The GMT version of the updated Oris BC3 comes as a limited edition done for the Oris Big Crown Sky Racing team. Why does “Big Crown” need to be in that term? I know that Big Crown is a line if watches from Oris, but does that mean there are other Oris Sky Racing teams? Anyhow – that BC3 Air Racing Limited Edition watch comes in the same 42mm wide case as the BC3, but here in titanium. It also has a special red ring about the crown to go with the GMT hand.
