Well, the Renata batteries that came with my watch were perfectly good, but I wanted to install a fresh set just the same. I purchased a “fresh” set of Renatas from ebay seller 1111deals in Brooklyn, NY and they seemed fine, so I mistakenly left positive feedback when, in retrospect, I should have demanded a full refund. It’s only been about 3 days and today I went to do an early daylight savings time adjustment and noticed that the display was very dim. I reverted back to the Renatas that the watch came with and everything is fine again.
No wonder the price was so low.
If you need batteries here in the US, I would highly recommend ebay seller beachs_best_batterys. He doesn’t sell Renatas, but I’ve purchased plenty of silver oxide Energizers from him at very low cost, and they’re always factory fresh and last a very long time.

Happy Collecting!
