I bought one from Homer. Looks exactly like on the pictures. Very satisfied
Compare to the real one: it is difficult to say. I'm not an expert in Navitimers.
Homer's rep is VERY GOOD but it is a rep.
If you look the rep alone, it is very difficult to see the difference btw. the rep and the real watch. But if you make a face to face comparison (I had chance to compare both in a shop), there is no question (even for a newbie like me).
The quality of the rep is lower especially:
* weight;
* feeling of the chronograph buttons;
* appearence of the steel bracelet ;
* readability of the chronograph;
* ...
In few word, Homer's Navitimer reps are VERY good. But don't expect to find the quality of a 3000$ Breitling in a 300$ rep. From my point of view, rep is the choice when you cannot afford the real watch.
