Amazon Customer –
Perfect replacement for old watch
Used this to change an old Sony battery on a friends watch. It worked perfectly and saved a lot of money by changing it ourselves. I got 2 orange ones that have a expiration date until 05/2027 and blue one that expires on 08/2026, so I guess the orange ones are the “newer” models.Anyway very happy with my purchase and I recommend it to anyone that want to change the little batteries of their watches themselves.
