Thanks to this battery and others that I got from the same seller, I successfully replaced the batteries of three wrist watches (Skagen for men, Nexxen, and Ann Klein for women).I had my doubts about replacing the batteries by myself after reading on line that you may need special tools to replace the batteries of a watch, but I used the little screwdriver from an cheap glass repair kit to open the back of the watches and then replace the back with pressure from my fingers without any special tool.I also was concerned with the life of the batteries, but they are working fine.The seller (Best Deal Supply) was great with fast and efficient delivery.Final results: I have three working watches replacing the batteries for just a couple of dollars.
