#311 of 2009 pieces. Based on the Oris Aquis diver’s watch, the Dat Watt Limited Edition is named after a local dialect for the Wadden Sea. The 2,009 pieces mark the year the Wadden Sea was awarded UNESCO World Heritage Site status.
The Dat Watt Limited Edition is a special watch. Its dial displays the lunar cycle and tidal range in the Northern Hemisphere via the Oris-developed Pointer Moon function, created for professional divers. This works using a central white pointer hand that once aligned with the correct day in the 29.5-day lunar cycle, shows the corresponding tidal range via the white outline on the dial. The same hand indicates the waxing and waning of the moon.
