High-Torque ETA FØ6 Quartz Movement

Swiss-Made with EOL Battery Indicator

The watch is powered by the Swiss-made ETA FØ6 high-torque quartz movement with 3 jewels and an End-of-Life (EOL) indicator. The movement provides hours, minutes, seconds and date functions, with the EOL function indicating when the battery requires replacement. The quartz movement was developed for reliable timekeeping in demanding aviation and military applications.

Bidirectional 12-Hour Navigator Bezel

Second Time Zone Tracking

The Navigator features a bidirectional bezel with a 12-hour scale, allowing a second time zone to be tracked alongside the main time display. The watch uses a high-impact Fibreshell case with a stainless steel back, providing a lightweight construction suited to the Navigator's aviation-focused design. The sapphire crystal provides scratch resistance, while the case is water-resistant to 6 ATM (60 metres/200 feet) according to product specifications for this reference.

Built for Field Use

The hour markers and hands are treated for continuous visibility in low-light conditions. The black dial retains the military-style 12- and 24-hour layout, while the black nylon strap completes the lightweight Navigator configuration. The WW194013BK-0001 is specifically identified as the U.S. Government version, with the model listed under Marathon's Navigator Date range.
