In short: the Carbon FKM strap (€449) is our most technical strap for the Royal Pop 40mm. It is made of FKM, a fluoroelastomer that stays flexible and resists heat, sweat, UV and most oils and chemicals. It comes in 12 colours, adjusts without tools and swaps in about 30 seconds.
What is FKM?
FKM is a family of fluoroelastomers, technical rubbers known for their resistance to heat, oils and chemicals. In watchmaking, FKM straps are valued because they feel dense and soft, keep their shape and are easy to clean. They are a step above standard silicone in feel and durability.

If you mainly want a light, colourful everyday strap, silicone is the better value. If you want the most premium soft strap, FKM is the choice. More in our sport bracelet guide.

Who is it for?
- Active owners who wear their Royal Pop for sport, travel or outdoor days.

Care
Rinse with lukewarm water and mild soap after sport or the sea, then dry with a cloth. FKM is easy to clean and does not absorb odours easily. Our care guide has more tips.
