Looking to get an Apple Watch when it officially goes on sale April 24? You may already be out of luck.

The launch of the Apple Watch began Friday morning at 3:01 a.m. New York time as preorders for the device became available to eager consumers. But after a few hours, many versions were already unavailable for more than a month, with most models shipping in four to six weeks.

In an attempt to avoid the tradition of long lines at Apple Stores wrapped around city blocks, the watch is only available for purchase online “for an initial launch period,” according to Apple. It’s not clear how long this period will last.

Customers will still be able to visit Apple Stores beginning today to see the watch in person.

Apple recommends that interested customers make a reservation online to see a sales rep at the store of their choice, which also began Friday morning.

Long Islanders hoping to buy the 18-karat gold luxury models known as the Apple Watch Edition will find their options even more limited.

Select Apple Stores in the country will stock the Apple Watch Edition, which starts at $10,000 and can go as high as $17,000.

The closest stores authorized to sell the Edition will be three in New York City: Apple’s Fifth Avenue, SoHo and Upper West Side stores.

Apple’s Long Island stores won't carry the luxury version of the watch, leaving the four locations that include stores at the Walt Whitman Mall in Huntington Station, Roosevelt Field in Garden City, Smith Haven Mall in Lake Grove and a stand-alone Apple Store in Manhasset with only the more basic models.

The three versions of the watch include an Apple Watch Sport model starting at $349; the standard Apple Watch model starting at $549; and the 18-karat gold Apple Watch Edition starting at $10,000.
