The Apple Watch will be available to buy in seven more countries, but not Ireland, from June 26.
Customers in these countries will also be able to buy the Watch in-store from the same date.
Until now the Watch has only been available online, with limited stock in some fashion boutiques who partnered with Apple for the launch.
In countries where the Watch has already launched it will begin to be available in-store "in two weeks" - around June 18.
The Watch will also go on sale in what the firm calls Apple Authorised Resellers.
Jeff Williams, the Cupertino-based firm's senior vice president of operations, said: "The response to Apple Watch has surpassed our expectations in every way, and we are thrilled to bring it to more customers around the world.
"We're also making great progress with the backlog of Apple Watch orders, and we thank our customers for their patience. All orders placed through May, with the sole exception of Apple Watch 42mm Space Black Stainless Steel with Space Black Link Bracelet, will ship to customers within two weeks. At that time, we'll also begin selling some models in our Apple Retail Stores."
The Apple Watch first went on sale in April but used a very different system that removed the traditional queues outside the company's official retail stores around the world on launch day.
Instead, users were encouraged to buy online, and those who visited a physical store had to make appointments to try on a Watch before again making the purchase via Apple's online platform and having it delivered to them.
No date has been given for when the device will be available to customers in Ireland.
