Apple had directed people to order online, preventing long queues around its stores that have become a norm with the company's rollout of new products.
               
"We believe making the Apple Watch available for customers to purchase at an Apple retail store will drive increased sales volumes," Cantor Fitzgerald analysts wrote in a note.
               
The company said all orders, except one model, placed through May would be shipped to customers within two weeks.
               
"The response to Apple Watch has surpassed our expectations in every way," said Jeff Williams, senior vice president of operations. "We're also making great progress with the backlog of Apple Watch orders."
 
The company has not given any sales figures for the watch since it began taking orders, but has often said demand was outstripping supply.

Apple Watch will be launched in Italy, Mexico, Spain, South Korea, Singapore, Switzerland and Taiwan on June 26, the company said. The watch is currently available in the United States, Australia, Canada, China, France, Germany, Hong Kong, Japan and the UK.
               
Apart from online stores, customers in these countries can also buy the devices at Apple's retail stores and some authorized resellers.
