Kuo notes that Apple may reveal more details about the Apple Watch before its official launch, revealing specifics on battery life and the start of pre-orders. Most components of the Apple Watch will see high shipments during the quarter, but other key components are expected to see low production yields which may cause a constrained supply. Kuo predicts that Apple will ship 2.8 million Apple Watch units in Q1 2015, and his estimate for a March launch falls in line with previous reports.
