The Marathon Arctic MSAR Automatic features a white dial with black markings and a bright red seconds hand. A white dial watch is more easily read in very bright environments and conditions, such as in the Arctic during the summer months.
The Marathon Anthracite GSAR case has been completely sand blasted then treated with a full black anodized treatment which is three times harder than stainless steel, giving it a striking stealth-like appearance.
The Marathon Pilot Navigator gets an update. It now comes with scratch resistant sapphire crystal, a matte 316L stainless steel crown, and a battery hatch in the case back for easy servicing.
