Apple Watch SE 2 - water resistance
I've just bought an Apple Watch SE 2, and I have read that it's water resistant to 50m, but I also see that it has a water lock. I am reading contradictory advice as to whether I need to set the water lock before showering or swimming - or whether the watch is already water resistant and I don't need to set the water lock?
I am used to having a water resistant watch and so don't think I'll remember to turn on the water lock!
Thanks for your advice.
