The timer is very well done by design. It looks very classy, far more expensive than it actually is. One has to raise him up to the stop and then turn back to the desired time. He works well. However, it is not accurate to the minute. In my experience, you have to tolerate differences of about 2-5 minutes. Who is sufficient for these timepieces is the right one. When it comes down to the minute, then you should choose another. Since I need the timer for times between 1 to 2 hours, I can live with this uncertainty. In the range of 1 to 5 minutes, so at very short time intervals, it is very difficult or impossible to set a time. In conclusion we can say that it is a very beautiful and rugged timepiece with an existing, but quite tolerable inaccuracy.
