Hi folks!! This is my first (hope, not last) post in this extraordinary forum. Eventhough I´m a vintage wristwatch fanatic , those for the 70´s are not of my particular taste (sorry guys); exception being some incredible pieces like this Heuer Autavia that I recently trade.

I´ve been searching in this and other forums about their history but there are a couple of questions that I would like to ask

a) this reference 11630 HS is considered an "orange boy" or "Gulf" or the nicknames are only applied to the reference 1163?

b) Although externally the watch is in mint conditions (the movement however requires a professional service ), the bracelet is dirty and has some minor scratches .

In your opinion and from the historical (not monetary) point of view, if I decide to buff it out this is considered by you experts a sacrilegy.?

Thank you in advance for your opinions and responses
