IMHO each of those pieces is beautiful and their respective dials/fonts work well for each of them. Whenever a company puts a movement from a smaller watch into a larger case they have to do something to compensate and the subdials or date windows etc from looking like they are set too close to the center of the watch. Hence, sometimes hour markers get larger as they do at the 3 & 9 on the 5140 (compared to the smaller markers at 3& 9 on the 3940). I think if they had stuck with smaller font it would have seemed out of proportion to the new larger case and dial, and then it might create a somewhat stark or barren looking dial. I agree the Tonneau case seems ideally suited for larger font. Its a very unusual case, especially for Patek. I more commonly see that case shape (or variety of case shapes associated with VC and Cartier). While the Tonneau is still dressy, I find its a bit more relaxed and whimsical than the expected round Patek. I think its a case shape that is very under appreciated and I admire your choice of going with something thats so different from their signature round cases. As for the squished 5 and 27, I can understand your not liking it. Although, I think they handled it quite well, and IMHO its much nicer looking than when they cut out part of a number on the 5059. Just my 2 cents. Always great seeing photos of your perpetual calendars.
