Mountaineer Christine Jensen-Burke will wear a Sinn U200 on her latest expedition in Nepal, where she will climb three peaks, each above 8,000 metres.
Jensen-Burke recently became the first New Zealand woman to climb the highest mountain on each of the seven continents, an achievement that also made her the third fastest woman in the world to complete the Seven Summits.
Her current expedition will see her climb Lhotse, the fourth highest peak in the world, as well as Gasherbrum I and Gasherbrum II, the 11th and 13th highest mountains in the world, wearing a Sinn U200.
"In practical terms this means the watch will reach about 8,500 metres above sea level," the brand says.
The Sinn U200 has a 37 mm case made from high-strength German submarine steel, and has a bezel made with TEGIMENT Technology that makes it especially scratch-resistant. The watch is functionally reliable from –45 °C up to +80°C, and is low pressure resistant. It is powered by ETA 2824-2 self-winding mechanical movement, and has a matte black dial with luminescent indices.
The U200 is tested and based on European diving equipment standards, and certified by Germanischer Lloyd, Hamburg. It is pressure resistant to 2,000 metres diving depth, and has a captive diver's bezel with minute ratcheting. Ar-Dehumidifying Technology prevents fogging and enhances the reliability of the timepiece, and a crown at 4 o'clock prevents pressure on the back of the hand.
"I’m pretty excited that I'll have a watch this time that is designed to operate at temperatures down to -45 degrees," Christine Jensen-Burke writes at her blog. "Although I’m hoping I don’t get to test it to its limits because that will mean it's pretty darn cold! No more frozen timepieces and foggy dials! This watch is capable of being waterproof to an amazing 2000m under the ocean. I’ll be testing it high up on in the mountains!"
