Hi Brian,Thanks for reading my blog and yes, wtechas are pretty addictive.Swiss are definitely worth the extra buck just make sure you buy from reputable websites and not get scammed as the Swiss scam is kinda the new black in the replica wtechas world meaning that you pay for Swiss and not get Swiss.As for the crystal you have to take a good look first and then ask them what kind of crystals their wtechas have.Let me know what websites you're interested in buying from and I'll take a look.Thanks,James
