Your Spirit Zulu Time was built for adventure - now it wears like it too...

The Steel Reef “On The Fly” extension link adds instant ±5mm adjustment to your OEM Longines bracelet—equivalent to adding or removing a half link, anytime, no tools required.

Simply swap out the final bracelet link (where your clasp connects) with our custom 316L stainless steel version. It’s designed to sit discreetly under the clasp and perfectly match the original finish and styling, so it blends in seamlessly—like it was always meant to be there.

Unlike bulky, universal hacks, this is a precision-engineered upgrade made specifically for Longines—because true innovation shouldn’t stop at the crown.

Pre-orders now open. Small batch production. Early access ensures priority shipping.
