Based on the iconic Oris Aquis watch for divers, the new design focuses on the course of the River Rhine, which runs close to the village of Holstein, where Oris has been based since 1904.

The case back is embossed with a map of the River Rhine, which runs 1,233 km through six countries from its source at the Lai da Tuma, or Tomasee, a lake 2,343 metres up in the Swiss Alps.

Its 43.5mm stainless steel case is water-resistant to 300 metres and it has a uni-directional rotating bezel with a grey tungsten insert with a 60-minute timer scale for safely measuring dive times.

The automatic movement provides standout complication, an inventive circular date indicator shown by a scale running from 1 to 31 around the centre of the dial. Inside it is a channel with a white indicator that aligns with the scale and makes a full tour of the dial once a month to show the date.

The watch also has a sweeping seconds hand with a lollipop filled with luminescent Super-LumiNova. This is a significant detail – to qualify for diver’s watch status, a watch must have a display that shows the running of the watch to indicate to the wearer that their dive timing is accurate.

The watch comes on either a stainless steel metal bracelet or a grey rubber strap, both of which have stainless steel folding clasps that can be extended to be worn over a wetsuit. To reflect the height above sea level of the Lai da Tuma, 2,343 pieces will be made.
