What's your preferred size of collection?

I usually have a core of <6. Any more, and it's hard for watches to naturally get enough wrist time. Of course, you can make an effort to cycle through larger collections, but it feels more forced to me. I've noticed that when my collection grows to the 8+ range, I tend to have multiple watches that fit into similar niches and I usually have a favorite between them. For me, 5 or 6 is plenty to cover different outfits and situations and have enough variety to not get bored.

I think even going down to 2 would be potentially doable (one dressier, one more everyday), but it's fun for me to have a little bit more diversity.
