Will it be another Panerai? If so, it's nice to keep the 372. I had one but sold it because I only have one room for a Panerai in my collection. I had the opportunity to get the 194 - a Panerai I have been hunting for since 2004 but never had the opportunity to snag till recent. On the other hand, like what he said, it's easy to buy a 372 back plus there's a certain coolness in a ceramic Panerai. Since owning a 47mm, I don't think I'll ever go back to 44-45mm's. Tough call, either or, you win.
