Karen Kyllesø is a Norwegian polar explorer whose calm precision under pressure has already redefined what’s possible at a young age. On 13 January 2025, at 21 years and 249 days old, she became the youngest person to ski solo and unsupported to the Geographic South Pole, completing the ~1,130 km Hercules Inlet route in just under 54 days while hauling a ~100 kg sled.

The young explorer and adventurer embodies the Prospex spirit: precision meeting courage in the world’s harshest environments. Across Antarctica’s endless white expanse, she navigated sub-zero winds, whiteouts, and a featureless horizon where distance deceives and every decision is measured. In a place where the sun never sets, watch becomes an essential instrument—structuring ski intervals, anchoring safety checks, and maintaining cadence when visibility and instruments are tested. Clear legibility, dependable performance, and glove-friendly ergonomics turned a tool watch into a mission-critical companion.
