This function opens the new, empty window named floater. Case is stainless steel with screw on back that is marked Illinois. Very clean dial is silver with raised yellow gold numbers and markers.
Hands have luminous centers.
Date at 3. Case is stainless steel with all the proper Rolex markings on inside case back. There is some pitting around the case back where the back touches the case. Original dial has some age but still too good to refinish. New brown lizard strap.
