Prada's limited edition timepiece houses a face that is carved from a photoelectric cell that needs only a small dose of sunlight to stay powered for a month. It even has a radio receiver (Unfortunately this only works in Europe) that will automatically adjust the time for you (hough you have to manually adjust when the clocks go back/forward).

A limited edition with IWC this is numbered 186/1000.

Sold originally as a man's watch but worn previously by my female client. Originally sold with a different strap and replaced with a black saffiano (Prada) one by the current owner. The strap shows some wear but the watch is in perfect condition and fully functioning, despite some very light scratching to the bezel.

Comes with the original box, case and instruction book.

Size/Dimensions: case 44 mm; adjustable bracelet strap 14 - 19.7 cm (51⁄2 - 73⁄4in)
