Just wanted to share that I did encounter a bad clasp and had to exchange mine right after it got delivered (the inner clasp wouldn’t click close, as opposed to the outer clasp like Tamara Kalinic’s). I am a little paranoid now, especially since the parts are so fine and delicate looking. The SA told me somewhat matter-of-fact that I’m probably going to need servicing in the future, since she noticed her own bracelet (a regular JUC, not a Clash) doesn’t click close quite the same as when it was new. I’m glad to see that many people have no issues.
