Perfectly balancing tradition and innovation, the Jazzmaster Open Heart offers a glimpse of its precision Swiss automatic movement in action. With the use of quality materials and a range of dial and strap combinations, this is a collection that shows the Hamilton brand at its best. The Hamilton Men's Jazzmaster Open Heart Auto H32705141 is part of the Jazzmaster range and its elegant design makes it suitable for a special occasion in company, but at ease for everyday wear. Thanks to the Open Heart, the model provides a see-through dial on the flywheel. The case of the Hamilton H32705141 is made of stainless steel, as is its bracelet. Inside the case, the Swiss mechanical movement H-10 (built on ETA C07.611 built on ETA 2824-2) with automatic winding works reliably. It operates at a frequency of 21,600 semi-frequencies per hour and has 25 jewels. The operation of the movement can be observed through the transparent dial and also partially through the inertia sight in the dial.The elegant yet clear blue dial is protected by a sapphire crystal, which is extremely scratch-resistant. The anti-reflective coating guarantees excellent legibility even in the harsh sunlight. The water resistance of this model is 50m (5 ATM), so it can handle basic contact with water, such as rain or a shower.
