Omega might only make watches in Switzerland but it does have multiple facilities, more than most Swiss watch makers which enables them to produce more but still maintain high standards. It’s hard to know exactly how many watches Omega make per lineup but there are rough estimates.
Take one of their most famous watches of all time, the Moonwatch, they roughly produce 10,000 Moonwatches per year. However, they make more than 190,000 watches in their seamaster line per year.
This is because it takes a lot longer to make a chronograph movement and because of the added complex nature of it, hence they cannot make as many as a simpler dive watch with only a time and date function. But Omega does try to spread the amount of hours it can spend making watches evenly across its different ranges.
A fair way to make their watches and it then naturally means the watches that are easier and less complex to make will have a higher production output compared to the their more complex watches.
