I’ve long loved my PRW 1300t-7v. It’s gorgeous but it lacks the version 3 sensor cluster. My 3100 has that but it’s a negative display and basically everything on it is black. The band is comfortable but it’s not metal. I like metal.
Best of both worlds… the PRW 3500t-7v. Looks a bit like my 1300 but with the vastly improved sensors. Sunset and sunrise a plus. Welcome home friend.
