Renata 321 2-Pack Watch Batteries - Long-Lasting Power for Watches, Clocks & Small Electronics - Perfect Replacement for Timex, Casio & More

The batteries are good the ones. Got two of them for different watches. Two year date on them so in they went and the watches were off and running. Tested the voltage and the were up to snuff.I bought a battery at a jewelry store that cost $14.99. I told them what type of watch it was and they sold me the battery. I checked on Amazon and they had the recommended replacement battery brand for my watch, for 1/10th of the cost of the jewelry store battery. Needless to say, I returned the unopened battery to the jewelry store and my watch is keeping time as it should. Thank you Amazon!Bought a two pack. First battery was dead. Second one worked.Used it on watches, satisfied with product and service.Love this battery. The circled edges are so smooth and I love the way it looks sitting in my watch. I almost hated to put the back cover on.Watch battery replacementThese batteries plus a $7 watch repair kit saved me from spending $60 at the local watch repair shop-the same shop that only charged me $15.99 fourteen months earlier. Shop claimed it needed a "special Swiss battery" (which this is) and "the expertise to avoid causing damage that could wind up costing you $150".These batteries are the exact same brand & model number as the dead one that I removed from my Accutron watch, plus I have 2 spare batteries for future use.I did it myself in 10 minutes and it's running like a champ. I am a 65-year-old female.The batteries work great and they got them to me quickly. Needed different battery for another watch and ordered from this seller specifically because of service. Whether or not they are fresh and work as long as they should (about 1 year) is something to be determined.
