Yeah.
My (<2 yr old) series 6 watch now has water damage to the face and digitizer, after doing a swimming workout. It's nominally 50m water resistant, and I went a max of 1.5m. It's had a handful of water experiences, but nothing deeper than a pool and no high speed/pressure type stuff.
It's effectively dead.
Apple wants 359 eur to repair it. The new cost, with charger (39eur) and the braided sport band (100eur) ((which was nice, but stretched and became useless) was 509 eur. So there's effectively a 10 eur difference between the original sale price and the repair price.
There are refurb series 6 gps + cell on the amazon.de for 299 eur, and those include a strap and charger, as well as the cell functionality that I didn't have.
This is within the EU (and Ireland) 2 year limit on defective products, and I originally bought this from Apple directly. So I might have a claim there. On the other hand, I don't want them deleting my apple account in retaliation.
