If you’re anything like us, your inner child can’t get enough of all things exploration, space and NASA, which is why the first Casio G-Shock DW5600 NASA Watch was so popular among our readers. Casio is back for a second G-Shock Watch collaboration with NASA, and this time, they’re celebrating the 40th anniversary of the first space shuttle launch in 1981. This timepiece is very similar to the first G-Shock DW5600 NASA Watch except this time around the primary case is blacked out, the digital display reveals the OV-102 space shuttle when the EL backlight is illuminated and the steel case back features a commemorative engraving of the space shuttle. The silicone band also includes an American flag printed on the loop and mission specific badges / labels on the band itself. Whether you’re a fan of G-Shock, NASA, space, exploration, the USA, or anything related, this is the watch you’re going to want on your wrist for the next few years.
