Re 47 mm Pams, the short answer is to just go out and get a Noob 127 (if you can find one in stock!). Superb quality, the 217 is another option from same maker.
Other 47 mm to check out (with lower quality) are 203, 306, 372 (luminors), 187, 193, 194, 305, 382 (submersibles) or 232, 249, 294, 309, 322, 339, 349, 373, 376, 379, 425 (radiomirs). Good luck with the search mate, can also advice on the IWC Big pilots (5002 or 5004), bought one a couple of months ago and love it!
