Thank you for posting the photo and creating an interesting debate. My preference is for the cleaner and more legible style of the 5170 although I prefer the leafed hands of the 5070. The smaller track and case of the 5170 make the face less cluttered. Love the numbers on the 5070 but sadly to my eye they add to the clutter. Diamonds have a poor reputation as markers but the 5170 doesn’t say bling to me.
