2 and 5 in my view are two of the most incredible pieces ever made. 2 for all seasons and occasions and 5 for dress. Timeless classic and elegant all rolled into one or actually two. While I own the 372 and love it, the 232 is probably my favorite piece. If it had a domed plexi, would be perfect, but with the more flat sapphire it's still an incredible watch. Again what an incredible collection you have oozing DNA and beauty.
The luminor case shape is probably more recognizable as "Panerai", and therefore earns iconic status. However, the radiomir has every bit as much history, and arguably even more brand DNA.
Both are great!
