Patek Philippe

Calling all Patek Philippe experts - one of my main peeves with perpetual calendars is the limited legibility of the dial. FPJ solved it perfectly with his Octa QP, and I noticed the same way of showing the date present in the two models mentioned above (... 

....the 3448 is a reference that is around 50 years old. Are you looking for references that are older than that or more modern but like the 3448?

....i am struggling. 2497 marks the very early variant....as you mention also 3448. Since then, in perpetual (ie not with chrono)....am struggling

There is something about the legibility - I could go for the annual calendar, the almost perfect 5396g, if not for the absolutely mind-boggling hideous date aperture. If they cut this out, and put the day on the moon phase it would have been a perfect wat...

As others have pointed out the movement is obviously too small for the case, thus the larger dial filled with Breguet numerals.

I would say that, from that picture below, the caliber is clearly not too small for the case. By the way, my opinion is that the way a caliber looks through a sapphire case back is subjective, like the size of a watch on a wrist is. On the front side, the...
