I've never understood the "catalog is too large" complaint. As buyers, more choices = good. You aren't required to buy every watch that is made. But if you are an AD I can see where a large catalog becomes an issue. I'm not an AD though, so....good for me.
This discussion had me go to the Omega website and look at their catalogue and in my opinion, it is too large. My reasoning is the following:
1. While Omega does make some classics, they also make a lot of seriously Fugly watches. I can't imagine who these models sell to, however, if/when that happens, I am sure it is at a substantial discount. This cheapens the brand and overall perception.
2. Model lines should be unique. For example chronos should be unique to one model line (Speedmaster) and this complication should not be in their diver model line (Seamaster). Seeing a diving watch with a chrono function screams poseur. Omega should not be all things to all people.
It is worth noting Rolex arranges their models in this way and it makes their models lines more distinctive and less confusing.
3. Too many sports models in the 42mm-44+mm range and not enough in the 38mm-40mm range.
4. Design language issues. Some watches have hands with a plain minute hand and a broad arrow hour hand, some watches have the opposite. Some have hands with both broad arrows. There is no consistency and if you ask why there is no historically answer. The watches look dated, not iconic. Personally, this inconsistency is why I would never buy and Aquaterra, Railmaster, or Heritage Seamaster
5. Some watchmakers do a nice job with two-tone watches (Rolex/Cartier/Patek), Omega isn't one of them.
Curating the catalogue is lying fruit, as would be coming out with better bracelets.
Just my opinion. I think Omega does a few things really well, and a lot of things very mediocre.
YMMV
