The new ST case will work with the clone 3135 but like you guys said, the rehaut is deeper. If you find an older ST case for the 3035, it will have the shallower rehaut but the 3135 stem won’t line up. A good case if you can find one is the old “Noobmariner” 16610 as they have a nice shallow rehaut. For my 16800 I used a JF v1 and shaved off the rehaut engraving and it’s a bit shallow like you want and still takes the 3135. You need to upgrade the bezel assembly though becasuse it’s junk. I don’t have an old noobmariner anymore but from what I remember it would be perfect for a 16800.
