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 H32675140 is part of the Jazzmaster range and its elegant design makes it suitable for special occasion company, but feel free to wear it everyday. Thanks to the Open Heart, the model provides a see-through dial on the flywheel. The case of the Hamilton H32675140 is made of stainless steel, as is its bracelet. Inside the case, the Swiss mechanical movement H-10 (based 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 features 25 jewels and, most importantly, an extended power reserve of 80 hours. The movement's operation can be observed through a transparent dial and partly through the inertia window in the dial. The flywheel of this movement is made of Nivachron alloy, which is more resistant to magnetic fields and temperature changes and has the effect of improving the accuracy of the watch. The elegant yet clear blue dial is protected by a sapphire crystal that is maximally 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.
