Going to the ends of the Earth is nothing new to Eric Larsen. As a polar adventurer, expedition guide and educator, he’s spent the past 20 years traveling in some of the most remote and extreme environments on the planet. To date, he has completed more North and South Pole expeditions than any other American in history.

Sharing a concern for man's impact on the environment, Citizen sponsored Eric Larsen's Last Degree North Pole Expedition in April 2018, as well as his LAST SOUTH expedition in November - December 2018.

Larsen carefully chose a variety of lightweight, durable equipment tailor-made to withstand the extreme conditions of this journey. Among his professional tools that accompanied him and his team, were Citizen Promaster timepieces -- like the precision-engineered Altichron with a compass and altimeter, and the durable Promaster Tough, withstanding the most extreme conditions.

Incorporating Citizen's earth-friendly, powered-by-light technology, Eco-Drive, these rugged sports timepieces can keep any outdoor adventurer on track and on time.
