Question about "originality"

[Barnaby]

I've just 1970s Oris Star with the intention of servicing/restoring it and selling it on. It has no crown.

I can either buy a generic, unsigned, crown for about £2,

OR

buy an Oris signed crown for about £20.

Would installing the Oris crown significantly (i.e. more than £18) increase the value of the watch, bearing in mind that it is not original to the watch?

[Nucejoe]

Much depends on the condition of the watch, if all else is like new, a new signed crown would be enhancing, even being not original to the watch. 

Pix help giving more evaluated opinion.

If it is not original to that watch then no. Collectors want original.   This is a movement out of an Oris Star Gents watch. It is not a very good movement, quite poor compared to to others. Is yours the same?

I'm no expert on reselling watches—I keep all mine—but, you can't go wrong with a new crown.
