These come in several different strengths and the ones I can currently supply are shown in the drop-down list. Also, I likely have several in each strength of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
