Welcome to the forum. Yes the reference 212.30.41.20.03.001 is a glossy blue new Ceramic version. Really nice model i must say
Yes that ref number is only for one blue watch with 41m case. What is the warranty that the Amazon seller is offering for the watch ? Probably he is a grey market dealer meaning that he has "in house" warranty and not Official Omega Warranty. If anything happens to the watch you will have to send it to USA for being serviced. It will be serviced not by Omega watchmaker. Just keep it in mind. I would choose to buy from one of the watch forums from trusted sellers. You can check out what's on sale now here:
