I purchased the Energizer 379 battery to replace the Renata 379 battery that was originally installed by the watch manufacturer in two of my daughter's Fossil watches (model numbers ES-9525 and ES-1001). I also replaced the Energizer 379 battery (I do not think Energizer was initially installed by the manufacturer) in my daughter's Relic model number ZR33503 watch with a fresh Energizer 379 battery. The energizer battery has a three (3) year shelf life based on the date of manufacturer. The two-position manufacturer date (usually alpha characters) is printed on the packaging. You can call Energizer Customer Service at 800-383-7323, M-F, 7:00AM-6:OOPM CST and they will give you the month and year the battery was manufactured based on the two-position code you give them. For example, code "JC" meant the batteries I received in January 2011 were manufactured in October 2010. Manufacturer Codes are randomly assigned so you must call Energizer for the battery manufacture date. Tip: To preserve battery life, disengage the battery by pulling out the watch stem when watch is not in use. NOTE for Fossil watch owners: After speaking with a Fossil watch service center, I decided to replace the battery in my daughter's Fossil watches rather than paying $10.00 to have a service center do it. Granted, it may void the warranty. And, the back cover gasket may not seal/re-seal as well as it would if the Fossil service center were to perform the task, but I feel it will seal well enough to provide many more years of satisfactory service. Keep the "original" battery and re-install it in the watch if you must send it to Fossil for warranty repair. There are some Fossil watches such model number ES-9825 that you can not easily remove the back cover and battery replacement must be performed by a Fossil service center.

and these arrived just as advertised. Beats the $4 to $5 each at Walmart or jewelry store to have your battery changed

I checked many stores before going to Amazon.com to search for this battery. At Amazon.com, I was able to purchase a pack of 5 batteries for less than the price that I typically pay for 1 battery for other watch batteries, in stores. They arrived very quickly too!

The product was very ecomomical and they performed the way the product was advertised. I would recommend this product and Amazon.com for future purchases.

Good brand, fast delivery and sharp price. Was able to put a new battery in my wife's watch and get four spares, all much cheaper than taking it to a jeweler.

There was a problem with delivery, was re-delivered after multiple email exchanges with the seller.

Initially, seller provided a Tracking number, but did not indicate that one has to go to endica.com to use the tracking number. Also, the initial link provided to endica.com did not work.

Batteries look good for now, but it is too early to tell how good they are.

Need to wait and see if they work for at least a year.

The SR521sw batteries were received as promised under one week after placing the order. Will definitely buy from the seller in future. This battery was used to replace the original one installed by Seiko without any problem. The watch is keeping time accurately after about two months of installation.

BOUGHT THESE BATTERIES FOR ONE OF MY PHILLIP STARCK WATCHES. FOR THE QUANTITY AND PRICE YOU CAN'T BE THE DEAL, AND THEY ARE ENERGIZER BATTERIES, SO YOU CAN NOT GO WRONG.

This vendor went above and beyond to try and satisfy me.

They were courteous, friendly, knowledgable and

filled my order with a timely precision.

Thanks.......

Why pay eight to ten dollars to have your watch battery replaced at the mall when you can purchase an five pack of batteries from Amazon for much less and do the job yourself? The batteries arrived quickly and worked like a champ. My wifes watch is working again and I have some extra coin in my pocket.
