Very nice set of GMTs! Your picture beautifully illustrates the diversity of this model!
Up until recently I was not that much into GMTs. Ok, I always had one in my collection but did not wear it much. Then I got my 16760 some months ago and that quickly became my "everyday sparetime watch".
And just last night I ventured 400km through deep snow in Switzerland to fetch my latest GMT: a 1675 from 1960 with pcg and rail dial. Pictures will come once the sun returns!
