A short time ago, my day to day watch battery ran down, so I put it in the pile with all of the other watches with flat batteries. "I really must get it fixed", I was thinking as I wound a trusty analogue watch as a replacement.
The previous time, I ended up buying an inexpensive watch because I was stranded somewhere 'in transit' and when I did eventually get it fixed, the jewellers wanted to charge me a large number of guineas.
So this time I spotted the rack in a store with the tiny batteries. "Easy", I thought, as I looked at all the bubble packs with little pictures of watches on them. But at £1.29, I decided to take a few different sizes of Golden Power Super Silver Oxide, thinking I'd get one to fix my watch and if I was really lucky I'd also be able use the surplus in other defunct watches.
One Swiss Army knife later I'd opened the silent watch and did manage to locate a battery half the thickness of the dead one, which has made the watch go again. But none of the other four will actually fit any of the other broken watches. I'm still 'quids in' compared with the cufflinkeried jewellers, but also slightly annoyed that there's so many different sizes. And that's before I noticed that Amazon sell ten watch batteries for £1.99.
