Apple Watch has 8GB of Storage
Apple has confirmed that there is 8GB of storage on the Apple Watch. They have also outlined what that space will be used for. 2GB is dedicated to songs that will be stored directly on the watch. 75MB will be dedicated to photos. However, if the watch is connected to an iPhone then you will have an unlimited space available for photos and music, as it’s just pulled from the phone. That size is for music and photos stored directly on the watch. The remaining space is said to be for the device’s software and other application files. What’s not known right now is if applications downloaded from the Apple Watch App Store will be stored on the watch or iPhone.
