The value is good. There is one caveat, however: The needles of the mechanism are not interchangeable with those of Kienzle mechanism that I changed. So I used the needles supplied with the mechanism, much too long that I had to cut. But considering the form of needles, needle remaining hours is really too thin. The needles are gold, and I had to color the black felt, because they were just visible on my orange dial. I had to cut off the ear attachment that bothered. My suggestion is that it would be good to make the choice for the length of the needles and color. To cut the ear I just was pointing to a potential problem that may exist. If the mechanism works well, it's quiet and precise.
