My colleague Mark covered the announcement with his original intro, and that story includes the link raw specs, so I can be brief. The Pelagos FXD link GMT measures 42mm wide, 52mm lug to lug, and 12.7mm thick. Most of this is to be expected as the FXD has largely link held to its original dimensions (with the chronograph examples coming in at 43mm), but there is some context to this thickness when considering it's a Tudor GMT. We can get into that shortly.

As the name would suggest the Hamilton Khaki Field Mechanical 38mm is you guessed it 38mm in diameter. There's a 42mm version of the Khaki Field Mechanical and link an automatic version with different dial link styling and configuration but even on my 7.25" wrist and tall frame I'm dead set on the opinion this is the platonic ideal of what a link field watch should be. The original Khaki watches were 33mm but modern tastes have changed and 38mm feels like the perfect sweet spot.
