With a diameter of 39mm in an extra-flat (6.8mm) and ultra-light (55g) version, the BRS Ceramic is a more urban interpretation of the BR 01 Professional Instrument (46mm). A size that is suitable for everyday use, an ergonomic case with a remarkably flat profile, in accordance with the four fundamental Bell & Ross principles: readability, functionality, accuracy and water-resistance. The guaranteed-reliable BRS Ceramic has a quartz movement. The unscratchable, high-tech ceramic combines both light weight and strength. It weighs a featherweight 55g. The immaculate black colour throughout its volume is fade-resistant.
