To be honest, the Apple watch isn't even in the same class as this watch. This is the kind of watch that people who are going to be traveling into the deep wilderness will wear instead of three other gadgets. It has a maximum battery life of 8 days, depth gauge, altimiter, barometer and a satellite communications module.
Edit: This would make a great watch for sailors to supplement an EPIRB.
Yeah, that's Garmin's thing. They are selling top of the line, marine/aviation grade, safety critical equipment. $2,000 is almost low for what they normally sell, like radar systems and chart plotters for boats, or glass cockpits for aircraft. They are mostly competing with Raytheon and BAE systems for niche applications. Stuff you would find in F-16 fighter jets except better somehow.
Essentially, Garmin is the product you buy when money is no object. Either because you are obscenely wealthy, or because you are trusting their product with your life and the lives of your passengers. They have some consumer grade stuff too that is usually trickling down from their obscenely expensive other businesses.
