Click here for a guide to wearing and cutting the strap. 

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. This strap is not only comfortable and durable, it is also truly waterproof and easy to maintain. Whether you're hitting the gym, or dressing up for a night out, this strap has you covered. 

Each purchase will include the following:

  • 1 set of CTS straps (2 long straps of maximum length)
  • 1 spare CTS strap (1 side)

      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!
