Why This Watch Matters While the Navitimer might be one of the most iconic aviation watches, finding one cased in yellow gold is a true rarity. And the golden AOPA emblem on the black dial isn't too shabby either. The Full Story The Navitimer was definitely made with the pilots’ well-being in mind: it basically took the functionality of the earlier Breitling Chronomat one step further in displaying all the essential scales and rulers for flight-related calculations. The final legibility is impressive, and testifies to Breitling's know-how with chronographs. While the early examples of the Navitimer offered an all-black dial, the sub-dials eventually became silver to offer the reverse panda configuration that Breitling had pioneered with the SuperOcean. Finally, the AOPA emblem (for Aircrafts Owners and Pilots Association) truly shows that the Navi was not a marketing ploy, but more of an essential onboard tool.

The engravings on the caseback are also deep, despite some superficial scratches. The gilt dial is also in a very nice shape, with no blemishes to regret. The AOPA emblem is clearly visible and the silver sub-registers are free of any specks. The chronograph function works well; it is definitely a golden example (pun intended).
