IMHO, erecting a sub forum called "Rolex & General Horological Discussion" would be a VERY good idea!
I would think that this sub forum maybe would be a little "quiet" to start with, but when members have learned of its existance I believe such a sub forum would really hit it off!
Mods could move questions and topics posted in the General Rolex Forum to this sub forum (like done with the WatchOut Forum) and thus create an unwritten rule that "here the questions and posts about technical topics belong - and can be found".
Excellent suggestion, Daniel!
