The new 41mm Steel Navigator w/ Date (SSNAV-D) has received many engineering improvements when compared to the design of its predecessor. One of the biggest updates is in the form of the new quartz movement: the 3 Jewel ETA F06.412 with HeavyDrive-PreciDrive.
Now the most precise watch in the Marathon electric watch lineup, the Steel Navigator w/ Date features an accuracy of ± 10s/year, operating at 32’768 Hz. This is made possible by the combination of ETA’s venerable quartz technology, as well as customizations specifically for Marathon. With a deviation of -/+ 10 seconds per year, ETA’s Precidrive technology makes it one of the most accurate quartz movements on the market, 10 times more precise than standard movements.
Marathon has improved the shock protection of the Steel Navigator by improving both the movement as well as the protective cage surrounding it.
Housed within this particular movement is ETA’s HeavyDrive technology, offering shock detection and management by way of an integrated circuit. When a shock is detected, the motor applies a counter force to prevent the hand from skipping and affecting the accuracy of the movement.
Further stabilizing the movement is Marathon’s fully revised movement mounting system. Inside the Steel Navigator w/ Date is a steel ring that secures the F06.412 in place with three screws. This is engineered to protect the movement against unwelcomed forces such as torque, vibration, and impact.
The Marathon Steel Navigator w/ Date also features ETA’s PreciDrive technology. This technology consists of a thermo-compensation unit that monitors and reacts to changes in the watch’s internal temperature as well as the temperature of the surrounding environment. The thermo-compensation unit of the F06.412 is sealed in a vacuum-insulated, brass-plated housing.
These features, in combination with Marathon’s addition of a screw-down crown and improved water-tight gasket system, allow the movement to be unaffected by humidity.
With the F06.412 generating a longer battery life – approximately 86 to 94 months – the watch poses benefits to the environment and consumers alike. Less batteries equals less waste, plus reduced hassle for users with fewer battery replacements over the watch’s lifetime.
All F06 movements have a built-in EOL (End of Life) Indicator that will notify the user to change the battery within 3 months of the battery expiring. You’ll note that the secondhand will begin ticking in a pulsed, four second interval pattern. The watch will continue to display the correct time until the battery is fully depleted, however the visual effect will alert the user to the need of a battery change with time to spare.
Another update to the internal design of the Steel Navigator w/ Date is Marathon’s new battery hatch spring. In the past, models have featured a standard spring - a small piece of metal with prongs that sits in between the battery hatch and the battery itself. In this new version, the spring is mounted to the inside of the battery hatch cover, preventing the spring from being misaligned or lost during battery change.
A first for any Steel Navigator, the new SSNAV-D model includes a date function. This feature was introduced due to the popularity of the current Navigator with Date.
Other features include- Enhanced tapering of lug for a more comfortable fit; Bezel size increased for improved grip with flight gloves and inset-painted indices for better legibility; Sapphire crystal for increased altitude rating, scratch resistance, and clarity.
The Marathon Stainless Steel Navigator Pilot's Quartz is a highly accurate watch built to strict military specifications under NSN: 6645-01-698-4275. Designed for pilots, parachutists, and law enforcement, the watch is made to withstand the many challenges that are faced in a professional or everyday environment. This watch uses self contained Tritium gas tubes to ensure constant visibility in low light situations; therefore, a gas tube is placed on each hour marker, hand, and at the 12 hour marker in the bezel. Tritium tubes are self illuminating gas tubes which contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photo-luminescent (glow in the dark) paint which requires an external light source to create a glow.
The Navigator Stainless Steel Pilot's Quartz is made in La Chaux de Fonds, Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Powered by a Swiss made, high torque, 3 jewel ETA FØ6.412 Precidrive quartz movement, it guarantees you a high degree of accuracy in timekeeping. The ETA FØ6 movement is accurate to -/+ 10 seconds per year, and also includes an End of Life (EOL) indicator that will advance the seconds hand once every 4 seconds to inform you that a battery change is needed. Replacement battery is a 371 cell.
