The design of the 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.
A three-hand movement with a date function and boasting a superior power reserve of 80 hours, the H-10 appears with intricate contrasting snail and pearled patterns for the American Classic models it drives and streamlined surfaces for the pilots’ watches.
