[Hopefully, this message get across to the Sinn people]
I bought the U1 all black tempus last year because I wanted to have a very tough everyday watch that suits my active lifestyle. I like the U1 All Black very much EXCEPT its butterfly buckle really easy to be released. So easy that I now have trouble wearing it in and out of the water. With one stroke of my wrist, I can release the buckle. See this demo I recorded:

Even if I wear it on a normal day, I can easily release the buckle say when I move boxes around the office. The frustration can be embarrassing as well.
Now that U2 also come with black, I have ordered a U2 black buckle and will replace it later. See what will happen. But so far, it's been very frustrating.
If there is one tiny thing that the Sinn designers will have to do now is to greatly improve the U1 butterfly buckle. It is unsecured and useless for what I wanted as a tough watch.
Please do something so that I can keep my faith in U1.
