The watch was from ebay, it did fail the pressure test so the watch shop said, the gaskets and possibly the crown needs to be replace, they suggested i could “upgrade” the movement to the NH36 movement?

Should i do this or keep the 7s26 movement.

i want to test the movement out and see if i think it is worth it or just fix it so it passes the pressure test.

Also i am thinking the bezel could be aftermarket?
