Durable, long life
Make sure you buy the right battery type for you watch (or other item). In a good quality watch this battery can last more than 3-4 years continuously working.

Good watch batteries at keen price
Can't really judge the "longevity" issue yet as these are for a watch whose previous batteries had died and I've only just changed them. Supposedly should last for 5 years; they are an "odd" size that Poundland etc do not stock.

"Tick Tock" said the passage of time "B*&$£x" replied humankind
Watch decided to die on me in bed. I've never seen 04:19 once then woken later to see 04:19 again and think ahhhhh another 7 hours before I have to get up and ring in sick. I had to actually get out of bed faster than normal which is extremely uncomfortable and should be avoided at all costs and check a clock in the landing. Which at the time said the correct time of 07:11...urgh still time to get to work on time...disappointed. So before ordering this battery I requested the seller send me an out of date one in the hope this occurrence well re-occurred and I could actually be late.

Simple working battery
Works so far, have minimum expectation that it works for a year. Last renata battery lasted over 5 years. I will update if battery life of this sony battery is less than a year.No prime delivery, but still very fast first class postage in an envelope. Very happy.

Watch batteries for G Shock watch
I bought these batteries for my G-Shock watch and they fitted perfectly as I expected - longevity review will have to wait but should last a minimum 2/3 yrs hopefully. The price offered good value for money and delivery was free and fast.

I saved nearly £50
Not essentially a review of the product although it does the job of powering my watch. When I went into a couple of shops they said it would cost around £50 to replace the batteries in my Casio "Twin sensor"; the watch only cost £60. Two of these batteries cost under £3 and You Tube has a number of excellent videos to show how to replace the batteries yourself. It is fiddly but not difficult.
