24 hour watches have a different gearing, with a 24 to 1 reduction. To be very technical, the motion work is the small 12-to-1 (or here a 24-to-1) reduction gear train that turns the timepiece's hour hand from the minute hand. It is attached to the going train by the friction coupling of the cannon pinion, so the minute and hour hands can be turned independently to set the timepiece. It is often located on the outside of the movement's front plate, just under the dial.The watch comes with CERTIFICATE OF AUTHENTICITY. NOTE:PLEASE OBSERVE CAREFULLY THE PHOTOS! IT IS A SIGNIFICANT PART OF THE DESCRIPTION. Every potencial defect which is shown in the photos, but not mention in the description, will be considered for described. All the photos shoot by professional Nikon 105 Macro lens under 40x diopter magnification, so you can explore even the smallest detail like under microscope!
