'Watch'? For sure.
'Savant'? Super rarely.
What, knowing a few movement numbers and brand names makes one a "savant"? Or owning an Omega?
I don't think so.
You can lay claim to 'I' all you like, but if you want that 'S' you ought to be able to explain how every part of a movement works in a Horology 101 class.
AND, demonstrate how to take one apart, and put it back together again.
I propose the following replacement terms, in the name of honesty and humility.
But, speaking only for myself, more honesty than humility.
So then here are my new terms: (ADD YOURS!!)
1. WOG: Watch Obsessed Geek
2. WAD: Watch Addicted Dufus
3. WEF: Watch Enamored Fool
4. WOW: Watch Obsessed Wanker (or Wastrel)
5. WIG: Watch Idolizing Goon
