I always thought that the case size of a 5970 is 42mm, which is the same as that of a 5070. But taking a straight comparison between the two watches, the case of a 5070 is definitely bigger and the lugs seem to be different as well. I think the case of a 5970 measures to only about 40mm (without the crown and buttons).
As such, despite of the dial differences of the two watches, it seems that both watches have different cases. Could someone please help me understand more on this?
Thanks
