Over the holiday I upgraded from an apple watch series 1 to the new apple watch se. I have to say I am pleased with this purchase. It was a much needed upgrade and the SE is noticeably faster than my series 1. I didn't necessarily see the need for all of the bells and whistles on the series 6 watch, but would have loved to get one. Overall the 44mm isn't that much bigger than my old 42 mm either. I was nervous about the size difference but have nothing to worry about. It's a solid upgraded and recommend this purchase.
