This thing is freaking huge, but it is all battery life. lol. Example would be, I didn’t charge my watch but twice in the last 30 days, and my spouse has the 43mm version, MK3i too, and charge theirs once a week. What a noob. The watch itself, in regards to design and functionality…Garmin needs to try a little harder. I get not being a smartwatch and all, but it is basically my 6th grade Casio, but I can be down in 125 feet with it. So, that would be a cool thing to do, change the Casio from degrees to radian mode at 125 feet underwater. They say dreams don’t come true. Haha. But, anyway, this is a pretty freaking sweet watch! But, I still use my Perdix 2 as my main, sorry Garmin, you’re cute and all, but if I cannot do a constant connection with my phone, standing next to it, I can’t trust the air numbers, and I’ll have to use my manual, backup, Stone Age Pressure Gauge, in the pitch black, with the alligator gar lurking around. Haha. So, yes, 5 stars for awesome, 2 stars if it was the 43mm, and it’s mostly for battery life, and the people who sold it to me. They’re cool too!
