This is a rare Montblanc automatic watch winder with various rotation controls (clockwise, counter clockwise and variable). It is constructed of wood with a piano black finish. It is battery powered. The original batteries (still in wrapping) are in the box; however, since they are very old, I highly recommend that you buy new batteries. The unit has four hour winding intervals. It accommodates any wrist size. This is new in box. It still has sticker film wrapped around it. This would make a great gift! My price is firm.
