Let me start by saying that the tool worked great.  I replaced batteries in two of my wife's watches (one Burberry and one no brand one).  In the past I always struggled to close these watches' backs, but with the SE Watch Repair Tools Case Press it was very very very easy.

Since modern watches are of larger sizes with larger crystals, I installed the larger rubber cap on the fixed part of the tool.  I then selected a die whose diameter was closest to the diameter of the watch case lid.  I placed the watch crystal down on the rubber cap, aligned the lid, and squeezed the tool gently.  Backs of both watches popped right in with a relatively light squeeze of the tool.  It is amazing how easy it was to close these watches with the proper tool compared to the prior times when I struggled sweating and getting frustrated trying to close them by hand.

My watch case press came with a plastic storage box (although the item description said the box was not included), which is a nice feature.  The distance between the die and the rubber cap is more than sufficient to accommodate the fattest watch I have (5/8").  The gap can be adjusted to accommodate fatter or thinner watches by turning the screw in the fixed part of the tool.

I would have rated the press 5 stars if not for the following: 1. No instructions included (thanks to other reviewers explaining how to use the tool), 2. Both rubber caps are significantly smaller than the crystal on modern watches.  I wish there were a few larger size caps included to spread the pressure better on larger crystals.  However, I used the bigger one and had no problems. 3. I wish a couple of larger sized dies were included to better fit lids of larger modern watches. Again, I had no problems with included dies.  4. The tool is painted blue and the paint was scratched and chipped right out of the box, as if the tool was sitting in a container with other metal tools before being packaged.

Overall, I think this is a good addition to my arsenal of watch repair tools.
