Breguet

So time to read up! ...  

Thanks for sharing, it's beautiful.

There are a few makers that took a shot at doing a perpetual calendar in a line, and I got to say the cleanliness of this one is really appealing to me Glad you like it, it deserves love

Gotta say I like the Type XX 3803 - my size and it ties back to the aircraft instrument and has that pear shaped crown (And no date window!) ...  

You do NOT need to think past this! There's nothing in the Type XX line that comes close (and I say that as a very satisfied owner of one).
