The must-have Macro Loupe for all watch lovers

I fell in love with the Jazzmaster Open Heart watch, which focuses on precision with a new 42mm dial. Featuring a captivating shimmering midnight blue dial, this fascinating watch combines the modernity of urban architecture with the infinity of the cosmos. Highlighting Hamilton’s craftsmanship and attention to detail, the dial reveals the H-10 automatic movement. With its 80-hour power reserve and Nivachron™ balance spring, the Jazzmaster Open Heart Auto is mounted on a refined blue leather strap.

<p dir="ltr">The <strong>Hamilton</strong> brand is an icon in the world of watchmaking which brilliantly combines American know-how and the finesse of Swiss watchmaking tradition. Founded in <strong>1892</strong> by Webster Clay Ball in Lancaster, Pennsylvania, the brand Hamilton quickly acquired a reputation for quality, precision and reliability, notably thanks to its pocket watches used by railway workers to avoid accidents on American railways.</p>
<h2 dir="ltr">History of the Hamilton brand</h2>
<p dir="ltr">However, it was truly from the 1950s that the brand began to make its mark on the history of modern watchmaking. In 1957, Hamilton revolutionized the world of watchmaking by introducing the world's first electric watch, the Hamilton Electric 500. This watch, although imperfect, paved the way for a new era of electric and quartz watches, in which will engulf<a href="https://www.dialicious.com/en/lip"> LIP</a> with the<a href="https://www.dialicious.com/en/lip/electronic"> LIP Electronic</a>,<a href="https://www.dialicious.com/en/bulova"> Bulova</a> with the<a href="https://www.dialicious.com/en/bulova/accutron"> Bulova Accutron</a> and of course<a href="https://www.dialicious.com/en/seiko"> Seiko</a> with the<a href="https://www.dialicious.com/en/seiko/quartz"> Seiko Quartz</a>.</p>
<p dir="ltr">The 1960s marked another pivotal moment for Hamilton. The brand entered the world of cinema by equipping Elvis Presley with a Hamilton Ventura in the film &ldquo;Loving You&rdquo; in particular. Hamilton thus extended its influence to the entertainment industry, becoming the watch of choice for many movie characters.</p>
<p dir="ltr">In 1974, Hamilton was in serious financial difficulties and was bought by the Swiss holding company SSIH, the ancestor with ASUAG of the current Swatch Group. This acquisition marks the beginning of a new era for Hamilton, which now combines bold American design with Swiss watchmaking excellence.</p>
<p dir="ltr">These key dates in Hamilton's history reveal a resolutely avant-garde brand, always seeking innovation and precision. Hamilton has been able to adapt to technological and cultural developments, while preserving its unique identity.</p>
<h2 dir="ltr">What are the iconic models of the Hamilton brand?</h2>
<p dir="ltr">Hamilton's rich heritage is reflected in the diversity of its collections, which meet the needs of watch enthusiasts from all walks of life. Among the brand's flagship models, we find:</p>
<h3 dir="ltr"><a href="https://www.dialicious.com/en/hamilton/ventura">Hamilton Ventura</a></h3>
<p dir="ltr">The Hamilton Ventura is probably the brand's most iconic model. With its bold shield-shaped case designed by American designer Richard Arbib (also behind the Hamilton Pacer and Hamilton Meteor models in particular), its water resistance up to 50 meters, its comfortable leather strap, its movement precise quartz, its elegant silver dial and its date complication, <strong>the Ventura is a symbol of innovation and aesthetics</strong>. It was this watch that Elvis Presley wore for the first time in 1961 in the film &ldquo;Blue Hawaii&rdquo;, which contributed to his legendary aura.</p>
<h3 dir="ltr">Hamilton Khaki Navy Frogman</h3>
<p dir="ltr">The <strong>Hamilton Khaki Navy Frogman is a robust and reliable dive watch</strong>. Featuring a 42mm titanium case, impressive water resistance up to 100 ATM, durable rubber strap, H-10 automatic movement with 80 hour power reserve, a black dial with luminous indexes and a date complication, this watch is designed to withstand the most extreme conditions. It takes its name from the 1951 film "The Frogmen", in which US Navy divers were equipped with Hamilton watches. An additional illustration of the close ties maintained by Hamilton with the film industry and in particular the Hollywood studios.</p>
<h3 dir="ltr">Hamilton Jazzmaster Viewmatic</h3>
<p dir="ltr">The <strong>Hamilton Jazzmaster Viewmatic is a classic and refined watch</strong>. It features a 40mm stainless steel case, water resistance up to 5 ATM, stylish leather strap, Swiss automatic movement, silver dial with applied indexes and date complication. Its particularity lies in its transparent background which allows you to admire the movement.&nbsp;</p>
<h3 dir="ltr"><a href="https://www.dialicious.com/en/hamilton/khaki_field">Hamilton Khaki Field</a></h3>
<p dir="ltr">The <strong>Hamilton Khaki Field is the symbol of the brand's military past</strong>. Equipped with a 38mm stainless steel case, water resistance up to 5 ATM, sturdy canvas strap, H-10 automatic movement with 80 hour power reserve, matte black dial with luminous indexes and a date complication, this watch is a tribute to the soldiers' watches used during World War II.

