Cartier dates the Santos-Dumont’s origin to 1904, when Louis Cartier made a wristwatch for aviator Alberto Santos-Dumont to help him tell time while flying. Cartier describes it as “the first modern watch specifically designed to be worn on the wrist.” That is Cartier’s own priority claim—not independent proof that it was the first wristwatch or the first pilot watch ever made.
Why Santos-Dumont wanted a wristwatch
Cartier’s account begins with a practical problem: Santos-Dumont wanted to read the time while flying. A watch worn on the wrist offered access without having to take out and handle a separate timepiece. Cartier’s current product history states: “1904. Louis Cartier granted the wish of his friend, the famous Brazilian aviator Alberto Santos Dumont: to be able to tell the time while flying.” This is Cartier’s account of the commission, not a quotation from Santos-Dumont or Louis Cartier.
The aviation connection is the reason this watch belongs in the history of pilot watches. The evidence supports describing it as a wristwatch made for an aviator’s practical need; it does not establish that Cartier or the original owner classified it as the first “pilot watch.”
1904 origin and the reported 1911 launch
The dates refer to different stages of the story. Cartier dates the commission and creation to 1904. A university-hosted research document reports that the watch was officially launched in 1911 with a design similar to the original. That secondary account gives context for the later launch; it does not negate Cartier’s account of a 1904 origin.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
These sources do not independently establish a universal first for wristwatches or pilot watches. Cartier’s collection page calls the Santos “the first modern watch specifically designed to be worn on the wrist,” while its current product history uses the more qualified phrase “one of the first ever wristwatches.” Both formulations should be attributed to Cartier rather than presented as settled historical rankings.
The design language Cartier carries forward
Cartier describes the Santos form through its geometric case, rounded dial angles, a seamless curve from case to horns, and exposed screws. Those elements connect the current Santos-Dumont family with the design language Cartier associates with the watch’s history. Cartier’s collection includes small, medium, and large models.
