I acquired a speedmaster sapphire sandwich recently for cheap. I am not exactly sure what model is. After some research I think it is the Apollo XI 10th Anniversary. The watch had been sent to Omega for repair after water damage and looks outstanding. I have the dial that was on it originally (T Swiss T) but it has been replaced with a non T Swiss T dial. Also it is on a Omega logo 1171/1 bracelet and also came with another Speedmaster logo bracelet that says 1479 on it. My questions are which bracelet came on this originally and how much does replacing the dial hurt the watch? Can I get a T Swiss T dial to put back in it (used)? The one I have is in bad condition (the markers are worn off some and brown/yellow). Anyway anything anyone can tell me about this is appreciated (ref #, value, history etc...) There is no paperwork or box.
