About
The calculator has quietly resisted obsolescence, even as every device in your pocket can divide numbers. What persists is the satisfaction of a dedicated tool, the tactile feedback of buttons designed specifically for calculation, the clarity of a display that doesn't compete for attention with notifications.
Braun's reissued calculator draws from the original ET66 design, created in 1987 by Dieter Rams and Dietrich Lubs during the height of the company's minimalist philosophy. This pocket calculator strips away everything except what calculation requires: an 8-digit LCD display, convex circular buttons arranged in logical rows, and a rectangular form that fits naturally in hand or desk drawer. The ABS plastic construction feels intentional rather than cheap, with a protective slide cover that keeps the display and buttons safe during transport.
The convex button design is where restraint becomes function. Each button sits slightly raised, its circular form offering natural tactile feedback without requiring you to look down while calculating. The automatic power-off after six minutes of inactivity means the included alkaline battery lasts months between replacements, a small courtesy that prevents the dead-battery moment. There's no backlit display or unnecessary features competing for space; the interface exists to solve one problem clearly.
For designers, architects, and anyone who still prefers pen and paper with a dedicated calculator nearby, this Braun calculator offers something the smartphone cannot: the focused simplicity of a tool that does one thing and does it without distraction. It sits on a desk like a small sculpture, a reminder that good design doesn't require reinvention, only honesty about what's needed.
