Both fantastic watches and visually very different.
Will you wear them both regularly?
Will you find setting them tedious after time?
Is it important to you for the calendar functions to be set accurately if you are throwing the watch on for a night?
The 5270 has a manual movement so a winder is not an option.
I have learned that as much as I appreciate the beauty of a manual wind movement, I favor the practicality of automatic winding. the micro rotor 240 movement in my 5940 strikes a nice balance.
The 5270 is classic Patek and stands above.
