As with the INSAFE 4-head version, the SPARTA 6 INSAFE winder was primarily designed for the watch collector who keeps his or her valuable watches safely stored in a safe or vault.
These units are totally portable and wireless, operating for years and years with the 4 supplied Lithium "D" cell batteries. Clearly, with battery life measured in terms of years, not months, there is no need for providing AC power. Two master switches are provided, each controlling three winding heads, In addition, each head is individually powered with its own on/off switch and operating mode switch. The rugged wooden case is covered with durable black vinyl material.
