's first foray into a niche product category that many remain skeptical about, especially as to whether it can drive profits as growth slows in tech gadgets.
The production will be a boost to Quanta, whose work for Apple so far has focused on laptops and iPods, product lines that are in decline.
Quanta's role, though, is likely to raise questions about what involvement Hon Hai Precision Industry Co, one of Apple's biggest suppliers, will play in production.
While the watch has been widely expected, the start date of its mass production and the extent of Quanta's involvement were not known until now.
"Mass production will start in July and the commercial launch will come as early as October," according to the source and another person familiar with the matter. The sources requested anonymity because Apple's production plans are private.
Apple will introduce a smartwatch with a display that likely measures 2.5 inches diagonally and is slightly rectangular, one of the sources said. The source added that the watch face will protrude slightly from the band, creating an arched shape, and will feature a touch interface and wireless charging capabilities.
The source said Apple expects to ship 50 million units within the first year of the product's release, although these types of initial estimates can be subject to change.
The watch is in trial production at Quanta, which will be the main manufacturer, accounting for at least 70 per cent of final assembly, the source said.
Like many other smartwatches, Apple's watch will be able to perform some functions independently, but tasks like messaging and voice chat will require connection to a smartphone, according to the source.
The device will only be compatible with gadgets running Apple's iOS, like its flagship iPhone, one of the sources said.
Most mainstream smartwatches collect data about the user's heart rate and other health-related metrics, in addition to facilitating tasks like checking e-mail and making phone calls.
A third source said LG Display Co is the exclusive supplier of the screen for the gadget's initial batch of production. It also contains a sensor that monitors the user's pulse. Singapore-based imaging and sensor maker Heptagon is on the supplier list for the feature, two other sources said.
Apple declined to comment. Quanta, LG Display and Heptagon also declined to comment.
Apple's smartwatch will follow similar devices by Samsung, Sony Corp, Motorola and LG Electronics Inc - gadgets that tech watchers say have not been appealing or user-friendly enough to ignite a wave of mass adoption.
But the market is growing fast, with data firm IDC saying that worldwide shipments of wearable computing devices, including smartwatches, will triple this year over 2013.
Apple has already dropped hints of its plans in this arena, hiring the former chief executive of French fashion house Yves Saint Laurent, a unit of Kering SA, and proclaiming that it will introduce "new product categories" this year.
Many are hoping that Apple's entry into the field of so-called smart wearables will transform the industry like the company's iPhone did in 2007.
Some forecast that smartphone sales, the current cash cow of the consumer tech world, will lose momentum as the market reaches saturation. IDC predicts that worldwide smartphone sales will increase 23 per cent this year, slower than the 39 per cent last year, and that annual growth will average only 12 per cent from 2013 to 2018.
