Although it looks and feels well made its not. On closer inspection the watch movements that I tried in the larger of the 2 holders the movement only rests on 3 out of the 4 lips, as a result when any pressure is placed onto the movement where the 4 lip is supposed to rest the movement just pushes down and comes out of the movement holder, causing damage nor missing parts springing off of the movement being worked on. All in all these movement holders are NOT fit for purpose
Three stars for looks, other stars are waiting, cause haven't test yet. But looks fine to me.
