I would go with the SRPD65. This is based on your request for watches that watch enthusiasts will care more about even though 99.9% of people are not watch enthusiasts. You would be more than fine with either of these though.
-For people in the know, automatic movements get more respect than quartz. It shouldn’t matter, but he will get a little more street cred.
-The “SKX style” is pretty famous among watch people. It’s also just easier to read.
-Depending on how big his wrist is the other watch might be a little too big, but I have a pretty strong preference for smaller watches so that could just be my bias talking.
To be fair, the Moonswatch was an industry changing event. Although I think you’re right. I didn’t know anything about Blancpain and the prices are high enough that anyone in the swatch price bracket is not even close to being in the Blancpain price bracket. Omega was a big price jump but nowhere near as big of a jump.
