First let me mention I have absolutely no experience repairing Apple Watches, so don't consider me an expert!

That said, the material I would choose for this job would be a light and flexible epoxy such as Zhanlida B7000. We use this quite often for sealing camera lenses on iPhones as well as replacing any failed adhesive between the cover glass and the plastic frame on any model of iPhone screen. It is durable, water resistant when applied correctly to properly cleaned surface, and any excess adhesive that leaks of the water can be scrapes away by you fingernail if you just let it dry for 10 minutes. Manufacturer recommended curing time would be 24 hours, but it would reach 90 strength it you give it 4-6 hours. The device should be very lightly and even clamps during this time.
