Seikomariner / GMTeiko
Dive and travel watches built in the spirit of the Submariner, GMT-Master and Yacht-Master, every one of them 40mm. Most run the Seiko NH35 automatic. The GMT models use the Seiko NH34 instead, which drives a genuine independent 24-hour hand, so a second time zone is read at a glance rather than counted out. Sapphire glass with anti-reflective treatment throughout, and a choice of bezel, dial and bracelet on each build.
