JB300 Steel Bracelet

JB300 Steel Jubilee Bracelet

On the JB300, the Jubilee takes on a new density. Five-link construction, same architecture as the JB200—but here, two finishes coexist: brushed on the outer links, polished on the center line. Not a decorative choice. A functional logic: the brushed finish absorbs daily micro-scratches, while the polished finish catches the light and traces a clean line through the heart of the bracelet. Two functions, one single piece.

Brushed outside, polished center

316L stainless steel. Four outer links in a brushed finish—matte, grainy, designed to age without showing it. In the middle, a mirror-polished line: the bracelet’s visual signature, which follows the wrist and catches the light with every movement. On the JB300, which is denser than the JB200 due to the case build, this duality of finishes balances the weight—the instrument retains its character while gaining a more articulated look.

JBM-signed deployment clasp

Double-security deployment buckle, engraved with the JBM logo on the cover. Clear opening via side double-pushers, secure closure, precise adjustment. An instrument clasp, not a decorative one—designed to be opened with one hand, withstand saltwater, and last.
