Nomos had a "brown gold" watch a few years back I always thought it was a really nice looking watch I think its discontinued now.
Very good review of this watch OP I think your detailed photos show that there is a decent level of finish to the watch. I am not really a fan of the the applied numerals and batons but thats just my taste its otherwise a good looking watch. I think you also did a review of one of their other watches with micro rotor?
