CHAPTER 01
From jewelry to instrument
Small watches were worn on the wrist before the twentieth century, particularly as jewelry. The technical and cultural transition was making a strapped watch useful and acceptable for routine timekeeping in many settings. Legibility, shock resistance and how the crown was positioned were genuine design concerns.
Pocket watches remained dominant for many people. A change of location on the body altered how frequently the watch was read and how a person interacted with it.
CHAPTER 02
Aviation and the Santos
Cartier's own account dates the watch made for aviator Alberto Santos-Dumont to 1904. Santos-Dumont wanted to read the time while flying without handling a pocket watch. This well-documented story illustrates a wider need among people whose hands were occupied.
Calling the Santos the only or indisputable first wristwatch would obscure earlier wrist-worn pieces. Its importance is the combination of purpose, design and lasting influence.
CHAPTER 03
Why field use accelerated adoption
In military and outdoor work, a watch read with a glance could help coordination while equipment occupied the hands. During the First World War, widespread field use helped normalize wristwatches for men in societies where pocket watches had once been preferred.
The military association should not obscure commercial advertising, women who wore wristwatches earlier, or the role of civilian sports and aviation. Multiple streams converged in the early twentieth century.
CHAPTER 04
The modern watch takes shape
A durable case, legible dial, practical strap and reliable crown became standard ingredients. Later advances—waterproof cases, automatic winding and shock protection—made the wristwatch a more robust everyday companion.
Today the outline of a field watch, pilot's watch or dress watch carries traces of that history. The category name suggests an origin or aesthetic; it does not guarantee a particular watch has military or aviation certification.
Look closer
Cartier's historical account of the 1904 Santos-Dumont illustrates how function altered the design of portable watches.
A historical distinction: The Cartier Santos was an influential early purpose-built wristwatch, not proof that wrist-worn watches did not exist before 1904.
