The Backs
The two from the back, the very well polished SKX419 (left) was quite hard to photograph decently, so I moved it into the shade. The SKX007K2 is a bit burnt, but since the plastic foil that covered the new watch is about to fall off, I did not mind to hide those residues a bit. The SKX419K shows a simpler wave logo, the SKX007K2 shows the newer bigger wave logo. The same logo is found at the free end of the strap on both watches
