It's the same problem discussed every couple of pages with demand in China, these reps are made for the Chinese market. If Omega markets the speedmaster widely to the Chinese market more people would want it, it will encourage better reps.
Until then they have no reason to make a watch that won't sell in large numbers domestically. At the end of the day the Speedmaster will be the watch fanatics watch of choice.
Reps are a business decision, not a passion project.
There are a lot of interesting case studies out there on luxury watch market in China and how it's different to the rest of the world. The accumulation of wealth over the last 50 years of economic boom in China. The introduction of Rolex in China, the history and it's placement as status symbols domestically thorough it's marketing strategies.
Advertising is also very different to how we have it in our part of the world. Media has heavier control from the Chinese government so brands have very different marketing approaches.
Unfortunately Omega has never made as big of a dent in China compared to Rolex or Patek. Which is why you see multiple factories repping their watches at an extremely good level at this point.
On the other side the best Omega are solely left to VSF.
