Can't decide between these. I'm a serial flipper with an average hold length of about 6 months. I'm hoping whatever I get next will last me 10 years (but realistically more like at least one year). I like the lighter weight of the Rolexes (due to the different steel they use). Love the look of the Explorer. But GS Quartz is so much beauty for for about $1600. And GS Auto seems like a reasonable compromise. Please help. Thanks!
