HappyHoundsIt's a great size. 40mm is pretty standard for a midsize and is similar to the Rolex Submariner or Omega Speedmaster, some of the most classic watches of all time. I have smallish wrists, I think 6.5".... so these 40mm watches wear perfectly to ever slightly large on me. I also have a Panerai at 44mm and that thing is definitely big, but I still like it.
