There are several things about the 5070 that I don't care for.
1. The arabic numerals on the dial, some of which are cut off
2. The case seems oddly proportioned--width to height
3. The case is a bit large at 42mm unless you have a large wrist.
4. The wide stepped bezel is not as interesting as the concave bezel found on the 5970
What I like best about the 5970 models.
1. Case size is perfect in my opinion at 40mm
2. The contrast of the charcoal grey baton markers and hands on the G model are spectacular
3. The beauty of the manual wind movement with chrono function is outstanding
4. The classic look of the dial layout
5. The concave bezel
6. The vintage look of the lugs
