Deadlines, invoices, meetings: modern days run on dates. The Marathon GPQ-D in black, reference WW194015BK-0108, is a 34mm Swiss quartz field watch that keeps up with all of it, adding a date at 4:30 to a clean dial with no government markings and tritium that glows around the clock.

This configuration is ideal for the office or the job site. The black fibreshell composite case is light and slim at 11.5mm, sliding easily under a shirt cuff, and its matte surface never looks flashy. The dial shows only the MARATHON name with bold numerals and 12- and 24-hour scales, keeping the design restrained enough for business casual. Self-powered tritium tubes on the hands and markers mean you can check the time in a dark car or during a power cut.

Inside is the Swiss ETA F06.115 HeavyDrive quartz movement, a high-torque caliber with an end-of-life indicator to let you know when the battery is due. The watch is built to MIL-PRF-46374G and finished with sapphire crystal and a black DefStan nylon strap, sturdy and simple to swap if you want a different look.
