While the new Unimatic UT1-GMT Tool Watch derives its looks from dive watches, the UT4-GMT Tool Watch recalls previously released field watches — hence the simplicity. But that doesn't mean you should discount the new reference as simply a hunk of stainless steel. This new timepiece from Unimatic's second-ever permanent collection is durable, yes — MIL-STD-810H Certified with a proprietary 360° Protection gasket for the movement and 300 meters of water resistance — but it's functional, too. A digital-style GMT window sits at 12 o'clock, while phantom ladder hands and a black reverse lollipop second-hand with a vibrant orange tip on a matte black dial with printed Arabic numerals help you tell the hours, minutes, and seconds where you are, and a subtle date window at 6 o'clock helps remind you what day it is.
