Casio GuySo I recently discovered WatchCrunch. Not sure there’s a need for this Masto instance now? There’s so much more more discussion on there.
WatchCrunch – A home for watch nerds.
WatchCrunch is a place for watch lovers to discuss, share, learn, and geek out about watches. Like you, we LOVE watches! We believe watch discussions should be fun and inclusive, not snobby and intimidating, so whether you're a seasoned veteran of the watch world or an absolute beginner, come join the conversation.

I have some doubts as to whether each and every theme is enough to create another 
instances.
