How to get more space on Apple Watch when nothing is used in the first place??

I'm extremely disappointed in Apple's

I can't install the software update, it says it requires 700+MB of RAM... however I literally have as little as I can on my watch!

Here's what I have in usage:

Software Update: 341MB

Music: 308MB*

Photos & Camera: 30.2MB

... (the rest are all smaller than 30MB)

I'm assuming you can't install the update if you delete that... so what other options do I have?

Music is taking up 308MB, however, I literally have no music stored on this thing! No "automatically add" playlists, and "Playlists and albums" is completely blank! so I guess 308MB is for the app which I can't use (because I have no space anyway) but it's still not enough to install the update?

Photos it looks like requires a minimum of 25 photos (there's no "photos limit' of zero)... literally no way to remove those, I guess.

I thought the Series 3 watches would last longer than this before they were rendered un-updatable...

Sincerely,
