The U21 interprets the uniquely structured A-250 in-house caliber in a noble metal case. It combines the bezel-less carbon fiber central case element with polished and satin-brushed 18-karat rose gold lugs to enhance its visual appeal. The skeletonized bridges are also 18-karat rose gold for additional harmony between the case and movement. To further enhance legibility, the hands are filled with white Super-LumiNova.

The U21 makes a tremendous impact. Materials, shapes, and structures are arranged to create an elegant, technical, and finely honed timepiece. Measuring 42mm in diameter and 10.3mm thick, the case mixes 18-karat rose gold lugs with a CTP caseback and middle. The rich-looking rose gold and the technical appearance of the carbon fiber inject the U21 with visual energy. Meanwhile, rose gold bridges hovering above the CTP main plate put this piece in a class of its own.
