Ah. On closer look it does look more like the Aquanaut. Not clear on my phone screen. No, don't quite like it, I much prefer the Nautilus. It's a toss-up between the Royal Oak or the Nautilus really. Will try and see which keeps me awake at night. Ha!Medtech- I prefer the perpetual calendar on the PP, or the FPJ. I'm biased, however, because I like dressier watches and my perpetual is on a dressier watch too. Would go for the FPJ though.
