Meet the Great Barrier Reef Limited Edition IV, a 2,000-piece limited-edition based on the Aquis Date and inspired by the pioneering work of Reef Restoration Foundation. Behind its beautiful gradient blue dial is our Calibre 400 five-day automatic.

We are launching the fourth watch of our Great Barrier Reef Limited Edition series as a part of our long-standing commitment to the Australian Great Barrier Reef, the world’s largest reef system.

Inside the Great Barrier Reef Limited Edition IV’s 43.50 mm stainless steel case is our Calibre 400, a high-performance five-day automatic with elevated levels of anti-magnetism, a 10-year warranty and 10-year recommended service intervals.

Reef Restoration Foundation is an Australian non-profit working to combat the devastating effects of coral bleaching on the world’s coral reefs. Healthy reefs are vital to our planet’s health and it’s a privilege to support the foundation’s work.
