They were probably trying to be true to the size of the watch that Dave Scott wore on Apollo 15. So no, I don't think the smaller size would have broadened the appeal, since the appeal is primarily about the connection with the moon.lol.. sorry m8 ... yeah the moonwatch is a big watch.. I can wear it thanx to 8" wrists but I think bulova would have been way better off making it a 42mm watch.. they probably would have sold 2~3X times as many of them?
You're right, the original was probably about 43.5mm in diameter. The difference in size was presumably to achieve the same dial proportions with a different movement.I'm pretty certain that the original was smaller - can't seem to verify that at the moment though so who knows.
I suspect that's a low priority for them.hopefully bulova can be convinced to make a smaller equivalent movement to allow for some 42~mm chronos
