The present model is an indelible part of Cartier's history, and represents what the brand is best known for: merging form with function. A variant of the original Tank wristwatch, the Tank à Guichets was first introduced in 1928. Featuring jumping hours at the upper portion of the dial, the watch also displayed a minutes indicator at 6 o'clock. The Tank à Guichets was first released in 1928, evolving from the first Tank model of 1917. The watch was a modern masterwork of design, where less is more. Gone are the hands, and in their place ‘guichets’ – apertures – for the hours and minutes. Its name derives from the apertures, which "jump" as the time advances. "Jump Hour" wristwatches were particularly popular in the 1920s and 1930s.

Made in Paris (as seen by the European Watch and Clock Co. Inc France engraving on the caseback), the present watch cased in white gold is an exceptional specimen .The case is remarkably well-preserved, exhibiting strong hallmarks and crisp numbers throughout, and displays the maker's mark "EJ" and French hallmarks. The condition of the timepiece is especially remarkable when one considers the age of the timepiece.
