The Poseidon Limited Edition is a numbered run of 500 and comes packaged in a luxurious gift box set which includes a 2-tone stainless steel bracelet, a rubber strap, tools and extra screwbars to change the bands. The LE version features a more sophisticated self-charging kinetic auto-quartz movement that never needs a battery (replacing the 10-year lithium powered quartz movement of the standard models), an exhibition caseback revealing a black-plated charging rotor, and Reactor’s exclusive Never Dark® illumination system.
