NMK305 blue AR - great

I swapped crystals in my trusty skx (with existing namoki bezel insert) - really happy with this one. Old hardlex was looking a bit cloudy, now she's better than new. Did the job with a cheap crystal press - had just done my srpe61 (my first crystal swap) and the skx was even easier!! Cheers, Namoki!
