This Franck Muller Jump Hour, reference number 7500 SC, is a gently pre-owned luxury watch that is also very rare. Photos of the actual timepiece show that it is in good condition, with no major signs of wear on the case, bezel, or back plate, though there is a scratch on the crystal, and the strap is quite worn. It is fully functional, and guaranteed 100% authentic. The 18k-yellow-gold case and bezel contain a guilloche-cream dial that tells time in a fairly unique way: It has a hand to indicate the minute, pointing to the red markers that range from 5 to 60; while the hour is displayed in the window at the top of the dial. A quartz movement powers it all. The black, leather strap will fit a wrist up to 8 inches, and uses a yellow-gold tang clasp. The case measures 28mm wide without the crown, and 38mm long with the lugs. The total weight of the watch is 1.8g.

However, they innovators at Franck Muller have accomplished combining the complications into a size manageable for anyone. Read More:
