. Last one I got was made by Casio - Made in Japan. The one from a few years ago was from Casio - Made in China. It is embossed on the back of the buckle. The part number may be the same, but the straps are slightly different. This latest strap I've received (made in Japan) is made from a slightly thinner material (about 1.78mm vs. 1.88mm for the ancient Chinese strap) and the mounting holes are slightly larger in diameter. The market vendor I bought from included two new spring bars (pins) that were 22mm long, but they were much thinner (1.4mm) than the old ones (1.8mm), so I reused the old ones . Even on the old bars, the large mounting holes make the strap a bit messy on the case, so I'm trying to find thicker ones now. Of course, thinner straps of the right length will work, but they feel "cheap" because the strap doesn't feel secure. So yes, this is the correct Casio "factory band" for the AMW-320D watch, but depending on the FACTORY, the band may not be 100% identical to the band you are replacing. And whether or not you get spring bars is up to the seller, as Casio doesn't include them. And even then, the bars you get might not be quite right.
