I have about half a dozen I love but never use. They awlays seemed to be dead by the time I got around to wearing them so I ended up always wearing this one as it's automatic:
Had it for at least 20 years. Looking for photos online it seems they still sell it but mine has a wider, straight bracelet which I prefer. It's lasted better than the other swatch watches I've had but isn't so accurate anymore and needs winding if I don't wear it every day. The performance of my other ones has put me off getting more swatches though.
Might buy a battey for one or two watches, wear them regularly until the battery goes then replace a different watch. Suppose it's stupid to save a watch for best as it never gets used that way.
