I bought this kit to revive my faithful Tag Watch. (I thought it was a dead watch after a less than honest jeweler's advice) I wanted to change the battery and see if i could extract life once again. I found the Kit very easy to use, Robust (with care) with exception to the pin extracting tool (the blue device in the image). I was able to open my watch with ease and using the precision screw driver and tweezers extract the broken screw the the jeweler had damaged whilst trying to change the battery.
Having removed the screw and replaced it with a new one the watch is working like a new one and hasn't lost a second in three weeks.
I also was able to repair the wrist band with ease using the fragile pin extractor and a couple of the included tools.
This kit saved me about 400 pounds buy repairing myself a watch that a 'specialist' wanted to charge.
Very satisfied with the overall quality and would recommend to anyone with good eyesight (small watch parts).
