New: DUO

Global premiere  - the first ever world timer based on the one-hand principle.

Our world may be growing together, but one border remains – time.

The DUO allows this border to be easily overcome. A dual one-hand watch, it shows both the local time and the time at one additional time zone, using just one hand in each case.

This is the simple yet amazingly logical principle which the DUO uses to give its wearer reassurance when dealing with different time zones.

The outlying main display shows the local time. Its striking 12-hour hand points to the same one-hand scale that has been used in the UNO for more than 25 years. The scale itself is mounted on a slightly inclined scale ring which guides the markings down to the lower-level 24-hour display.

The secondary display, which lies at a lower level in the dial, can show any second time zone the wearer chooses. Its delicate 24-hour hand and numbered scale are clearly distinct from the 12-hour main display.

What is more, an artificial horizon divides the inner 24-hour section into a day half and a night half, allowing the day half of the second time zone to be identified at a glance.

The DUO is a dual one-hand watch for anyone who is at home in two worlds.
