Please forgive me, I'm new to this (discussion groups,horology,etc.). I don't want to come across as rude...I'm just ignorant/clueless. Have any of you heard of this A L'Emeraude Lausanne 8 days auto clock? Can someone tell me how to find out anything at all about it...or if it's even worth looking into. I've tried jewelers, books, now internet...There appears to be a number 15 on the back. I don't know how or if I should try to take it apart... Thanks. Again, my apologies...
