Our Leather, Alligator, Canvas, Sailcloth, and Elite Silicone watch straps are available in 19mm widths as well as five different buckle colors. Be sure to select the proper width and color before adding to cart. For all of our NATO Style straps, we recommend using a 20mm width to accommodate watches with lug widths of 19mm.  The 20mm NATO-style straps will typically squeeze into a 19mm lug quite nicely.
