As the name implies, INSAFE winders were primarily designed for the watch collector who keeps his/her watches stored in a safe or vault. These units are totally "wireless", operating with four supplied Lithium "D" cell batteries.
In addition to a master switch each winding 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. These winders are normally free standing but also can be easily built into walls or in closets. The pedestal base is removable. This is the open front version.
