I have heard the statement that they didn't want to re-issue too close to the original to protect the owners of vintage versions. That sounds like bs to me.
I have the 1964 Carrera re-edition and it is almost identical to the original.
They have bulked this up to fit with current fashions and in the process spoilt it.
I have tried one one and wanted to like it but it was just too big.
Also, the 2 1/2 markers on the minute sub dial are a very odd choice. Why not minute markers like the original.
I haven't seen one in the flesh, but the comments above sound very much like my own views; if it's too big it's not going to work for me.
Why not stick to the original dimensions and so the reissue thing properly?
