The Aquatimer Chronograph Edition “Expedition Charles Darwin” Story

The choice of bronze for the case pays homage to the well-known ship, HMS Beagle, that carried Charles Darwin on his expedition to the Galapagos Islands. In those days, bronze – which is non-corrosive – was used for portholes, fittings and nautical instruments. Depending on the use to which it is put, bronze develops a patina in the course of time and darkens in colour, giving the Aquatimer Chronograph Edition “Expedition Charles Darwin” its own unmistakable character. The bronze tone recurs in the luminescent material on the hands, indices and quarter-hour scale on the internal rotating bezel. Equipped with the IWC-manufactured 89365 movement, rubber-coated push-buttons, the SafeDive system and water-resistance to 30 bar, this special edition is ideal for expeditions in this day and age both on land and underwater. The engraving on the back is an expressive portrait of Darwin, whose revolutionary theory of evolution changed our way of thinking for ever.

Charles Darwin Foundation

Charles Darwin Foundation

Coastal landscapes with black volcanic rock, scorched hillsides covered with cactuses and holy wood trees, mountain peaks shrouded in mist – the breathtaking landscape of the Galapagos Islands leaves visitors spellbound. The unique flora and fauna on the volcanic archipelago situated around 1,000 kilometres from the coast of Ecuador has developed over the past 4 million years. Many of the unique species known as “endemic”, such as giant tortoises, Darwin’s finches and marine iguanas are not found anywhere else on earth. However, human settlement, the introduction of foreign species and overfishing are posing a serious threat to this fragile ecosystem. The Charles Darwin Foundation, founded in 1959 under the auspices of UNESCO and the IUCN, is committed to the protection of the islands through its continuous research and educational work in collaboration with the Galapagos National Park Directorate and many other national and international institutions. IWC Schaffhausen has been a partner of the foundation since 2009, supporting the work of over 100 researchers, students and volunteers with a share of the proceeds from the sale of special edition Aquatimer watches.

Calibre Family 89000

The 89000-calibre family includes powerful chronograph movements with flyback function, which are used, for example, for the big digital date and month displays or for watches that display stopped hours and minutes on a subdial.
