I'm so surprised that these other high end brands haven't followed after GO at all. I can understand this - since the average consumer isn't looking for planetary gears that allow torque to be consistent to the mechanism during the few moments you're winding the watch. And very few clients are asking for hacking seconds - much less a zero-reset and minute detents. I'd say most Patek Philippe watches on sale today are just starting to get hacking seconds as they've only recently fully switched from the 324 caliber to the new 330 caliber. C'mon Patek! Vacheron!
