If you're planning on buying the new Apple Watch, don't expect to walk into a store and leave with one next week.

Apple, which began accepting advance orders for the watch last week, had previously said that it would be available for sale in stores on April 24. But with supplies limited, Apple's retail chief told store workers this week that the watch will continue to be sold only online for at least the next several weeks.

Apple stores have the watches on display, and the company is still offering in-person demonstrations for customers who want to try different models. Apple says customers who placed early orders will have their watches delivered starting next Friday, although recent orders could take several weeks to fill.
