While the original Apple Watch has a 2-meter charging cable in the box, Apple says new Apple Watch Series 2 and Series 1 models come with a shorter 1-meter charging cable in the box.
Apple Watch Series 2 models also include a 5W USB Power Adapter in the box, while Series 1 models do not. The wall charger costs $19 on its own.
Both new series became available for pre-order today, with shipping estimates quickly slipping to 2-3 weeks or later for most models. Best Buy still promises launch day delivery for some models.
