The replacement battery kit came with two gaskets/spacers with adhesive. But the adhesive (pre-applied to gasket) was useless - not very sticky. The watch would not stay together. Heating the watch and pressing it together was no help.
What did work was to clean the gasket and watch faces with some 99% isopropyl alcohol, then use B-7000 multi-purpose adhesive as mentioned above. Let it set for 24 hours with clamping pressure applied to watch. I've worn the watch for 5 days so far and keep checking to see if the face is loosening up. So far no problems.
