collecting watches is individual syiok sendiri hobby
just like collecting any other thing
you are collecting wide range of watches
some people just concentrating in
single purpose, ie dive
1 brand
single color dial
1 model but all generation
etc
i have seen people with all version of omega speedmaster
pre moon, mk1, mk2....... mk5, modern speedmaster professional and all limited edition...
so really depends on what you want, what you like... not others
