Rubber flat design watch band with stainless steel buckle. - Material: Rubber - Buckle Material: Stainless Steel - Design: Flat design Thank you for viewing. This is an old item from over 20 years ago, probably one of a kind. The rubber is in good condition, and changing the Seamaster's strap to this will make it look very sophisticated and different. The strap width is 19mm. I don't think you'll see this again, so if you're interested, please get it. The rubber color is navy.
