I have three Invictas, two dive chronographs that are made to look like a Rolex/Breitling sport type diver, and the other is a dress watch.
All were right at $100. They were all bought by me new at an auction about 8-10 years ago. All run great, look great, and have held up very well.
They all have mineral glass crystals that haven't scratched, and well made bands that haven't bent out of shape or had the clasps work loose. The cases are quite sturdy and where usually my constant sweating will pit the backs of the cases, none of these have had that problem. I can buff the stainless bands with my Dremel and some jeweler's rouge and they look brand new.
My watch guy told me that the two chronographs have a Swiss ETA movment (nothing exceptional, he said it is a solid movement along the lines of a upper end Seiko) and the dress watch has a Japanese Miyota movement which is pretty average. All keep great time.
I can't speak to the quality of the newer made watches, but the older ones I have are quite a value. If you have an opportunity to see the watch in person and to identify the origin of the movement, I think that would be the telling signs as to what type of quality of watch they are making these days.
