My first Rolex was an Explorer II 216570 with black dial and I absolutely loved that watch. It was rarer than the GMT-Master II or Submariner, and didn’t have the ceramic bezel, which I found to be a little too glossy and “luxe” for what I was looking for in a watch at the time. I kept and wore the heck out of that watch for almost six years until I just felt like it didn’t speak to me anymore. The 42mm wide “Maxi” case seemed too big and the big, thick hour and minutes hands just began to bug me. I can’t explain why I was so dead set on the 216570 rather than the older 16570 at the time but I can certainly say that now, in 2025, the Rolex Explorer II 16570 is not just my preferred iteration of the modern spelunking watch, but an all-timer from Rolex.
