## Description

original sony

Review: Huge cost savings - Replacing a battery can easily cost £7-£10. With this 5 piece pack, you can save a lot of quid. And by the way, these are the actual batteries which Fossil watch use / company fitted. The delivery was also quick and no complaints with the quality.
Review: Cheap Watch Batteries - What I needed for my watch at an excellent price. Bit of a fiddle to fit but my old watch is now going again at a fraction of the cost of going to jeweller. Only time will tell how long they last but it should be a while before I use up the whole pack!

## Questions & Answers

**Q: Is this battery silver oxide?**
A: SR means Silver Oxide

**Q: does this replace a 621 battery?**
A: If you have an SR621 battery, Yes it does.  But not a brand name designater 621. You MUST be careful with only replacing SR621 with SR621. Check your old battery first.

**Q: Is the 5 pack 5 batteries or 25 batteries? It say multiple places there are 5 batteries per pack.**
A: It is 5 batteries....not 5 packs of 5 ea....you can also buy a 10 pack which is just 10 batteries in the pack. Each battery has it's own blister pack and they are all attached, so you just tear each single battery pack along the dotted line to separate one at a time so the rest stay sealed. Hope that helps....

**Q: does this replace the 321 watch battery?**
A: I don't think so. It would be a 364. (the 621)   Sorry

### ⭐⭐⭐⭐⭐ Cheap Watch Batteries
*by F***O on 10 April 2016*

What I needed for my watch at an excellent price. Bit of a fiddle to fit but my old watch is now going again at a fraction of the cost of going to jeweller. Only time will tell how long they last but it should be a while before I use up the whole pack!

### ⭐⭐⭐⭐ Highly cost effective
*by B***E on 7 September 2016*

Works fine. First battery lasted almost exactly 6 months, about half the life of the original battery, but still much cheaper than going to a jeweller and it only took a couple of minutes to replace. I would strongly recommend getting a watch back press if your watch has a snap on/off back.
