What does NBY mean? NBY stands for No Barriers Yaeger. It represents the uniqueness of the design. Especially the âYâ. It stands for the drive, for the clarity and the expressiveness of the NBY pilot watch. NBY has a clear and unique design approach that you immediately recognize. The focus is on a clean look using a cockpit style familiar to pilots and aviators. NB Yaeger watches are made in Germany and use Swiss movements.
