Marek Holeček


Personalities who share same passion for adventures and explorations as our watches. Whether underwater or high in the mountains, these people aren't afraid tu push limits of human possibilities and constantly experience life out of their comfortable zone.

Marek Holeček

  • The most successful Czech climber and holder of two Piolet d'Or awards

    Marek is one of the best climbers in the world. Still, he is also a writer, filmmaker, and endless optimist who loves life, not changed by his harsh experiences in the mountains, including the tragic loss of his climbing partner on one of his expeditions. He is driven by an unquenchable passion for climbing where no one has gone before. The constant sense of failure also pushes him to push the limits of his abilities. Like Chronotechna, he treads his path as he avoids the "mass" mountains and chooses unheralded eight-thousanders for his expeditions, where he seeks new routes. He has undertaken over 4 expeditions worldwide, and dozens more are yet to come - where exactly he doesn't know yet, but one thing is sure. The Chronotechna watch will be there with him.

"We have as much time as the universe has given us, and there is no room to waste it. One feels as free as abird at the top, though the satisfaction of reaching the world's roughest peaksis like a twinkling. Desire on the walls often turns into a mere effort tosurvive. But one thing is sure. The hands on the dial will always turn in theright direction."

David Vencl

  • Czech freediver and world record holder in swimming under the ice

    David Vencl is the most competent person regarding time perception, as he can last underwater for over eight minutes in one breath. The Czech freediver is in water like at home, and his records include a dive to a depth of 84 meters without an oxygen device. The world of freediving and watches have more in common than you might expect. When he dives, he has to be precise, meticulous, focused on every detail, and not allow himself to make a mistake. Moreover, every dive revolves around time because every second underwater makes a big difference. Especially when David's specialty is cold water - freezing water. He's been enjoying ice baths for many years, promoting them, and in 2021 he stunned the whole world when he broke the world record for swimming under the ice. He swam almost 81 meters under the frozen surface only in his swimsuit.

  • David Vencl, Czech freediver and iceman - wolrd record holder in distance swam under the ice without a wetsuit

"I enjoy being able to do anything underwater, I am free in it, and theoretically, I can dive at any depth. My only limit is time. Time is the absolute master of the situation; everything revolves around it. That's why it's essential for me to have a watch on hand that is accurate and reliable even deep below the surface."
