'Tact' from Julien Bergignat is an innovative watch designed to allow blind people to feel the time. Normal watches can be flipped up and felt, but doing this can cause the needles on the watch to skew in different directions and tell the wrong time in the future.
Tact from Julien Bergignat solves this problem by using raised dots to tell the time. One dot represents hours, while the other represents minutes. Tacts is also no slouch in the looks department with a silver finish and futuristic look. Tact looks great and helps the blind tell time.
