while I think whether price is fair or not is personal opinion, justify the price because of their cost of production is not reasonable to me. Optimization of the cost of production is the problem for Ming, not for customer. Customers should only care about what customers get. That's it. If you like their design, or whatever the watch can bring to you, and with you the price is fair, that's totally fine, go ahead. But objectively, with around 20k, there are tons of options with interesting history, great design, with unique movement and beautiful decoration, from big brands.
And I don't agree that this movement has MB&F quality. Even with the rendering, I cannot see the comparison can be justified.
