This is for a compatible bar that is used for the newer style Omega Planet Ocean links on the 45.5mm and 46mm watches that have screws in the side. If you have lost the bar that sits between the two screws in your links this is an ideal replacement. Please make sure the link nearest your clasp is 20mm wide before you order this.
