Pioneering a more relaxed pace of life
Klaus Botta came up with the display principle of the UNO wristwatch back in 1986. As later became apparent, he had thus developed the world’s first wristwatch to employ the one-hand principle. The UNO became a bestseller and was heaped with international design awards. Even though the UNO triggered a wave of copycat one-hand watches by other manufacturers, the UNO remains unique and, above all, the original.

One-hand watches make do with merely an hour hand. Even at first glance, this reduced approach to displaying the time gives an approximate idea of the time. If more accurate information is required, the precise scale and the hand which is especially tailored to it allow you to work out the time at least to the nearest five minutes – after a brief period of familiarization, you will be able to achieve even greater accuracy.

The real strength of this display principle, however, lies without doubt in everyday time-keeping and the ease with which the time of day is presented with such clarity. The unique presentation of the time of day makes time seem to pass more slowly. In our hectic and fast-paced world, this intentionally simple and clear form of time display relieves the feeling of urgency in our everyday lives, giving rise to a sense of serenity and calm. 

The narrow case border can accommodate a very large dial. Because the time scale is positioned right at the edge of the dial, maximum resolution is achieved, allowing the time to be displayed with a high level of precision. In conjunction with the filigree hand, the time can be read to an accuracy of just a few minutes. The strap lugs are positioned underneath the circular case, which makes the watch much more comfortable to wear.
