KL670
As a long time fan of Glashütte Original since my first PuristS on Tour visit to their factory in 2003, please may I post a few thoughts?
The two watches you are comparing are like Yin and Yang although its hard to say which is which.
One is elegantly discrete and the other a bit showy and brash.
Soft and Hard.
One will garner the odd comment from onlookers and the other won't.
Personally, I like my blue bits and engravings on the backside.....only for me to see.
I get to wear the watch anywhere, without comment, but still can enjoy the exquisite craftsmanship inside.
Regards,
MTF
