The Seiko Think the Earth WN-1 has to be one of the most unusual timepieces you are likely to see. Commissioned by Think the Earth Project, an organisation to promote Earth awareness and provide aid and assistance to vulnerable children. Designed and engineered by Seiko Instruments Inc. The 45mm case is made of Titanium, it has a 24-hour etched Titanium bezel. Domed Hardlex protects the 3D globe of the Nothern hemisphere, which rotates anti-clockwise mimicking the Earths axis completing its full rotation in 24 hours. A white marker indicates the hours and rotates anti-clockwise with the Earth, the minute orange dot rotates clock-wise as an ordinary watch. Time can be best seen from a top-down position. Powering the watch is a specially designed precision Seiko quartz movement, with 3 reducing gears in the drive train necessary for the unique rotation of the globe and hands. Having a screw-down case back gives the watch 100m water resistance.
