This is a UNUSED New Old Stock very cool black rubber tire surrounding a MARVIN manual winding (cleaned and accurate) steel watch with skeleton case back. This is a perfect pocket watch or display piece. I don’t recommend clipping the leather band to a belt, in case it rips-as the leather is old and has been stored for many decades. The SWISS company Marvin has long been associated with the automotive scene-particulary auto racing. I have a few of these available. Just $150!
