Pelagos LHD, or Left Hand Drive. Inspired by a bespoke model of the Tudor Submariner made in the ’70s for the French Navy, the big and rather unexpected difference between the LHD and previous versions of the Pelagos was that the case had been flipped, putting the crown on the left side. But this wasn’t the only difference, as Tudor also changed around some colors and some details, giving the watch a more stylized appearance than that of its siblings.
