Here, unfortunately not. The alarm clock is easy to use, there is vibration or audible alarm and the guard test the vibration seemed to be quite strong. Also, the display can be illuminated liked.
Awake I am never, while I have already a very light sleeper. On top of that the part is very clunky - wear a wristwatch day is out of the question. And how should I fix it, I never knew so well, because the Velcro is use a little odd (you have the bracelet buckle, so that the Velcro comes on to the counterpart, which is generally rather unstable and comfortable wearing not promote).
So the device was soon back again. A little thought-out design and poor functionality - that describes this product probably best.
