I received the bracelet for the U1. At first after feeling the heft of it I said, "no way" thats toooo much. Thought I'd give it a shot though and I have to admit its a great bracelet on an even greater watch.
I was able to put the bracelet on without any trouble and I am not one thats typically capable of bracelet installation without screwing them up usually. It was easy and the bracelet well worth the pesos.
the Allen wrenches provided were perfect. I'd advise everyone to put them in a secure place afterword.
