Reference E857. Calibre K815. Production/delivery year: 1959. And, my DSA comes on the original LeCoultre flex metal bracelet. And, I dare to say: it is in incredibly good condition. Cheers, HSTE ...
this was a factor for me to let pass many DSA's over the years since they looked as if they had gone multiple times through a cow's stomach. I dare to say that this one is probably one of the best preserved specimens around. Cheers, HSTE
