How does replacing a clasp affect resale?

[Brovsko]

Hi Gents,

I was wondering if anybody could shed some light on how replacing a clasp may affect the resale value of a particular piece. Obviously a new clasp may not correspond to the same year as the watch so would this be seen as a 'frankenwatch'? I'm speaking specifically about purchasing a clasp directly from Rolex.

Thanks in advance for any insight.
