IN reinterpreting the classic Sigma50 button, industrial designer Christoph Behling – lead designer for Tag Heuer and Geberit – has refined the plates, adding a slight yet elegant curve.

He has incorporated glass to make it even lighter. Finally, a frameless plate which gives the appearance as though it’s floating off the wall.

However, one aspect has been left entirely up to you; the colour of the actuator plate. Why should he have all the fun?

Available in seven design colours – white, black, smoked reflective, pergamon, white glass with ornament pattern, dark brown and mint green – to choose from.
