Introducing another new peak in comfort and style: our FKM Rubber Cut-To-Size ("CTS") rubber watch strap. Customisable to fit your wrist perfectly and secured with a sleek leaf-spring deployant clasp, it is also available in a range of colours to suit your personal style.

      Amazing quality for a rubber strap

      Most rubber straps I've gotten feel cheap. This one feels premium and the CTS clasp is a way better experience than a normal buckle.

      Best Strap I’ve ever purchased!

      After spending hundreds of dollars trying to find the perfect strap for my Longines Spirit Zulu Time, I decided to take a chance on the Delugs CTS rubber strap that popped up on my Instagram. I’m SOOO happy I did!!!! This is the best CTS Strap I’ve had (and I’ve tried multiple, even from Longines). It’s SUPER EASY to size and the clasp is amazing!!! I love the minimalist, sleek look of it and how the clasp is not bulging off my wrist!!! Best purchase of a watch strap I’ve made!
