Apple Watch Ultra 49mm cases

Ultra, Ultra 2 and Ultra 3 take 49mm cases. A Series 10/11 46mm case won’t fit. Pick by job: open bumper, or hard case with glass.

How these picks work

We choose from Amazon listings, product specs and public ratings, not hands-on testing. Ratings shown are Amazon’s. Check the size and current price on the listing before you buy.

Bumper (no glass)

A bumper guards the titanium edges and leaves the screen open, so touch feels unchanged.

Hard case with glass

These cover the screen too. Expect a slightly different touch feel.

Size check

Ultra cases are 49mm only. Ocean, Alpine and Trail Loops are made for Ultra; regular 44mm to 46mm bands fit too (Apple size guide). For Series cases, see clear cases or the cases hub.

How buying works

We may earn a commission when you buy through retailer links, at no extra cost to you. See the affiliate disclosure.

None of these cases make the watch waterproof. A case with glass can trap moisture, so remove it after swimming and let both dry.

How we pick products

  • We shortlist accessories from Amazon listings.
  • We check each listing’s stated Apple Watch model and size compatibility before including it.
  • We compare listed materials, features and price, and we use Amazon’s public star ratings and review counts as one signal, not a verdict.
  • Our coverage is research-led, based on listings, specs and public ratings, not hands-on testing.
