Complements the timepiece's name, the TimeWalker Extreme Chronograph DLC. The Diamond-Like Carbon coating on the case also reflects the Extreme nature of this watch.
The watch is meant for adventures from how I see it!

(Not for swimming though as it is only WR up to 3 bar)
Yet it needs to be elegant in a sporty way like other TimeWalkers. Hence a strap that is more resistant to the elements (abrasion, water and fire resistant) works very well!
Your use case is possible Patrick! But for truly extreme sports, I wouldn't recommend a sporty elegant timepiece still. It will be too precious and beautiful for me to risk it
