Any guess on what these Chinese astronauts are wearing?

Black dial, but it doesn't seem to be a Speedmaster....

I think it is a brand called Fiyta. I recall an article about them somewhere.

But, they may also be Patek Philippe Nautilus.

???? that is new knowledge to me

Doesn’t appear to be the prior space watch

On my last trip to China (2019) I spotted this advertisement whilst riding the Chongqing subway in Sichuan Provence.



The original model that the Taikonauts wore is somewhere around 54mm or even larger. This model below is the closest I could find. It's at 44mm with a thickness of 15mm. Movement is a Chinese equivalent of the 7750.

Finally got my hands on one, well... it's in transit. For some reason I am more excited about this watch then any other I remember waiting for. It will sit nicely beside my flightmaster Cal 911, Speedmasters' 3570 - 3572 and Bulova Lunar Pilot 96B258. More importantly, like all my watches, it will sit nicely on my wrist.

It's incoming also. It seems I have spurts. I read that they were big, so will post a pic when it gets here.
