Striking the perfect balance between tradition and innovation, the Jazzmaster Open Heart offers a glimpse of its precise Swiss automatic movement in action. Thanks to the use of high-quality materials and a wide range of dial and strap combinations, this collection showcases the Hamilton brand in all its glory.
The Hamilton Jazzmaster Open Heart Automatic H32705142 men’s watch is part of the Jazzmaster line, and thanks to its elegant design, it’s suitable for special social occasions as well as everyday wear. Thanks to the Open Heart feature, the model offers a view of the rotor through the dial.
The case of the Hamilton H32705142 is made of stainless steel, as is its bracelet. Inside the case, the Swiss-made H-10 mechanical movement (based on the ETA C07.611, which is based on the ETA 2824-2) with automatic winding operates reliably. It operates at a frequency of 21,600 vibrations per hour and features 25 jewels. The movement’s operation can be observed through the transparent case back and, to some extent, through the view of the balance wheel on the dial.
The elegant yet easy-to-read blue dial is protected by a sapphire crystal that is highly scratch-resistant. An anti-reflective coating ensures excellent readability even in bright sunlight.
This model is water-resistant to 50 meters (5 ATM), so it can handle basic contact with water, such as rain or a shower.
The original steel bracelet for this model is marked H6054251011.

The Hamilton brand was founded in Lancaster, Pennsylvania, originally to produce only pocket watches. Thanks to the accuracy of the Hamilton watch, the problem of frequent accidents in the early days of railroad transportation in the United States was solved. It was the superior quality and accuracy of the first Hamilton pocket watches, as well as the ability to innovate and act quickly while maintaining high standards, that first caught the attention of the US military as early as 1914. As an official supplier to the US armed forces during World War I, Hamilton equipped hundreds of soldiers with reliable watches. This led to a shift in production from pocket watches to more comfortable wristwatches, a change that has stuck.
Groundbreaking, practical and precise: Hamilton uses a unique combination of Swiss precision and American spirit to create distinctive, versatile watches for style-conscious lovers. Hamilton has a long history and has achieved numerous milestones, all of which have contributed to making Hamilton the strong and internationally recognized watch brand it is today.
Helveti.eu is an authorized dealer and specialist of the Hamilton brand.
