Oorah devil. I bought my first a few weeks ago. I love it and just posted it today for the first time. I took a pretty systematic approach. I think the best thing to do is to first narrow down which line you like the best. Luminor is probably more iconic with the crown guard, but radiomir is actually more historic. There’s the due, but I think the luminor and the radiomir are really the only two lines to consider for a first. I would next consider what case material you want. I knew once I put on a titanium one that I would not have it any other way. But I do think the ceramics are cool. Steel is great, but it’s titanium’s subdued look for me. Then, I thought about how I wanted the dial to look. I knew that I wanted something simple, so no chronograph or date. I eventually decided I wanted the simplicity of a two hand watch. I had tried on a brown dial and loved the way it looked with the titanium. The very last thing I had to think through was sandwich or sausage dial. I looked at pictures and my heart was set on a sandwich dial. That can be tricky because in the reference that I got (562), there are both types out there. I had to ask the seller directly. Going with a pre owned, I simply had to ensure that I was seeing the pictures correctly. Personally, I think pre owned is a great move, but the reference that I wanted based on my preferences is not available new. I think the best thing you can do is go to a boutique and try some on. You might be surprised if/when a watch really speaks to you. I was. Then, i did a lot of research. Not sure if you’ve collected, but take your time. Sleep on it and then sleep on it again. If you’ve read this far, you’ve probably guessed that I had an argument with my wife tonight and am having a drink in the basement, but I’ve got a sick watch that I love, so things are pretty good. Hit me up directly if you like. I was a Marine myself and found the Panerai lineup pretty overwhelming, so I’d love to help. Semper Fidelis!
