Like you, I am not fan about the Date, in general, and this Watch is no exception.
Now, about the case, I am currently thinking that 34, 38, 39 mm are great MUT cases. Above, JLC should switch and adopt the case for the new Master Control line.
Back to the real MUTs, 38 and 39 mm are two different cases, if you look at their respective profile.
I euqally love both of them.
Best,
Nicolas
