Now available in a 42mm case. The design of the Jazzmaster Open Aperture turns timekeeping into something of a tease. A glance at the blue dial 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 sapphire crystal tops the stainless steel case, which pairs elegantly with the stainless steel bracelet for a seamless look.
