Cannot update apple watch due to lack of space (want to delete mail and Camera&photos app)

I have continually had trouble updating my apple watch due to lack of storage space since I got it. I have only synched 3 new apps and deleted all other ancillary preloaded ones that I can. Looking at my usage it seems some of the preloaded, "non-deletable" apps such as camera & photos, mail, and contacts are taking up the majority of space but I don't need them on my watch.

I have set the photos> selected photo album to none

I have set mail> include mail > to an empty mailbox (it makes you choose at least one)

I can't even find contacts on the watch it just shows up on the iphone companion app as taking up space

Also tried unpairing and restoring from backup but this just added more apps.

Any help or suggestions? Thanks!
