The Avanti Four Self Programming vertical winder modules powered by 5-year Lithium batteries. The patented ROTORWIND system "rocks" the watch in an oscillating mode, once every ten minutes, 24/7. This gentle action replenishes the mainspring tension lost in the previous 10 minutes, assuring virtually constant mainspring torque. That is the optimum arrangement to insure the highest watch accuracy. Ball bearing construction throughout, coupled with the use of Swiss designed ironless core precision servomotors assures long life with no maintenance ever required.
The AVANTI 4 is a simple way to store and wind watches in a safe or closet.
Avanti Four Module is also available in a horizontal format.
