Since watchOS 4, Apple Watch wearers celebrated the new year with a fireworks display on the screen. The feature is available for all Apple Watch models and it is a feature that you can only get once a year. To get this feature, update your Apple Watch to the latest version of watchOS, strap your watch on and wait until midnight. Your Apple Watch will let you know when 2020 rings in.
If you want to play the fireworks animation again, open Notification Center on your watch face by swiping down from the top and tap on the fireworks notification. This notification won’t disappear until after New Year’s Day in January.
