Description Technical Specs
 
The sloped front case houses an easily removable drive station fitted with three ironless core gear motors to provide independent operation for each of the three rotating cups.  Case is fitted with a beveled glass viewing panel.
Unlike other watchwinders which rotate a watch in order to wind it, the unique SPARTA watchwinder gently swings the watch instead.  Every 8 or 12 (extended program) minutes the internal control micro-processor signals the drive motor to make a single turn, causing the watch to swing back and forth for several oscillations just as it would if it were being worn on the wrist.
The Siena 3 Watchwinder is powered by two pair of "D" cell lithium batteries.  As the drive motor only powers the first oscillation of each winding cycle, with all succeeding oscillations totally powered by gravity, battery drain on the motor is minimal.  Hence, the Siena Watchwinder is guaranteed to operate for an average of four to five years without any need for a battery change.
