This Braun BNE001BK calculator is a replica of the Braun ET66 calculator, one of Braun's most iconic designs. The classic was designed in collaboration by Dietrich Lubs and Dieter Rams and originally released in 1987.
The Braun ET66 calculator is considered to be the pinnacle of the "less but better" philosophy thanks to its simple, rectangular design with convex, circular buttons. The Braun BNE001BK includes the philosophy of the classic and modernises it: The design with the round buttons and the whole exterior shape remain the same, while the display now operates with modern LCD technology. Besides basic arithmetic operations, the BNE001BK is also capable to calculate percentage.
