Random thickness of GMT movements??!??
How come the new Miyota movt is a travellers gmt with 4hz just as the Black bay pro is and still the Tudor is way thicker than for example the upcoming traska GMT with the Miyota in it.

The Tudor movements are sourced from Kineses. Breitling also has access to these movements, but opted to go with a Selita for their new Superocean for this exact reason. It was too thick.
It’s important to remember that the Miyota’s power reserve is something like 42 hours and the Tudor’s is 70. More power reserve requires a beefier mainspring, which means that it needs to be wider and the barrel is therefore thicker.
The Rolex is 100m of water resistance which helps the slimness. They list it at 12mm.
The Traska is 150m. The website states 10mm without crystal. Add another 1-2mm for the crystal.
The 200m on the Tudor adds 1-2mm with a thicker crystal and case back on top of an already thicker movement.
