With an open heart

This at first sight somewhat unusual name for a watch refers to the irregularly shaped window in the dial of the Hamilton Jazzmaster Open Heart Auto. Through it you can see the high-precision Swiss movement that is the heart of your Hamilton Jazzmaster Open Heart Auto. Just below the twelve o'clock mark, you have a clear view of the balance wheel, which, like your own heart, is in constant, regular motion. Unlike a skeletonised watch, however, the Hamilton Jazzmaster Open Heart Auto shows only part of its inner workings, so the whole process remains mysterious and stimulates the viewer's imagination.

A closer look is worthwhile

But when choosing your Hamilton Jazzmaster Open Heart Auto, don't let the inner workings of the watch get to you. The movement is the same for all models in the collection. But the colour of the dial and the materials used are not the only differences. You should also pay attention to the shape of the window and size of the watch. Two models have a flower-like pattern that makes the watch more delicate, but offers less insight into the movement. On the 40 mm models, the window is so large that the number 12 is cut through in the middle, underlining the mystery of the Hamilton Jazzmaster Open Heart Auto, but making it less legible. On the 42 mm models, the 12 is complete and therefore clearly legible. This also makes the watches look a little tamer. So take your time to choose the Hamilton Jazzmaster Open Heart Auto that suits you best.
