Hi everyone, I'm new here and I'm looking to buy my first datejust (used). I tried on the one in the picture and I just love it, but I'm a bit concerned about how it will hold up. Ideally I want a datejust that I can wear everyday for a long time, maybe decades. I'm not sure how old this watch is, but it's probably more than 20 years old. Would it still hold up well or should I look for a newer model?
