Ulysse Nardin Perpetual Ludwig

hey all it is time to move on my UN Perpetual Ludwig to the next person. this is the yellow gold version which is a numbered limited edition of 150 pieces made to commemorate the 150th anniversary of ulysse nardin. folks here would know that this was the first watch containing ludwig oechslin's perpetual calendar module. one of the most user-friendly perpetuals around, even today. the watch has no dings or nicks and is keeping time very well. comes with box and warranty card. i am asking USD13,100 or SGD17,000. the watch is in singapore and would prefer a face to face transaction but i'm willing to ship worldwide but we have to discuss cost of shipping and insurance. please pm me if you are keen. thanks!
