The launch of this new Astron GPS Solar caliber is celebrated in a limited edition whose defining characteristic is its dark mother-of-pearl dial. The use of a colored mother-of-pearl is a silent tribute to the power of the technology beneath. The GPS Solar module requires so little power that it obtains all the energy it needs from light absorbed through the dial, even though it is made of this natural material. The design was inspired by the idea of the earth at night, as it might be seen from a GPS satellite. The effect is at once startling and yet mysterious. The case and bracelet are made of titanium with a new super-hard black coating that is resistant to scratches and which will preserve the sleek beauty of the watch for as long as it is worn. Each watch in the Limited Edition has its own individual serial number on the case back. The watch is offered in a special presentation box. The Limited Edition comes with two bracelets; one in highly-polished titanium with black ceramic inserts and the other in leather. Limited to 3500 pieces.
