Hamilton has created watches that combine functionality with excellent design. They are also well-known for their affordable prices, making them a great choice not only for those new to luxury watches, but also as a second or third watch for enthusiasts. Let's take a look at Hamilton's history, classic collections, and recommended models.

Jazzmaster Open Heart


Hamilton, an American watch brand

Hamilton

Hamilton was founded in Lancaster, Pennsylvania, USA in 1892. Its history began with the manufacture of pocket watches, and has gone on to produce numerous masterpieces.

Switzerland is the first country that comes to mind when thinking of the mecca of luxury watches, with a long list of prestigious brands boasting history and tradition.

However, Hamilton is a brand founded in the United States in 1892. As a rare brand that combines the American spirit with traditional Swiss manufacturing techniques, it has long been loved by watch enthusiasts.

Developed as a railway clock

POCKET WATCH 992

The railroad watch "POCKET WATCH 992" was manufactured in 1920. It is no exaggeration to say that the railroad accidents in America at that time were solved by Hamilton's high-precision timekeeping.

Hamilton's history is closely linked to the emergence of the steam locomotive.

In the 1830s, the United States saw a rapid development of its transportation network, triggered by the introduction of steam locomotives. However, at the same time, railroad accidents caused by clock errors also increased.

Of course, quartz watches did not exist in this era. Timekeeping was entirely done by mechanical watches. While mechanical watches are now highly accurate, the reality is that mechanical watches at the time still lacked reliability.

Hamilton attracted attention for its high-quality watchmaking technology in the turbulent railroad industry. In 1912, Hamilton's highly accurate pocket watches earned the title of "The Watch of Railroad Accuracy."

Hamilton's high-precision timepieces enabled precise timekeeping on the railroads, and the brand became known around the world. Hamilton watches were later adopted by industries other than railroads, and in 1918 they were even used by the United States Air Mail Service from Washington, DC to New York.

Hamilton watches are known for their accuracy and reliability, and were extremely popular not only with railway companies but also with pilots.

Demand for military watches

Military Watch - Grade II

Hamilton produced "Military Watches - Grade II." Grade II refers to the accuracy requirements set by the US military.

Hamilton began supplying the U.S. Army in 1914. Around this time, the company began to shift from producing pocket watches to wristwatches.

In the 1920s, numerous military watches were produced, including those for military operations, and they became widely used by soldiers in the U.S. Navy and Air Force.

マリンクロノメーター

Hamilton's marine chronometers were supplied to the US Navy.

In 1942, during World War II, the company stopped producing watches for the general public and began supplying huge quantities to the US military.

The history of Hamilton watches as military watches is proof that they were functional enough to meet the needs of the military.

'E'Award

During World War II, Hamilton supplied over one million wristwatches and marine chronometers to the U.S. military, and in recognition of this achievement, the company received the U.S. Army and Navy's 'E' Award five times between 1943 and 1945, an award given exclusively to outstanding suppliers of military supplies.

The birth of the Hamilton Pulsar, a watch that changed the history of watches

Hamilton Pulsar Time Computer

The Hamilton Pulsar Time Computer was announced on May 6, 1970, as the world's first LED digital watch. By pressing a button on the side of the watch, the time would be displayed in red LED numbers on the screen, and by holding down the button, the seconds would be displayed, completely changing the way time was displayed.

Hamilton, which had made a name for itself as a manufacturer of military watches, released the Hamilton Pulsar Time Computer in 1970, a pioneering digital watch.

This watch was highly praised as a "computer on the wrist" and overturned conventional wisdom in the watch industry. Digital watches are commonplace today, but Hamilton was the first to create them.

Hamilton's appeal lies not only in its traditional watchmaking techniques, but also in its excellent development capabilities in advanced fields.


Hamilton's iconic collection and history

Hamilton's three most representative collections today are the Jazzmaster, Ventura, and Khaki Field.

Both models are not only excellent in specs but also in cost performance, and are gaining support, especially from young businessmen.

"Jazzmaster" inherits the spirit of jazz

The Jazzmaster is a popular collection from Hamilton that recreates the world of jazz. It features a watch style that is faithful to the basics and a beautifully curved round form.

There is a wide variety of options available, like an improvised jazz performance, so you can enjoy choosing a watch that matches your fashion.

The main lineup of the Jazzmaster includes the beloved Open Heart, the sporty chic new Performer, and the Viewmatic Auto, with its beautiful, timeless and simple design.

"Ventura" has strong ties to the film industry

Elvis Presley

The Ventura was worn by Elvis Presley, the main character, in the musical comedy film Blue Hawaii. Elvis continued to wear the Ventura both in public and private.

The Ventura was originally created as a battery-powered watch rather than a mechanical one, and is a unique collection with its original asymmetrical form.

The Ventura became a signature Hamilton collection after being worn in the 1961 film Blue Hawaii.

Hamilton was a pioneer of battery-powered watches and is highly regarded within the watch industry as a model that brought innovation to the industry. Although it was sold at a high price of about six times the starting salary of a college graduate at the time, it became a huge hit due to its high convenience.

The design of the Ventura was created by renowned American industrial designer Richard Arbib, who created the unique style of the Ventura.

Believing that the entire watch should be a complete design, he created an innovative watch design that integrated everything from the dial to the bracelet.

Khaki Field, with its roots in army watches

The Khaki Field is a military-inspired model that is a modern reinterpretation of the "hack watches" issued to the U.S. Army. It combines high visibility with practical specifications, making it a "real military watch."

The Khaki Field is available in a wide variety of dials and straps. The highly customizable NATO strap, combined with its toughness, is popular with a wide range of age groups.

Among Hamilton's aviation watches, the Khaki Pilot, released in 2023, has a compact exterior with a 36mm diameter case and a thickness of 11.15mm. The outer edge of the dial is cone-shaped, and together with the Arabic numeral indexes on the dial, which vary in size, create a three-dimensional effect on the entire watch.

In addition, the indexes and hands are coated with X1-grade Swiss-made Super-LumiNova®, making them highly readable not only in bright places but also in dark places.
