MARATHON WW194013 NAV-D Navigator Quartz with Date

41MM NAVIGATOR QUARTZ W/ DATE

The Navigator Class of Wristwatches were developed in partnership with Kelly Air Force Base in 1986. The Navigator issued today was last revised in 2019 with the addition of a sapphire crystal, steel crown and crystal retaining ring, as well as an easy-access battery hatch.

Commonly known as the Pilot’s Navigator with Date (NAV-D) is a modified version of the standard issue navigator that features a Red Tipped second-hand and a date complication at the 4:30 position on the dial.

TRITIUM GAS TUBES

The NAV-D uses self-contained tritium gas tubes to ensure constant visibility in low light situations. A gas tube is placed on each hour marker and hand. These tubes are self-illuminating and contain an isotope of hydrogen, that will not dull down over time like photo-luminescent paint.

CONSTANT ILLUMINATION

SHOCK RESISTANCE

The NAV-D features a composite fibre shell case that offers shock resistance with lightweight durability, allowing it to withstand even the harshest environments.

EXTENDED BATTERY LIFE

The NAV-D is equipped with a low-power consumption movement, with an EOL (End- of-Life) display, whereby the seconds hand advances in 4 second increments when the battery needs a replacement.

OVER 4+ YEAR BATTERY LIFE

SWISS CRAFTMANSHIP

Inside the NAV-D is a Swiss-made, 3 jewel, ETA FØ6, quartz movement. These watches are hand-assembled in La Chaux-de-Fonds, Switzerland and guarantee the highest level of craftsmanship and accuracy

GENERAL OPERATIONS & MAINTENANCE

Clean watch often.
Clean regularly using rubbing alcohol, a toothbrush and a microfibre cloth.
Service regularly.
Regular servicing every six to eight years will help to keep your movement running with Marathon-level precision. For servicing requests, contact our team directly at customerservice@marathonwatch.com
Always set it forward.
During events such as daylight-savings, you might be inclined to wind your watch back an hour, however this can put undue stress on the movement of your watch. Always move the hands forward to reach your desired time setting.
Securing water and dust resistance.
To ensure water and dust resistance, gently push the crown of the watch back in until it is fully seated against the case, ensuring a tight seal.

SETTING THE TIME

Pull the crown from position 1 to position 3.
Turn the crown clockwise to adjust the time.
Ensure correct AM/PM settings so that the date wheel changes at midnight and not mid-day

SETTING THE DATE

Pull the crown from position 1 to position 2.
Turn the crown clockwise to change the date.

CAUTION: Do not adjust the date wheel between 9pm and 3am as this may damage the watch movement.

SECURING THE CROWN

From position 2, push the crown into position 1 to ensure optimal water and dust resistance.

BI-DIRECTIONAL 12-HOUR GMT BEZEL

The NAV-D comes with a 12 hour GMT bezel which allows for easy tracking of time in two different time zones.

Rotate your bezel to align the 12 o’clock bezel marker to local time-zone offset. Read the watch as normal for home time, and off the bezel for local time.
