Both sides are sensational, but the engraved and skeletonized verso side completes this watch as a concept. With either side, you see exquisite engineering and the watchmaker's skill of assembly, but the skeletonized caliber and intricate engraving on the reverse elevate the watch to the level of freehand fine art. Thusly equipped, no two will be alike, the concept is complete, and the Tribute is a masterpiece on all levels,
