RM 025 Diver's Watch Coupled with New Kalrez Strap

The Richard Mille RM 025 Diver’s watch, unveiled at the beginning of 2009, represents an extremely high-tech tourbillon chronograph watch that incorporates a carbon nanofiber baseplate and boasts 300-meter water-resistance.

Now, Richard Mille has equipped its bold timepiece with a new strap, made of perfluoroelastomer Kalrez. The material used for the strap is perfect for pharmaceutical industry, aerospace and aeraunautics fields that need a supreme degree of purity. Kalrez significantly reduces absorption, desorption and products of extraction, thus guaranteeing minimal contamination.

It is remarkable that the perfluoroelastomer Kalrez strap offers almost absolute chemical resistance. It maintains its properties at high temperatures up to 327 degrees Celsius.

Moreover, the strap’s composition offers outstanding watertight protection, implying longevity and insignificant residual deformation, so Kalrez pieces are resistant to the extreme pressures under deep-sea conditions.

The strap of the RM 025 Diver’s watch will also withstand pressures of everyday life. It should be mentioned by Watches.InfoNIAC.com that simple rubber straps are gradually damaged by heat, UV light, a variety of chemical agents and even pollution.

The Kalrez strap is produced by Biwi SA, a Swiss firm that deals with the moulding of high-precision vulcanized elastomers, including rubber and silicone. The list also includes technical plastics required for manufacturing watchmaking components and medical parts.

The creation of the Kalrez strap is based on a successful partnership between the producers of Kalrez, DuPont Performance Elastomers, and Biwi SA.

The RM 025 Diver’s watch incorporates a rotating bezel and micro-injection moulded pushers, produced from a patented Vulcamix process of injection and finishing that allows a finely crafted, pleasant-to-the-touch mechanism. Biwi SA received the patent for this technique.
