I decided to buy this tool to open a watch that has a screw cap. They asked me 8 euros in jewels supermarkets to replace the battery and I have never met a friendly saleswoman who wanted to just open the watch, without selling me the battery (only 2 euros in the store shelf). I do not regret this purchase, I opened the show in less than a minute. The tool works very well, he is very good and very fast. Besides the satisfaction of no longer enrich unkind traders and profiteers!
