The Apple Watch uses a MagSafe-style wireless charger. It magnetically attaches to the back of the Apple Watch and is then charged inductive. Although it works in the same way as existing wireless chargers on the market, wireless charging can still bring a lot of convenience for a device that may need to be charged every day. Apple doesn't disclose the battery life of the Apple Watch, but judging by its colorful and bright display, the device probably does need to be recharged regularly.
