I've been looking at a couple of 1920's era Gruen watches, specifically the quadron models, that I really like. However, on a couple of them the radium lume has been been replaced with an updated super luminova paste.
Even if it's well done, does that negatively affect the price? To be clear I am not a collector/trying to preserve this watch; I like the idea of keeping a nearly-100 year old watch running and in use as long as it can go, not preserving it in its original condition. That being said, it's not like I want a complete frankenwatch, either. The price on this one is around $750 to $800; though other unrestored versions have gone for less. Any information would be appreciated!
