The Desert Tan version features a high-impact composite Fibreshell case with a black dial, red-tipped seconds hand and date display at 4:30. The case measures 41mm in diameter, 13mm thick and 48mm from lug to lug, with 20mm lugs. A scratch-resistant sapphire crystal protects the dial, while the bidirectional bezel features a 12-hour scale.

ETA High-Torque FØ6 Quartz Movement

The watch is powered by the ETA High-Torque FØ6 quartz movement with 3 jewels. It features hours, minutes, seconds and date functions, with the red-tipped seconds hand and date display at 4:30 forming key elements of the NAV-D configuration. The pressure crown and high-impact composite Fibreshell case provide water resistance to 6 ATM, equivalent to 60 metres.

Bidirectional 12-Hour Bezel

The NAV-D features a bidirectional bezel with a 12-hour scale, allowing it to be used to track an additional time zone. The Desert Tan case and bezel frame the black dial, while the sapphire crystal provides scratch resistance and protects the display.
