At the heart of this Navitimer is a self-winding mechanical movement delivering roughly 70 hours of power reserve. The chronograph measures to 1/4th of a second and provides both 30-minute and 12-hour totalizers, running at 28,800 vibrations per hour across 47 jewels. A screwed-in sapphire crystal caseback offers a direct view of the movement in action.
The round 43mm stainless steel case is fitted with a cambered sapphire crystal featuring anti-glare coating on both sides. The signature bidirectional rotating slide rule bezel — a defining element of the Navitimer line — frames the black dial, which is equipped with luminescent index hour markers and luminescent hands for legibility in low light. Water resistance is rated to 30 meters.
Completing the package is a black alligator leather strap secured by a stainless steel fold clasp, lending the watch a refined character that honors its aviation heritage. This example is in new condition and comes with its original box and papers, reference AB0138211B1P1.