One of its flagship representatives, the Khaki Navy Scuba, features a 40 mm stainless steel case, water resistance up to 10 ATM, a steel bracelet, an automatic movement, a blue dial evoking the depths of the ocean with luminous indexes, and a date complication.</p>
<h3 dir="ltr">Hamilton Khaki Aviation</h3>
<p dir="ltr">The Hamilton Khaki Aviation is designed for aviation enthusiasts.

<h3 dir="ltr"><a href="https://www.dialicious.com/en/hamilton/psr">Hamilton PSR</a></h3>
<p dir="ltr">The Hamilton PSR is a modern reinterpretation of the first digital LED watch, the<a href="https://www.dialicious.com/en/pulsar/p2"> Pulsar P2</a> from 1970, popularized for being the watch of James Bond and Roger Moore in Live and Let Die in 1974. The PSR features a 40.8 x 34.7 mm stainless steel case, water resistance up to 10 ATM, a steel bracelet, a unique hybrid quartz movement with an OLED display and LCD technology, and a dial that lights up at the press of a button.</p>
<h3 dir="ltr">Hamilton American Classic</h3>
<p dir="ltr">Finally, the American Classic is a collection that pays homage to Hamilton's American history. The Intra-Matic Auto model, for example, offers a 40 mm stainless steel case, water resistance up to 5 ATM, a brown leather strap, an H-10 automatic movement, a silver dial in a style Vintage with stick indexes and a date complication.</p>
<p dir="ltr">These watches embody the spirit of Hamilton: a combination of functionality, design, history and innovation in a price range between &euro; 700 and &euro; 2,500 for a mechanical model.</p>
<h2 dir="ltr">How much does a Hamilton watch cost?</h2>
<p dir="ltr">Hamilton offers several dozen new references whose prices vary between $375 for a Hamilton Khaki-Field Quartz and $12,000 for a Hamliton Ventura Quartz in 18k gold. <strong>Most Hamilton are sold between $500 and $1,000</strong>. Prices can also fluctuate depending on the distributor, and promotions sometimes allow you to benefit from a more competitive price.

<p dir="ltr">(Updated December 2023)</p>

In my possession for over 10 years, I still enjoy wearing this Jazzmaster with its partially openwork dial. The only brown watch in my collection, I love the sunburst and the way the light highlights each element of the dial. A watch that I wear regularly and that I appreciate for its precision, not one revision and it is still as precise!

A very nice daily

Having owned this watch for over 10 years, I can only emphasize the robustness of this piece. No problems to report, no breakdowns. Movement rather correct in terms of precision for this price range (ETA movement). 
Its rather thin case and an ideal size of 40mm make it very pleasant to wear on a daily basis. 
The open heart adds a real touch of originality and brings this beautiful timepiece to life. 
This is my first mechanical watch, so I have a pleasant memory of this first purchase which opened the doors to my passion for watchmaking.

A first step in mechanical watchmaking!
