Here is my Omega Flightmaster c. 911. It’s one of my favorite vintage Omega chronograph watches. These watches were made from 1969 through the early 1970′s. It measure about 43mm wide without the crowns and is about 15mm thick! I have a thing for black dials and you don’t see to many vintage watches with them. And when you do find them, they don’t look as nice as this one. It’s very large, clean, easy to read, and is in excellent condition for it’s age. It has the Omega 911 movement which was derived from the 861 movement with the added GMT complication. The 861 movement was derived from the 321 movement. I had watches with all three of these movements and always had great experiences with them. The crown at 3 o’clock is your typical watch winder and time setter crown. The button at 2 o’clock starts and stops the chronograph, indicated by all three of the orange hands. The botton at 4 o’clock resets the chronograph after you’ve stopped. The crown at 10 o’clock rotates to set another time zone, indicated by the blue hand in the center. The crown at 8 o’clock rotates the inner bezel. A lot of people are walking around these days with watches that have rotating bezels and they don’t even know how to use them. It’s a great way to keep track of time, like when you put coins in a parking meter or something. You simply rotate it until the arrow is pointing to your minute or hour hand and that’s it. The next time you look at your watch, you will be able to see how much time elapsed. You can also set it to a future time if you need a reminder.
