I would say always buy the seller! David SW, Takua, and Tony are all extremely reputable...so your next question is whom is going to give you the best deal for the newest condition watch and accessories? That said, I've done many deals with Tony of SD Watches and they've all gone smooth! It is my understanding that Tony has a Brand New White Ceramic w/ all accessories for $17.5k. If that's true, than seems the price is right under the current circumstances!
