25mm JB Champion Gold Expansion Band – Mid-Century Wave Style – Mild Wear

This is a vintage JB Champion 10K gold-filled and stainless steel expansion watch band, likely produced in the late 1940s. It features a rare 1-inch (25mm) width and a sculpted wave-link design that blends mid-century elegance with bold visual appeal. The inner clasp bears JB Champion’s distinctive triangle hallmark, confirming its origin from one of America’s premier watch band manufacturers. The band is in excellent vintage condition, with mild surface scuffing consistent with age. The gold-tone finish remains vibrant, and the expandable design offers a comfortable, flexible fit without the need for sizing or adjustment.
