With related yield rates significantly improved, the Apple Watch is expected to see a significant shipment growth in the second half of 2015, boosting the revenue performance of the device's manufacturer Quanta Computer, according to sources from the upstream supply chain. As for recent market rumors that other manufacturers may land some Apple Watch orders, the sources believe the chance is slim since shipment volumes have not yet reached a level that requires multiple suppliers to reduce risks.
DigiTimes notes that there is a large discrepancy in estimates for Apple Watch shipments with some supply chain estimates at 40 million units for 2015 and market watchers estimating 9 million units.
Supply chain players are reportedly monitoring the performance of Apple's smartwatch and are preparing for a possible surge later this year.
Notably, Apple has yet to expand Apple Watch sales to reach all the countries where you can buy the iPhone.
