Some functions include, but are not limited to, a monopusher split-second chronograph (no idea how that is done with one button), a 1000 year calendar, very accurate equation of time (between solar and clock time), complex sonnerie chiming functions, multiple timezones, moon phase indicator, and of course, more. The obvious competitor to the Aeternitas Mega 4 watch is the recently released Jaeger-LeCoultre Hybris Mechanica Grande Sonnerie watch. While the Hybris Mechanica only has 25 complications, it is arguably more pleasing to the eyes. Plus, for a bit less price you get three watches and a fancy safe.

The Franck Muller Aeternitas 4 watch is the high horology equivalent of a fancy Texas Instruments graphing calculator. Sure it does a lot and it gets us mechanical nerds excited, but it isn’t going to get you any action from the ladies (but sharing with them the price tag of $2.7 million might).
