black abrassion-resistant goat leather strap for Rolex Oyster Perpetual
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.

Tannery Haas, the special tannery:
We purchase our Novonappa leather directly from the tannery Haas.
This leather became famous under the name of Barenia, which was then trademarked by the company Hermes. It’s a very fine calfskin leather. Originally Novonappa leather, in other words Barenia leather, has been used for the productions of saddles. The leather is tanned twice, once chemically and once vegetable tanned. The production procedure takes about 6 weeks. During this time the leather is treated with 9 different kinds of oil. Because of this elaborate process the leather obtains a very good quality and durability. For instance, its water tolerance is very good. Its design shows a deep brilliance.
Likewise, the enthusiasts of Novoappa leather treasure another property immensely:
The patina
Because of external factors the leather develops a unique patina, which gives each band a unique appearance, since it doesn’t use an aniline finish. Further information can be found in the documents which have been kindly provided by the Haas company.
The way to the watch strap Leather and FKM rubber:
Our watch straps are nestled tightly with ABS system in their housing. This part of the strap has the same purpose as the end piece of the Rolex watch straps – a seamless and smooth transition between watch strap and housing.
To put this system into practice the different watch housings have to be measured. Using the data as a basis, first instruments for the productions are being produced and fitted into the housing.
Now the precision work begins, which means that the testing pieces for the rudiment of the different leather types and FKM rubbers are adjusted individually. In this case an original housing is essential. Nevertheless, it is vital to control the watch straps regularly. It needs to be added that during the production of our watch straps there are still people operating the machines, doing the first quality check after the product’s completion. Afterwards each strap is tested using a pressure process working on the housing. For the medium heightening of the leather straps a second tool is needed.
The design:
The company R-Straps is, as far as our knowledge goes, the first company to use the same consistent design for their whole range of products, irrespective to the material, to achieve a consistent picture. This medium heightening has also been incorporated by us to give the watch strap a consistent design. All threads, which have been incorporated into our straps were produced by the Ammann company.
