How about this IWC Grande Complication ? You get perpetual calendar all the way to year 2499, moon-phase, chronograph and even a 21-second mechanical alarm !
ok. this is something I really can't stand. Grand complication watches I run far, far away.
First and foremost, where got money.
But secondly so much maintenance. You got to keep that thing on watchwinder forever right?
Thirdly and very applicable to a lot of people is I can't stand weight. I love mechanical but I can't stand weight so that's why I have a thing for earlier rolexes before they became bloated.
But I don't mind admiring it...
