I was very impressed with this watch press. I used the press to insert a new crystal into my watch and this watch press did a great job apply even pressure to the crystal so it sits flush within the case. I have used other presses in the past with handles and leavers and I found that since the leaver acts as a fulcrum the pressure is not even and it leaves the crystal sitting at an angle. This is especially a concern if you are pressing a domed crystal which has a tendency to be extra difficult to sit flat. The material of the instrument is also very sturdy and heavy duty and I can see it lasting for years without encountering mechanical issues.
