CARTIER, PARIS, 18K GOLD SKELETONIZED MINUTE REPEATING KEYLESS LEVER ART DECO DRESS WATCH

This unusual timepiece is one of the exceedingly rare skeletonized minute repeating dress watches made by Cartier at the beginning of the 20th century, a fine example of one of Cartier's "couteau" dress watches, referring to the ultra thin case resembling a knife's edge.

It perfectly combines elegance and highest workmanship.
