for a young sportive guy I would suggest the following:
Pilot 40MM. Slim, great look, follows the trend of Zenith right now, size is true to the original, can dress up and dress down, Pilot look is great for all watches so has a cool style. I have a small wrist, most watches are second to last hole but I still wear 44mm - 45mm.

Another option is the pilot chrono Big date. 42mm, great look, matte finish and overall a beautiful thin chrono...I personally like it on a strap but the mesh is sporty and different.

Lastly I would suggest an Espada.. It is every day watch...almost like a sub. Great size..40Mm, El Primero movement but runs like an HMS.

I also love the idea of NOS. but the worry is that unless you go much older and do classics like 3 hand autos, I think the DeLuca and rainbow for an 18 year old will look too new for an old watch with the rounder styling. Don't get me wrong, I love these watches, I have a few rainbows, some class pieces and another zenith from the same era, I just don't know if the right style for an 18 yr old.
my 2 cents
