I swim in place using a tether and like to use one and two minute timed intervals for different strokes. Is it possible to create a workout like this using the Apple Watch so that I know when an interval is done and it’s time to start the next one? Also, are there recommended headphones to use while swimming?
Perhaps not quite what you envision, but some of the workouts, such as HIIT, allow segments to be marked. See here for further details:

There might be third party apps providing more such capabilities in this area. Best to check the App Store.
You could also suggest adding enhanced support for the intervals in the future releases:
