I have also seen many people bring up the sentiment that only having watched in one’s collection that you wear and use for it’s intended purpose, and my own collection reflects this for various reasons, but I don’t think it’s the only or best way to build a watch collection. 
 

people collect coins but don‘t buy things with them. They collect stamps but don’t mail things with them. They collect sports jerseys but don’t wear them. 
 

I think the spirit of collecting is something that doesn’t need an explanation. If it brings you joy, and you find pleasure in having a large collection of pieces that fit your collecting mindset, then you should do that! 
 

the biggest reason my watch collection is smaller at the moment is because I have bought many watches that I thought I would like because they were similar to the watch that I wanted. Eventually I lost excitement for the watch and would want the watch I originally fell in love with. Now I save until I can afford the watch I want. But that’s my own personal journey with collecting. I like unique and less common watches, but somehow the ones I love are still in the $1000-10,000 range, so I shall continue saving.
