My bro is now slightly afflicted by the rep bug and wants to get a good Cartier Tank in stainless for his wife. As I understand it, most of the GEN tanks are actually quartz (the larger models are autos), so a quartz model would be ok. Has anybody purchased one that they were impressed by? He wants the no frills model - stainless only, no chronos, no diamonds, no blingedy bling bling. Thanks!
