My water-resistant watches with user replaceable batteries beg to differ. I bet the margin wouldn't be as high but it would certainly be doable from an engineering point of view.

Just curious, which watch(es) do you have?

  I don't know about OP, but as far is I know every "non-smart" watch that is waterproof has a replaceable and standard sized battery. Normally, you also have to replace the o-ring, which are also pretty standard.
