If you're in the market for a smart watch, and you're a cyclist, I'd recommend checking out Garmin. They have a massive array of sensors and record very precise data that is aggregated on Garmin Connect. It's been invaluable to me for assessing training effectiveness over time. They make Apple watches look like toys. If you want the latest and greatest, the Forerunner 945 is probably what you're looking for, but the older models can be found for cheap and are still solid watches. If you want emergency alerts, you'll have to stick with newer models though.
