If Annie has a Apple Watch,

and she eats it, will she die?

The Apple Watch is water-resistant, not water-proof. Prolonged immersion in any fluid may lead to permanent damage.

Considering the acidity of your gastric fluids, stainless steel may be marred or discolored. Aluminum shouldn't be damaged - acid is used to clean aluminum. 18k gold can be disolved in very strong acids, however, I don't think your stomach acid will do the trick (not sure on that, let me know if you swallow the $17,000 model). The various glasses should not be affected.

Since the Apple Watch is not intended to be consumed, you would invalidate your warranty.

The 38 mm Apple Watch is 38.6mm high, 33.3mm wide, and 10.5mm deep. Your esophagus is about 2 cm in diameter, which should prohibit you from actually swallowing the Watch. Your small intestines are about 2.5 cm, which would also preclude you from retrieving your watch without surgery.
