Roberto,
I agree with you to 100%. These watches should be easy to read in any conditions. Unfortunately negative faces in general are much harder to read and
Suunto Core watches are no exception. Dark orange on black is simply not a good combination if visibility is of any importance... As a matter of fact "hard to read the display" is a quite frequent complaint in various forums discussing these watches with negative faces.
Note! All
Core watches have the exact same functionality (same watch different color scheme and material) so you could try exchanging your Black Orange for a Light Black...
