We've trimmed the fat off our Supreme Militex and made it even smoother, slimmer and comfortable! We've added G-Force buckles which are thicker, durable and more scratch resistant. Our competitors use thin and flimsy buckles which will scratch and bend over time. Our Ultra Militex is the best in it's class. With it's beautiful metallic sheen, this strap speaks quality throughout. Designed with the most meticulous watch aficionado in mind. Good to know: These will cover heart rate sensors on smart watches. See our smartwatch compatible version here.
