The new series 3 Apple Watch is probably more water resistant than the case.And as for a case, I have been using the catalyst case. Have a Spigen Tough Armor Coming and will try that next. Also have one eBay I got that is supposed to be good for bumps and scratching. Pic of the catalyst caseView attachment 36719
I Suppose to me these watches are more an investment like my phone, and I want my investment as safe as possible!!!
