Did you try the nylon watchband as well? I have a set at home but I've been too lazy to try and swap it out. Did they not fit as well? I tried placing it above the bracelet and the links looked like it would fit. I should stop being lazy and try it out! I personally think the watch looks best on the bracelet though.
I've bought several watch straps from AliExpress. All fit terribly and are of terrible quality. I ended up modifying a "nylon" strap. The nylon is simply a wrap around a rubber interior. It works but is terrible in quality. However, I deal with the terrible quality since I find steel bracelets unbearably uncomfortable. I wish there were better options.
The end links to the straps are all the same no matter which seller from AliExpress. The end links are 0.5mm too small. They are also shaped incorrectly. When installed, the corners stick up vertically. This makes the watch look like there are pillars at the ends. I ended up removing the end links and using the end links from the steel bracelet.

Here you can see the nylon strap attached to the end links that came with the steel bracelet. The end links that come with the steel bracelet do not stick up in the air when worn. The major problem was that the nylon strap was made with an end link that was 0.5mm too small. I had to pry the nylon strap wider to make it fit the end link from the steel bracelet.

The strap is such poor quality. You can clearly see the nylon skin wrapped around the rubber interior. At certain spots, you can see where the wrap starts and ends like a sticker. It's especially noticeable around the screws:
However, the clasp isn't terrible and is quite comfortable:
