Like all Astron GPS Solar calibers, 8X42 offers the remarkable ability to adjust to local time, anywhere_ in the world, at the touch of a button and using just the power of light. With the addition of the big date window, the inclusion of a dual-time dial at the six o'clock position and new, slimmer hands, the new designs have a refinement that makes them as perfect for an evening out as they are for international travel. With several versions featuring roman numerals for the first time in any Astron design and with more components having mirror finished surfaces, the Astron dress watch has truly arrived.
