The Cartier Tank Normale Skeleton Dial reference WHTA0021 is a high-end luxury watch from the Cartier Privé collection that pays homage to the original 1917 Tank design. This large model features a rectangular case crafted from 18k yellow gold measuring 35.2 mm in height, 27.8 mm in width, and 8.15 mm in thickness. The case is equipped with a beaded crown set with a blue sapphire cabochon and a sapphire crystal that is beveled to mimic vintage aesthetics. It is paired with a brown alligator-skin strap and an additional green alligator strap, both secured by a yellow gold ardillon buckle.
The timepiece is powered by the manufacture caliber 9628 MC, a manual-winding mechanical skeleton movement composed of 150 parts. This movement features an innovative 24-hour complication where the hour hand completes a full rotation once per day. The openworked dial is designed with a sunburst effect across the bridges, which function as a day and night indicator; the top half represents daylight hours with sun-shaped bridges, while the bottom half indicates night with crescent moon accents. The movement operates at a frequency of 21,600 vibrations per hour and provides a power reserve of approximately 36 hours.
General reviews of the Tank Normale WHTA0021 emphasize its role as a refined collector’s piece, highlighting the successful modernization of the historical “Normale” silhouette. Critics and enthusiasts praise the intricate skeletonization and the unique 24-hour display, which adds a sophisticated twist to a classic design. While the watch is noted for its exceptional craftsmanship and limited production of only 50 numbered pieces, some reviewers point out its lack of water resistance and high price point as factors that reinforce its status as a specialized dress watch rather than a daily wearer.
