I assume this remote site will be unguarded? Expect rubbish, empty cans, used condoms etc there. That's assuming nobody does damage to the clock itself, either on purpose (stealing) or not ("what if I put a wood stick inside..."). Some people would start climbing it just because.. and some of them would get hurt or die. Police would come and seal the place.
"It's one day hiking!" -- yes for now. Human settlements expand, and within few years maybe the distance from nearest settlement would be half. Also if the place becomes famous, people would pave ways to it (you know, as tourist attraction).
I guess I'm an old fart.
