The jeweler said my watch was broken and wasn't worth fixing. I put in the Renata battery and Voila! the watch is running again.Replaced in my key fob, has worked great for a year!These little batteries are amazing technology. What more can you say.Well, the products that used them could be designed in such a way that, it is easier to remove and replace them!Alternatively, the battery designers could add a small tab to the battery (permanent) that makes placing and pulling them easier.or a battery loading tool of some kind…Also, recycling these things is a big pain. More places should take these small batteries back besides Radio Shack.Maybe Amazon could INCLUDE a PP return envelope with EVERY button battery it sells!I have a Victorinox watch with the date feature. Nothing special. This battery lasted about 21 months. I expected longer life and will look for it from Energizer or Duracell brand batteries. Battery was inexpensive and didn't leak in the watch, so it isn't all bad. Just want one that lasts longer.Exactly as advertised...hope it lasts as long as the last one.Arrived in a timely manner and was just what I needed. Good price!cool!unfortunately, it was not the old renata battery's problem, but my wenger watch. since the watch only lasted 5 years, bought a $44 Timex Expedition as it cost about the same as all the postage, etc, to send it to Wenger and back, plus the large minimum charge to even get an estimate for the cost of repairs needed.
