This is our answer to a 3mm fold over since we can not seem to get a 3mm fold over. So if your fold over is 3mm or even 3.8, this should work for you. This is made with our new wider ribbed connecting link. The fold over clasp is only 2.87mm wide but can sometimes vary by .13 of a millimetre. The colour of this is silver tone, aka antique silver, the colour of a nickel. This is antiqued. Some are more antiqued than others. (Antiqued means old looking, blackened, dull, and or aged). This will extend your watch or bracelet by approximately 13/16". If you purchase the wrong width fold over, please contact me. We have solutions.
