Since its first development in 1952, the Navitimer has been the flagship watch of the Grenchen-based brand, and though it has been mechanically altered and improved throughout the years, it has never faltered in its role as a navigational aide and icon of modern horology. All watches are sold as is. Webb's make no guarantee of the future working order of the watch or battery life, and watches may need to be serviced to improve accuracy.
