Marathon has been building general purpose field watches for Allied forces since 1941. This one carries that lineage directly manufactured to the same U.S. military standard with direct roots to the legendary GG-W-113 field watch. A slim build in a high-impact composite fibreshell case, it weighs almost nothing on the wrist. Tritium gas tubes ensure the dial reads clearly at any hour with a pressure crown, date at 4:30, sapphire crystal, and accuracy to -0.3/+0.5 seconds per day. This watch gets out of the way to tell you the time..View Marathon 34mm Military Field Watch by Marathon on our site for more info. - The Bespoke Post store has the greatest gear from the world's best small brands.
