Aquis Dat Watt

The Oris Aquis Dat Watt is a standout within the Aquis lineup, created in partnership with the Common Wadden Sea Secretariat to highlight the importance of tidal wetlands. Its unique dial, inspired by the tidal flats of the Wadden Sea, sets it apart visually and thematically—making it a compelling option for collectors who appreciate watches with a genuine conservation story behind them. The model’s limited-edition status further enhances its appeal, as Oris produced only a set number of pieces for this special collaboration.

This 43.5mm diver features the Oris automatic caliber, offering reliable Swiss performance and a 300-meter water resistance rating, suitable for both everyday wear and aquatic pursuits. The most distinctive feature is the tidal complication at 12 o’clock, which tracks the lunar cycle and corresponding tides—a function rarely found at this price point. Reference numbers for the Dat Watt edition typically begin with 01 761 7765, denoting the movement and special dial, so check for this when comparing listings.

Prices can vary depending on condition, completeness (box, papers, original strap), and whether the watch is from the first wave of releases. Expect a premium for unworn examples with full sets. The tidal complication and limited production drive long-term collectability, but ensure the unique tide bezel and dial are in excellent condition, as these parts are not easily sourced for replacement. This model is not commonly counterfeited, so focus on originality and overall presentation when evaluating a purchase.
