**Twenty~4 Small Haute Joaillerie Ref. 4909/50** is an elegant ladies watch by [[Patek Philippe]].

The Ref. 4909/50, presented on the [[Baselworld]] in April [[2003]], enriches the Twenty~4® Haute Joaillerie collection with a model with mechanical [[movement]]. This Twenty~4® Small differs from the other models by the rich diamonds on case, dial and bracelet, and the mechanical movement.

The watch is available in 18ct rose or [[white gold]] and is set with 1468 [[diamond]]s of the highest quality "Top Wesselton Pur" , a total of about 8.33 carat. Even the caseback is set with 104 [[diamond]]s and also equipped with a [[sapphire crystal]], which allows a view of the mechanical movement calibre PP 16-250 with [[manual winding]]. This movement, like all mechanical Patek Philippe watch movements, is provided with the [[Geneva Seal]], which is considered as the highest official award of quality watchmaking.

The elegant and functional Ref. 4909/50 has hands and two Roman numerals at 12 and 6 o'clock in black oxidized gold to ensure an optimal reading of the time. As a special highlight a [[brilliant]] adorns the crown of the jewelery watch.

Design and shape of the new Small Haute Joaillerie remember of the original model of the Twenty~4® from [[1999]], which was created to adequately accompany modern, style-conscious women at all hours and occasions. The most striking features of the latest creation are the stunning [[diamond]]s on case, dial and bracelet, and the mechanical movement.
