I fairly recently bought a version 2 Apple Watch. It is waterproof to something like 30'. Version 1 is water resistant which is why I went with version 2.
I like it and, not fishing related, it has focused me on getting some exercise and focus on what I eat.
I just read version 3 will be out soon. The one thing the article said was added is LTE capability. I was wondering if that means you need another cellular provider contract! But it may mean a price drop in the version 2.
Hope this helps, PM me if you have any questions.
