In 1976, the first pocket calculator, the ET 33 (2), was launched; to this day,
it is regarded as a particularly successful product in terms of ergonomics and design. Its convex buttons were a world first. The design of the successor device, the ET 44 (3), inspired Apple 30 years later when it was developing the iPhone. Nowadays,
clocks and alarm clocks are licensed products, and are being relaunched with new designs.
