I work with a 'watch guy'. He has multiple collector-grade watches, and others that he resells for $1k+. My response is always 'and how well does it keep time?' since that is the PRIMARY function of a watch/chronometer. I'll keep my basic plastic digital Casio F-105 from WalMart for ~$14. The Casio keeps better time than his $1500 Rolex Oyster Submariner (I don't even know if that is a thing, but you get the jist).... Even if I was bazillionaire, why would I wear something that keeps less-accurate time????
I will admit that I have my great grandfather's heavy engraved and inlayed silver-cased pocket watch - but that is in a display case... From what I've learned, BITD the case was sold separately from the movement, and mostly sold through jewelry stores. GGpa's watch movement is nothing special but I keep it for the case (and family history)...
