## Customer Reviews

### ⭐⭐⭐⭐ Quality watch Batteries
*by D***E on 12 August 2024*

SR616SW Watch Batteries - 2 x Seizaiken 321 Equivalent Cell Button WatchBattery Replacement Kit for Watches with Fitting GuideThese batteries are actually made by Seiko as can be seen in the description. I cannot test for longevity compare to Renata / Maxell et all. However, if I find a short life in the battery I fitted to one of my spare watches fails early, I will update this review. There is not a lot more to say, its just a battery and fits well.

### ⭐⭐⭐⭐⭐ Made by Seiko so the quality is great
*by P***A on 5 July 2024*

Seizaiken batteries are made by Seiko so you know that the quality is going to be excellent. You also expect the price to be higher too - and it is - but these batteries should last longer than cheaper brands.I haven't needed to fit these yet but having used Seizaiken batteries before I am ceratin that they will be fine and keep going for a long time. It's also tricky to review a battery that might last 3 or more years, but if these batteries do fail within a shorter time than expected, I will update this review.
