Ulysse Nardin Acqua Perpetual Calendar 333-77

I am offering for sale my Ulysse Nardin Aqua Perpetual. 42 mm stainless steel case with 14mm thickness. 300m water resistance. The watch comes with stainless steel bracelet with diver extension and additional rubber strap. The watch features amazing Ludwig Oeschlin’s design which makes adjustment a perpetual calendar as easy as a regular date: there are no correctors, everything is set via the crown. The date can be adjusted back and forth, so there is no danger of “overschooting”

The watch was purchased 9 years ago from Time Tunnel in Japan and was last serviced about 4 years ago by European Watch Company in Boston. It is in excellent condition: there are no deep scratches, dings etc. Bracelet and clasp have hairline scratches consistent with normal, careful wear. The watch comes with inner and outer boxes (the lining of inner box is flaking from age) and some papers. Extra rubber strap is still sealed. The bracelet is full length (including 4 links).

The last retail was around $29000. I am asking $7700 which is cheaper than anything I could find on the web by a wide margin. Payment by wire transfer. Numerous references available.
