Oris, which has been making divers’ watches since the 1960s, and which has a stated mission to protect endangered marine species, has set out to combat the threat of the world’s declining shark population with the release of a new watch, the Oris Hammerhead Limited Edition.

The Oris Hammerhead Limited Edition, which is based on the second generation of Aquis looking to be launched in 2011, is limited to 2000 pieces. Its sales proceeds will raise funds for shark conservation projects by Pelagios Kakunja, a nonprofit organization dedicated to studying the migration path of marine predators, to support professional divers Jelum Delafosse (and ambassador). Its multi-piece stainless steel shell measures 45.5 mm in diameter, waterproof 500 meters. The screw is covered with a crown protector. One-way rotating borders have the same polish, black ceramic mosaic Aquis family of predecessors, white diver’s minute range. The color of the blue ocean is clearly central seconds and blue numerals minutes around the gray dial.

The movement is Oris Caliber 752, based on the Sellita SW 220-1. In addition to its timekeeping functions, via central hours, minutes, and seconds hands, this self-winding movement powers a day-date function, displayed on the dial at 3 o’clock. The applied indices and polished nickel hour and minute hands are treated with Super-LumiNova; the luminous material also appears on the round “lollipop” of the blue central seconds hand. Covering the dial is a domed sapphire crystal with interior nonreflective coating. The watch’s screwed, steel caseback is embossed with the image of a hammerhead shark and the limited edition number.

The Oris Hammerhead Limited Edition is available on either a stainless steel link bracelet or a black rubber strap. Available in June 2017, and priced at 2,550 Swiss francs (U.S. price TBD), it comes in a special presentation box whose interior lid is also emblazoned with an illustration of a hammerhead shark.
