Anyone can own a R***x, an Omega, Breitling, or a Seiko for example, and `anyone` would probably be familiar with them, but which watch in your collection would you consider to be the one that confirms your status to be a `WIS`?
The one that is probably totally unknown to the general public should it come up in conversation?
The one which might strike up a conversation with another watch fancier should their gaze rest upon it?
The one which only another watch nerd would recognise?

Vintage stuff notwithstanding I suspect a lot of micro brands will be mentioned..
