Help with choosing a PAM

[exp90]

Hi all - have been a long time fan of Panerai and close to pulling the trigger on one - so wanted to ask this friendly group of like-minded Panerai enthusiasts for any opinions, e.g. how they wear, scratch resistance, quality (or problems) of movement etc, any opinions/info very much welcomed. I'm looking at:

• Luminor GMT PAM01441
• Luminor Due PAM01124
• Submersible PAM02973

The GMT is of course bigger, and I've 6.5" wrists, so usually I find 44s a little large. In this case its a matt black case, so may be fine - have yet to try this one on. I tried the Carbotech PAM02661 on previously, but couldn't get past the blue, so forgot the fitment.

The Due series I was set against originally, but the blue dial has really worked on me.

Lastly the Submersible in 42mm is a tank, but fits incredibly well.

The GMT is likely my first choice, but I have little working knowledge of how the movements have proven to be over time - and not 100% clear on the hardiness of the carbon casing.

Please give some points of view! Thanks
