Trusted brandDuracell is a recognized name for decades. It's easy to find the size and really it's a coin toss as to which kind of a battery manufacturer you go with and what's your expectation and use are for them. What I've learned has been a majority rule is that brand name batteries when their end of life and compromising don't corrode or breach their packaging as badWorked in the Seiko watch. It will be two or so years to judge longevity, however expect no problems as it's not brand-x.Item was of the most fab quality. Superior packaging. Delivery was excellent. Exceptionally pleased.Does what it is supposed to do.Bought these a little over a year ago and my watch just died. The original batteries in my watch lasted over 3 years. Not sure why they died already. I've done nothing different with my watch usage.It’s a battery not much more to say. It fit my application, a watch and works fine.Will buy again if needed.
