I bought a 31 DJ with diamond bezel and MOP diamond dial. My two Rolex gens were both 28s. It took me a moment to get used to the 31 but I love it. I bought mine from Puretime, who I highly recommend. Next up is a Cartier tank. I have a small wrist and worried it would be too big, not interested in the "boyfriend" thing at my age, but it's just right. I'd look at 31's. The selection will be larger and the quality better.
