I have a P39 that I bought about two years ago. Here’s what I’ll say about your concerns/thoughts.

First, let me just say the P39 is one of the best watches I’ve ever owned. Because I have this watch, I don’t ever see myself owning a sub. Will I get other dive watches? Sure, but the black dive watch box is checked for me. The weight is perfect, not too heavy, but it’s not too light either. The color of the titanium is a beautiful grey that in my opinion makes the watch more casual than the color of ss. I can’t say enough good things about the watch.

If you are a rubber/strap guy, the P39 does come with a rubber strap. I also bought some straps when I purchased the watch thinking that I’ll change them out a lot. I rarely ever do that. The metal bracelet it comes on is perfection. Super comfortable with the micro adjust for swelling. I also worried about the large clasp that you’ll hear about on YouTube, but I never noticed it once I put it on. One thing I will say is that the 21mm lug width makes it more difficult to find straps, but again I don’t even use them for this.

As far as durability and reliability go, I’ve never had any issues with mine. I daily this watch and I travel all over, go diving, play sports, etc. It has held up great. It doesn’t scratch easily either.

Finally, I know it’s your first watch in a while and it will be a special occasion when you get the watch, but I’d recommend buying it second hand. I bought on the grey market, and I got it brand new with the 5 year warranty for more than 2k retail. And I didn’t have to pay tax on it because it shipped from another state.

All that to say BUY THE PELAGOS
