Second, one can be an analog watch aficionado AND fascinated/converted to a digital watch like the Apple Watch.
You don't suddenly become a "gadget guy" just because you've stopped wearing the analog watches in your collection in favor of something more practical.
If non-fashion, non-mass market brands targeted at the mid and high tiers of in-house haute horlogerie don't constitute "real watches" for you, what does? Your comment reads like I mentioned the widely recognizable "status" brands like Rolex and Tag Heuer. Nomos (entry-mid) and Lange (high-ultra high) are two of the most well-respected watch houses in the world right now, and probably the most well-respected from Germany (as opposed to Switzerland).
You're right that I'm a "gadget guy", though. I just appreciate both, and my original point is the Apple Watch's raw utility is capable of displacing my passion for mechanical timepieces and their craftsmanship.
Having said this, I am not disputing that he is a watch guy. I believe he is because he says so. As far as I am concerned this is enough.
1. I'm what you'd call a "watch guy." In the time I have had the Apple Watch Series 2, I have barely used my mechanicals (including a Lange & Sohne and a Nomos Glashutte). The Apple Watch comes with me on all but the most formal/elegant occasions, and I now hate changing straps on my mechanical watches in comparison. The Apple Watch may not be as beautiful, but it is far more versatile and useful. When I want to dress it up a bit, I throw a Hermes leather strap on it, which works nicely in just about everything other than a suit (which is essentially the only time I'd jump back to the Lange).
2. You're vastly underestimating the utility of quick replies on the Apple Watch, in particular. I have quick replies for every conceivable response I could give to someone that is fewer than five words or so. This makes a lot of communication much faster because I don't need to take out my phone - I can tap, "congratulations", "cool!", "no", "yes", "I'm in a meeting", "I'm in a movie", etc.
3. Having notifications or synced functionality on the watch is a very frictionless way of enhancing iPhone interaction. As other commenters have said I can quickly glance at a multitude of things, not just the time. If I receive a message on Slack, I don't need to take my phone out if it's not something that requires my attention. When driving, I can have directions on my wrist directly, instead of on my dashboard. I can even have conversations on my wrist, hands free, while cooking. These are all ways it's directly enhanced my life in ways I wouldn't have really thought of without trying it.
4. I run a fair amount - at least 30 miles each week. The Apple Watch is the single most empowering device I've ever had for quantified self tracking and fitness enhancement. Having a pair of Airpods and an Apple Watch is a fantastic combination - I can't even imagine bringing my phone with my on a run anymore. I can look at my wrist to see my pace and split information, and that's just on the native Workout app. I can track my heart rate constantly using something like Cardiogram. I can also track my sleep. There is a massive amount of data enablement that I can now see and monitor as much as I want in the Health app.
