BREITLING U.S. NAVY “AN” NAVIGATIONAL CHRONOGRAPH POCKET WATCH (WAKMANN-SIGNED MVMT)

An authentic and historically significant military timepiece, this Breitling “AN” (Army-Navy) navigational chronograph pocket watch was produced for U.S. military use during the mid-20th century, when precision timing instruments were essential to navigation and flight operations. Pieces like this were used to calculate speed, distance, and position—serving as critical tools rather than simple timekeepers.

The black dial is designed for maximum legibility, featuring bold Arabic numerals and a clean two-register chronograph layout. A faint but present Breitling signature sits at the center, reinforcing its origin while reflecting the utilitarian nature of military-issued instruments.

Movement

Inside is a manual-wind Swiss chronograph movement signed Wakmann. During this period, Wakmann acted as Breitling’s official U.S. partner, supporting the importation, assembly, and servicing of Breitling timepieces for the American market, including those tied to military supply. The movement is running well, with chronograph functions operating as intended.

The caseback is engraved with U.S. military specifications, including AN designation, stock number, and contract details, confirming its role within military procurement channels. The case shows honest wear consistent with age and service.

Often compared to the Hamilton Model 23 navigational chronograph, Breitling examples like this are encountered far less frequently, making them especially appealing to collectors of military timepieces.

This is a military instrument with provenance—a functional artifact from a time when accuracy and reliability were mission-critical.
