The 570 has this case shape I like very much and quite unusual (as very straight sides compared to rounder ones from the same epriod). I liek that specific feature.
The 3417 has a lot of charm, less strict.
Their classic side is different as well especially when having a look at the 3417's numerals' style.
They are only 3 handers but have so much things to tell.
The Top 5 is agood exercize to study watches 
Thanks Joe!
Cheers, Mark
