black FKM-rubber strap for Rolex Explorer II
The material:
We buy the leather used in the production ourselves and test the material through many different ways to make sure that they fulfill our desired standards. For example, we have tested a variety of waterproof types of leather and their friction using wet and dry surfaces, but also their absorption of moisture after 30, 60 and 90 minutes.
In our company for DLC and gold/platinum coating
we have the necessary means to test and compare the many different kinds of caoutchoucs on friction and their chemical properties. A variety of waterproof leathers were tested in water for 90 minutes for multiple times to test their absorption.
Properties
We have presented you several information on development, all the way to the watch strap and on our Loop-Fixing-System. Last but not least, we’d like to give you further information on the material properties.
Watches are NOT included.
Slight color deviations due to different monitor settings and lighting conditions during photography possible.

Rubber:
Our people from the R-Straps company only use one rubber mixture made up of FKM material. The NBR-rubbers, which can be found on the market, show too many disadvantages like attracting dust and fuzz. Additionally, there are chemical disadvantages, which we cannot accept.
Even among the FKM mixtures are clear differences. Especially the smoothness can be felt by the customer when wearing them around their wrist. It needs to be soft and flexible but mustn’t be extensible because of these properties.
Furthermore, its performance under certain temperatures, especially in the cold, are important, as it still needs to preserve its flexibility. We had a vast variety of FKM materials sent to us by producers to test the differences. Now we had to find a manufacturer who was willing and able to incorporate the FKM rubber material that we had chosen. Eventually we found a manufacturer in Switzerland. In the section “The way to the strap” more information on the individual steps can be found.
Since I have worn leather and rubber straps with my Rolex watches in the past, I am familiar with the general problems of wearing them.
Rubber material is always striving to be straight, meaning that it works against the rounding of the arm. By using loops this effect is dampened. However, the FKM rubber is relatively smooth, so I kept having the problem that the second loop slided over the side of the strap with the loops or to the buckle. This effect is only amplified by sleeves of pullovers or shirts.

Loop-Fixing-System
Our goal was it to set new standards in quality and design, so there had to be done something about the wearing comfort. The result is the latching of the second loop by two stoppers, which prevent any shifting and guarantee a high wearing comfort.
