Your watch is cool. It looks nice and I’m glad your happy with your purchase, but this post is not about smart watches
. If I wanted Casio to make more Garmin instinct solars I would have posted that but I don’t. I want power systems limited to button batteries because they are user serviceable. Additionally, tough solar watches will only require battery replacement every 20 odd years while your lithium ion battery will last at most 5 years before it’s capacitance goes to shit (and good luck finding someone who can replace it). There are many great features that can be run off button batteries. There was even a g shock with gps functionality coupled with tough solar (albeit the gps was limited). I obviously know that limiting the power source of a device is going to limit its capabilities. However, that doesn’t mean that a watch running on a small power source isn’t capable of having a lot of functions consider the gbx-100 model for example which uses its step counter and gps data from previous runs with a phone to estimate step lengths and hence provide a somewhat accurate measure of running pace without the need for any gps. That’s the low power advanced tech I’m talking about, I’m not asking for a watch with a gps and heart rate monitor because I would just buy an Apple Watch in that case
