Hamilton Jazzmaster Open Heart Auto

40 mm, Stainless Steel, 2824-2 Caliber The design of the new Hamilton Jazzmaster Open Heart turns timekeeping into something of a tease. A glance at the face of the watch reveals part of the Swiss automatic movement in action – but not all of it. Some things can be left to the imagination – especially when they are clothed in sumptuous quality materials and fine design detail.
