ET66 Calculator



One of Braun’s most iconic creations, this ET66 Calculator is a replica based on the original design.

First designed by Dietrich Lubs and Diter Rams in 1987, the calculator was revolutionary thanks to its ergonomic round buttons, slim size and protective slide cover. Displaying your sums via a built-in eight-digit LCD screen, this re-release looks exactly like the original calculator from the 1980s.

An icon of modern design, the calculator can be found in the permanent collection of the Museum of Modern Art in New York and is said to have largely inspired the interface of Apple’s calculator.
