Yes. The back display is incredible even to my untrained eye.
I'm leaning more towards the Breguet 5327 over the 5159. Somehow, it seems less "tiring" on my eye but that is very subjective. The Patek 5159 catches when you first look at it but when I look at it for a longer period of time, it seems to "wear faster" on me.
The Breguet also looks more "formal" to me and that is also what I al looking for ie, a nice time piece for formal events.
The eventual decison will take some months to come. I took about 7 months to finally decide on the Datograph and I have a feeling the trigger for my Perpetual Calender will take about that long too.
Nice to know that "perpetual calender technolgy" was also founded by Breguet. At least that is what I thought I deciphered from their website.
