It’s a weird thing that they seem to want to not use other materials in the 42mm size.
I actually hallucinated a blue dial titanium Speedmaster Pro existing in the era of the chocolate dial Sapphire Sandwich but no. They made the Solar Impulse GMT in titanium and based it on the 44.25mm Speedmaster Coaxial, they made a blue dial Cal 9300 Speedmaster Coaxial also in that larger size, and that is what I think I was confusing the Moonwatch with.
But there is no titanium 42mm Moonwatch, no ceramic 42mm Moonwatch, only steel or precious metal.
The closest is the Apollo 11 45th Anniversary, though even that was two tone with no bracelet.
I remember reading Chuck Maddox post about how good it would be to have a titanium normal Moonwatch like the 2298.80 he loved, it’s strange that all these years later it still hasn’t happened.
