I have Pre, and post Invicta Glycine pieces. The older model has a few better touches like some of the engraving on the rotor isn't quite as distinct on some newer pieces. Other then that and the lbrand logo slightly changed can't spot tons of important differences. You can tell the pre-Invicta models have a thicker version of the winged logo. The newer have a slightly thinner, more detailed look to the winged logo. You can find tons of the pre-Invicta on the sales if you look at the logo. Nice watches either way. If you like what you see don't be afraid to give one a shot.
