Here's how much the Apple Watch Series 4 will cost you

It's finally here. Apple announced the Watch Series 4 at its big event in California on Wednesday, and it's just as great as we'd hoped.

Apple says it will start taking pre-orders for the GPS and cellular versions on Sept. 14, most likely around 12 a.m. PT / 3 a.m. ET.

The Watch Series 4 will officially be available in stores on Sept. 21.

An Aluminum Series 4 40mm with GPS is $399 and the 44mm is $429. If you want cellular connectivity, you will add $100 to the price point. The higher end Gold Stainless Steel Series 4 is $699 and $749 for the 40mm and 44mm sizes, respectively. There is no ceramic or gold Apple Watch Edition version of the Series 4.

Apple has not announced every carrier that will offer the Series 4, but we expect it to be available on most major U.S. carriers including AT&T, T-Mobile, Verizon, and Sprint.
