Sell it. Buy it back after 100K

if it's just a watch for you, sell it if you have great memories with it ... keep it

If it was a gift, keep it and the memories of that person. If you bought it for yourself, sell it.

Depends how attached you are to it and if it holds any sentimental value. They hold their value quite well too and some models appreciate too. If you lost it, how would you feel?

I don't understand the question

Yes
