The Marathon Pilot’s Navigator was developed in partnership with Kelly Air Force Base in 1986. The objective then remains today: a pilot’s watch with uncompromising quartz accuracy—capable of withstanding extreme altitude changes.

The case of the newly-issued 41mm NAV-D is constructed with CeraShell®—Marathon’s proprietary case construction made up of bio-sourced plastic and ceramic powder, with an aluminum bezel.

The CeraShell version of the Navigator has been enhanced with:

• Removable spring bars
• Radial mounted tritium tube insert, affixed into the bezel pip (improved visibility and protection)
• An aluminum bezel to deliver a more tactile rotation

This evolution of the Navigator lightens the mission load while upholding the durability and reliability Navigators are known for.
