Cartier Santos-Dumont Extra Plate (Pre CPCP)
The Cartier Santos Dumont Extra Plate Ref. 821054 in 18k yellow gold is a refined interpretation of one of the maison’s most iconic designs. Measuring 27 × 36 mm, the slim rectangular case emphasizes elegance and proportion, paired with a white dial featuring Roman numerals that reinforce Cartier’s unmistakable aesthetic. Powered by a manual-wind movement and fitted on a leather strap with a tang buckle, this Extra Plate variant offers a particularly thin and graceful presence on the wrist.
Excellent vintage condition with very minor wear
Rooted in the original Santos design of 1904, the Santos Dumont line represents Cartier’s most classical and pared-back interpretation of the model. By the 1990s, pre-CPCP examples such as this one maintained a focus on thinness, proportion, and traditional craftsmanship, preceding the more formally defined collections that followed.
The “Extra Plate” designation highlights the watch’s slim profile- a defining characteristic that elevates it firmly into dress watch territory. Without the added visual weight of an integrated bracelet, the design feels lighter and more architectural, allowing the case shape and dial layout to take center stage.
Today, pre-CPCP Santos Dumont models are increasingly appreciated for their purity and understated execution. This reference captures that essence- a watch defined not by excess, but by balance, heritage, and enduring elegance.
