Rolex Air-King

The Air-King was originally created to honor the RAF pilots of WWII, and the "Air-King" text remains one of the few remaining "original" fonts on Rolex dials today. It's interesting to see this alongside the Panerai PAM 372 you shared again—they represent two very different ends of the size spectrum, from the massive 47mm Italian naval diver to the discreet 34mm British pilot's tribute.
