If you have a lot of time, and a diamond needle file or Dremmel, you can adjust the Parnis bracelets to fit.
About 2mm needs to be removed from the "curve" to get the spring bars lined up to fit the case holes.
When I did this, the Parnis sub was around £50 and used a slim clasp which suited the PRS4 PVD well.
The current straps have a chunky glide-lock type clasp which will also work, but be little bit more bulky on the wrist.
The same modification can be done to any 20mm bracelet with solid end links.
The PVD Parnis is on the right of the watch box - Ali have the Bliger straps for £17 (+vat)

But it would be more cost efficient to buy a complete watch for £56 and put it on a nato. The Miyota movements are very accurate. Search for Bliger on Ali-Express.
