On the other hand, if this happened with Panerai's, Paneristi's are mad crazy and die-hard so any little difference like this will be blown up into huge proportions and affect secondary mkt prices IMO.
With RM, there isn't enough of a fanatic crowd for slight changes to affect secondary pricing IMO.

I'm sure this has been raised before and I'm sure somebody said they are changed to clear when the watch is serviced unless you specify you want them to stay red. This would suggest it is purely cosmetic and won't affect the future value.
