Found this in my stash while looking for something else. There is no case, and the dial is poor. But the bi-metallic temperature compensating balance wheel is good, as is the blued steel, Breguet hairspring. Shown without the stem as the movement comes with its dust cover, and the stem had to come out. 15 Jewels, a 5 million serial number, Omega caliber 17 L. This movement has appeared here as a T17, but my Bestfit book calls it a 17L. If you have a case, with a basket case movement, this might be for you. Unfortunately, I will not part it out. I have never offered anything for sale before, but I have references. Asking $500.00.
