In trying to determine if the new Apple Watch 2 it might meet my aquatic needs, I’ve found Apple’s marketing and support pages largely devoid of detailed information. Fortunately, I’ve been able to turn up Apple Watch 2 details by querying a number of reviewers and via Apple Insider’s swim-centric overview. And, although Apple Watch looks to be a solid solution for those for swim continuously, my enthusiasm has been tempered:
Where the Apple Watch’s swim tracking starts to fall short is for people looking to do more varied swim workouts based around swim sets and focused exercises like stroke drills and kicking […] The Apple Watch’s pace calculation also becomes less useful if you’re doing interval-based sets, as it’s simply going to tell you the interval you were going on instead of your actual swimming pace unless you manually pause the workout as you finish each repeat and resume before starting the next one.
