Roberta Scarpa Automatic with Retrograde Seconds Hands RS6029

Roberta Scarpa is an artisan and fashion designer from Venice (born in La Serenissima). Started in 1981 with her husband, she launched her first collection under her own name in 1996. Her designs take inspiration from details of Venetian history, and she presents her collections through Milano Moda Donna, and won designer of the year in 2005 at Miami Fashion Week.
The watch has the highest original list price of any of my watches (63,000 yen), but is often seen at highly discounted prices - so I didn't spend very much ;-).
The watch itself is a 3-hand dial watch with an automatic mechanical movement. It has a dual time function with a small dial near the 12 o'clock position able to show an alternative time - when the crown is pulled out, turning anticlockwise, changes both dials together, while clockwise only changes the small dial. On the face are also 3 other dials, but these are retrograde (or jump-back) dials for the seconds. Each one covers 20 seconds, and then jumps back to the start as the next dial begins to move.
The model number is RS6029, and the movement may be made by Citizen (as I got a Citizen guarantee card in the box, but this being second-hand, I'm not 100 % certain).

UPDATE: I've now added a YouTube video of the watch in action: YouTube Link
