Kathmandu: Have you ever wondered why most people wear a watch on the left hand? It’s not just for convenience; the reason is deeply rooted in history, science, and practicality. In this article, we’ll explore the journey from pocket watches to modern wristwatches and how the tradition of wearing a watch on the left hand evolved.
Early Days: Pocket Watches
In the beginning, people didn’t wear watches on their wrists. From around the 16th to the early 19th century, watches were primarily kept in pockets. These were called pocket watches. Due to their large size, heavy weight, and complex mechanical construction, it wasn’t practical to wear them on the wrist.
Pocket watches were fully mechanical, containing delicate parts like gears, springs, and balance wheels. They had no batteries or automatic mechanisms, and even a small jolt could damage them. Keeping a watch safe was a challenge. Men usually carried them in a coat or trouser pocket with a small chain attached for security.
Why Was the Crown Placed on the Right?
Mechanical watches required regular winding to store energy in the spring. This was done using a small knob on the side of the watch called the crown. Watchmakers placed the crown on the right side so that users could easily wind and set the time using their dominant hand. When a watch was worn on the left hand, the crown was easily accessible without removing the watch.
The First Modern Wristwatch
It wasn’t until the early 1900s that men started wearing wristwatches. The first modern wristwatch was reportedly made in 1904 by Louis Cartier for his pilot friend Alberto Santos-Dumont. During flights, it was inconvenient to check a pocket watch, so Cartier designed a watch that could be strapped to the wrist. This innovation laid the foundation for men’s wristwatches.
After this, brands like Cartier standardized the right-side crown design, which is still common in mechanical wristwatches today.
First World War and the Rise of Wristwatches
World War I (1914–1918) further popularized wristwatches. Soldiers needed to check the time frequently for attacks, safety, and coordination. Pulling a pocket watch out of a pocket during combat was risky. Soldiers started strapping watches to their wrists, sometimes in leather pouches, giving birth to the wristwatch in its early form. Early wristwatches were still fully mechanical and hand-wound.
Why the Left Hand?
Most soldiers used their right hand for handling weapons. Wearing a watch on the right hand would make it prone to knocks, shocks, scratches, and damage. The delicate mechanical movements inside could easily be affected.
The left hand, being less used for heavy tasks, protected the watch from damage, increasing its lifespan.
Thus, the combination of crown placement, right-hand dominance, and the delicate nature of mechanical watches led to the practice of wearing watches on the left wrist. Over time, this practical habit became a social norm.
By the 1900s, watch manufacturers began designing straps, buttons, and ergonomics with the left wrist in mind, making left-hand placement the default for most wristwatches.
Is it necessary to wear it on the left?
Modern watches are much more durable. Most are automatic or battery-powered, eliminating the need for daily winding. Shock-resistant watches have significantly reduced the risk of damage from everyday knocks.
Technically, a watch can be worn on either wrist. Left-handed individuals often wear watches on their right wrist for convenience. However, most people worldwide still wear watches on the left wrist because it’s a long-standing tradition rooted in history, design, and social habits.
Wearing a watch on the left hand is not a coincidence. Its origins go back centuries to mechanical watch engineering, crown placement, and practical use of the right hand. What started as a convenience and safety measure has become a global tradition.
Even in today’s age of advanced technology, the wristwatch on our left hand remains a silent witness to that long history.
