Due to their low height it fits loosely under the shirt cuff. She is elegant and sporty at the same time, but has quite toolige properties. Because it's designed for exploration and has already survived the Mount Everest.
The build quality is top notch typical for Rolex. The Oysterband can wear very comfortable.
The only gripe I have (and therefore there is no 5 star): The minute hand is clearly too short. When setting the clock, it is annoying that the minute hand does not reach the minute. There's asked for me too much judgment.
But otherwise, the Explorer I is a great clock!
