Changing the strap or bracelet can radically alter the look and feel of a watch.
While the Santos de Cartier on a bracelet is considered a more popular choice among Cartier watches, the Santos-Dumont closely resembles the original design created by Cartier for aviator Alberto Santos-Dumont in 1904. Recent versions of the Santos-Dumont have primarily featured alligator straps, emphasizing the watch's elegance and classic style. For mechanical enthusiasts, the choice was limited to only the Extra Large models and the skeletonized Large models equipped with a mechanical caliber with a micro-rotor. At Watches and Wonders 2026, Cartier unveiled a series of new Santos-Dumont Large models with flexible metal bracelets, hand-wound mechanical movements, and stone dials.
Dial: Innovation and Classicism
One of the key innovations in the new Santos-Dumont models is the choice of dial. In one of the gold models and the platinum version, a classic silver satin-finished dial with a sunray effect, Roman numerals, and blue hands is used.
However, Cartier keeps up with modern trends in the classic watch segment - one of the 18-karat yellow gold models features an obsidian dial. This volcanic stone is sourced from Mexico, and its pearlescent glow is due to microscopic air bubbles trapped within the material, making each dial unique. The obsidian dial is adorned with gold hour markers and hands, harmonizing with the gold case and bracelet. Silver dials feature black Roman numerals and blue steel hands.
The central part of the silver models is framed with a square that breaks the monotony of the large sunray dial. Special attention is given to the number seven on the Roman dial - it contains a hidden Cartier signature. In the version with the obsidian dial, the frame is absent, and the dark background and massive applied indices do not allow for a hidden logo.
Case: A Blend of Tradition and Modern Technology
The new Santos-Dumont lineup includes two models in 18-karat yellow gold and one in platinum. The case measures 43.5 mm in length, 31.4 mm in width, and 7.3 mm in thickness, with water resistance up to 3 atmospheres (30 meters). The case features a vertical satin-finished surface and polished bevels, with a bezel adorned with visible screws. The winding crown is equipped with the iconic Cartier cabochon: a blue sapphire for the gold models and a red ruby for the platinum one.
The case back is made of the same material as the case and is engraved with the Cartier logo, water resistance indication, and serial number. The press release also mentions two other gold models and a model in a combination of gold and steel, updating the existing collection.
Metal Bracelet: Inspiration from the 1920s and Modern Technology
The new metal bracelets are inspired by custom-made bracelets that Cartier created for clients in the 1920s. They have a silky smoothness and high flexibility due to their construction. Each bracelet link consists of 15 rows, with a link thickness of 1.15 mm, and the bracelet contains a total of 394 links. Manufacturing, finishing, and assembly of the bracelets take place at Cartier's production facilities.
The bracelet is attached to the case with traditional spring bars and secured on the wrist with a folding butterfly clasp. The material of the bracelet matches the case material, making the watch quite heavy despite its compact size.
Movement: Slim and Reliable Cartier Caliber 430 MC
The updated Santos-Dumont models are equipped with the Cartier caliber 430 MC. This hand-wound movement is based on the Piaget 430, decorated with the Cartier logo motif, displays hours and minutes, operates at a frequency of 21,600 vibrations per hour, contains 18 jewels, and has a power reserve of about 38 hours. With a thickness of just 2.1 mm, the caliber is ideal for maintaining the thinness of the case - a key parameter for elegant watches made of precious metals.
Conclusion: A Blend of Style, Comfort, and Reliability
Not all watch enthusiasts prefer leather straps. While they are comfortable and suit many models, especially after breaking in, in warm weather, leather can quickly lose its presentability and comfort.
On the other hand, large metal bracelets on classic watches often create a dissonance. A thin and flexible metal bracelet solves the problem of leather's durability and maintains the refined style expected from precious Cartier watches. The new Santos-Dumont models are sure to attract buyers looking for such watches. Their success could increase if Cartier expands the bracelet line by releasing them in stainless steel.
