I imagine if and when they get listed on their site anyone should be able to buy them if they are available. The SS versions are about $ 50.00 +S&H. I picked up this one back in 2016. It was a kit that could be converted into 22mm or 24mm buckle with the supplied parts. I paid 50 euro, about $ 55.00. I also ordered a few straps that was about $ 78.00 for both straps. (70 euros)
