I almost sprung for one of the vintage style, NH powered, titanium Aliexpress watches a couple months ago.
I decided to hold out till I could do some vintage hunting.
One thing to note: the TMI/"seiko" movements are not all Japan made. They are from the same parent company, but most are made in China and maybe Malaysia? That's why they are on Aliexpress for $39.
I have nothing against China, but Japan quality is VERY different from China & SE Asia. It isn't a technology issue, it is a cultural one.
