I just got this Ulysse Nardin.
" 10k Gold Filled D&A" marked on the back.
New glass and leather strap.
Works perfectly, keeps time. I love it so much, I always wanted some vintage watch, but I didn't know where to start. This one came unexpectedly, maybe a gift to myself for my birthday ( in a month...big 40! ). :)
If someone knows more about this model I would appreciate if can share some info.
