Apple just made a surprising change to how it ships the Apple Watch SE. It now comes with a USB-C cable instead of USB-A.

With the Apple Watch Series 7, Apple is now bundling a USB-C magnetic charging cable when you purchase a new watch. But interestingly, if you go and buy a brand new Apple Watch SE from Apple, the company will now give you a USB-C magnetic cable instead of a USB-A one. Surprisingly, the Series 6 and Series 3 still come with the older USB-A cable for charging.
