Most likely that 212 from King is the sapphire crystal version (probably without AR coating), the same watch that Paul is selling @229 USD.
That watch (apart from the other well known flaws) has incorrect subdial hands: metal rather than black.
Joshua's version has correct black subdial hands, but its crystal is mineral glass, not sapphire. Not necessarily a defect, as domed sapphire crystals proved quite prone to explode. After a peer review of all the available options, I recently ordered exactly that watch from Joshua.
If you are a fan of sapphire, Andrew used to have an Asian 212 with black subdial hands and AR coated sapphire crystal @308 USD. But I suppose it is sold out now, as he removed it from his list. You may still try asking him or Josh.
Should they prove unable to provide you with that watch, you may still find it also from dealers not accredited on RWG, e.g.:

Price is very high, but that dealer makes huge discounts for repeated customers. If you are interested, drop me a PM and I'll try to introduce you to him in hope to get a discount for you.
In any case, please consider that I choosed the 198 USD version from Josh in the end.
BTW, welcome to the forum, it might be nice to introduce yourself in the proper section before starting asking question, and it would even be nicer to say 'thanks' to those who gave you their answers, like in: http://www.rwg.cc/members/index.php?showtopic=39230
