The Tachymetric Scale

A key part of the model’s identity is the bezel moulded with a tachymetric scale for measuring average speeds of up to 400 miles or kilometers per hour. Blending high technology with sleek aesthetics, the black bezel is reminiscent of the 1965 model fitted with a black Plexiglas bezel insert.

The monobloc Cerachrom bezel in high-tech ceramic offers several advantages: it is corrosion-resistant, virtually scratchproof, and the color is unaffected by UV rays. This extremely durable bezel also provides an exceptionally legible tachymetric scale, thanks to the deposition of a thin layer of platinum in the numerals and graduations via a PVD (Physical Vapour Deposition) process. The monobloc Cerachrom bezel is made in a single piece and holds the crystal firmly in place on the middle case, ensuring waterproofness.

White Dial

This model features a white dial with snailed counters, gold applique hour markers, and hands with a Chromalight display, a highly legible luminescent material. The central sweep seconds hand allows for an accurate reading of 1/8 second, while the two counters on the dial display the elapsed time in hours and minutes. Drivers can accurately map out their track times and tactics without fail.

Oystersteel

uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, which is commonly used in high-technology applications, including the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished, and maintains its beauty even in the harshest environments.

MODEL AVAILABILITY

All watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict RLX's production capacity, and at times, the demand for watches outpaces this capacity.
