I had once an old navitimer and sold it off long time ago.
I believe its had the 7750 movement and wobbles a lot. You can actually feel the strong vibrations...
Fine workmanship to the details with anti glare coating in blue hue. Dome sapphire. The pushers clicks faintly at every push and no slipping. The dial prints is finely executed....
A great and nice watch to own. But IMHO, the dial is too busy and I gave it up.
