The combination of yellow and black works great on a Grand Prix racing strap like this. Apart from the contrast stitching, the iconic large holes on the strap shine through showing tinge of the contrast colors from the padding used in the strap. By choosing the right contrast color to match the dial or bezel of your watch, you can be sure that your watch will be jazzed up without looking over the top. Our rally strap has 4 large holes on both sides of the strap which are not just design elements but also utilitarian. These holes provide breath ability which F1 drivers need as it can be extremely hot in their vehicle. We wanted to stay true to the roots by keeping the original design concepts of vintage racing straps. As a cherry on top, we have also included a deployant buckle to complete the look.
