I would go for the Lange 1 mp..
I kinda like the mp plus day-nite indicator.. but suggest that you try all watches in the metal.. some say the new mp could look abit boring in the day, I m not sure..
Personally I find the 1815 annual cal aesthetically too busy..
But it's curious that both annual calendars do not have day-nite indicators since it's a useful function for calendar complications.. not sure why this is the case..
