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.
