Renata Silver Oxide Watch Battery 371 - SR920SW (10 Batteries) …

Was paying a HUGE fee in the brick battery store locally to install one of these into my Tourneau $5,000 dollar watch, and they petered out way to fast.Got a pack of these and a cheap but adequate watch battery install kit and do it myself. THIS battery, my first one I tried, is STILL working long after the brick store one would have, and did, quit.

Very good

Good battery life so far.

I collect and restore 19th century mechanical pocket watches. I also work on modern quartz items as well. I keep quite an inventory of batteries as a result; purchased in bulk. I have found, thru experience, that some manufacturers batteries simply do not last as long as advertised. Having used Swiss-made Renata Silver Oxide batteries in the past, I find their quality and battery life to be superior. Cost slightly more = Yes...but. My customers deserve to know they won't be changing batteries so often.

Fast shipping and works great.

works good

Used these in Hearing aids and they lasted longer than any other. Using in watches has shown the same results.
