That's @imagwai's issue to solve, I'm perfectly fine with a thinner 39mm glassbox Carrera.
Nothing to do with me! I don't want another 36mm reissue and am happy with 39mm glassbox too. But if they did do it, and they were going to charge top dollar like their other heritage pieces, what would be wrong with creating a new movement for it. Other brands, larger and smaller, do it all the time.
